Abstract
Arginine deiminase (ADI) has garnered significant interest because of its ability to objectively eradicate cancer cells and produce L-citrulline. To meet the production demands, this study focused on enhancing the enzyme activity and thermal stability of ADI. In this study, 24 ADI mutants were obtained through computer aid site-specific mutation in the ADI of Enterobacter faecalis. Notably, the specific enzyme activities of F44W, N163P, E220I, E220L, N318E, A336G, T340I, and N382F increased, reaching 1.33-2.53 times that of the original enzyme. This study confirmed that site-specific mutations are critical for optimizing enzyme function. Additionally, the F44W, N163P, E220I, T340I, and A336G mutants demonstrated good thermal stability. The optimal pH for mutant F44W increased to 8, whereas mutants E220I, I244V, A336G, T340I, and N328F maintained an optimal pH of 7.5. Conversely, the M109L, N163P, E220L, I244L, and N318E mutants shad an optimal pH of 7. This study revealed that mutant enzymes with increased activity were more likely to contain mutation sites situated near the four loops associated with catalytic residues, whereas mutations at the dimer junction sites had a higher tendency to enhance enzyme stability. These findings contribute to the development of ADI industrial applications and its modifications.

Abstract
The anticancer potential of Levilactobacillus brevis KU15176 against the stomach cancer cell line AGS has been reported previously. In this study, we aimed to analyze the genome of L. brevis KU15176 and identify key genes that may have potential anticancer properties. Among potential anticancer molecules, the role of arginine deiminase (ADI) in conferring an antiproliferative functionality was confirmed. In vitro assay against AGS cell line confirmed that recombinant ADI from L. brevis KU15176 (ADI_br, 5 µg/mL), overexpressed in E. coli BL21 (DE3), exerted an inhibitory effect on AGS cell growth, resulting in a 65.32% reduction in cell viability. Moreover, the expression of apoptosis-related genes, such as bax, bad, caspase-7, and caspase-3, as well as the activity of caspase-9 in ADI_br-treated AGS cells, was higher than those in untreated (culture medium-only) cells. The cell-scattering behavior of ADI_br-treated cells showed characteristics of apoptosis. Flow cytometry analyses of AGS cells treated with ADI_br for 24 and 28 h revealed apoptotic rates of 11.87 and 24.09, respectively, indicating the progression of apoptosis in AGS cells after ADI_br treatment. This study highlights the potential of ADI_br as an effective enzyme for anticancer applications.

Abstract
Arginine deiminase (ADI), a promising anticancer enzyme from Mycoplasma hominis, is currently in phase III of clinical trials for the treatment of arginine auxotrophic tumors. However, it has been associated with several drawbacks in terms of low stability at human physiological conditions, high immunogenicity, hypersensitivity and systemic toxicity. In our previous work, Pseudomonas furukawaii 24 was identified as a potent producer of ADI with optimum activity under physiological conditions. In the present study, phylogenetic analysis of microbial ADIs indicated P. furukawaii ADI (PfADI) to be closely related to experimentally characterized ADIs of Pseudomonas sp. with proven anticancer activity. Immunoinformatics analysis was performed indicating lower immunogenicity of PfADI than MhADI (M. hominis ADI) both in terms of number of linear and conformational B-cell epitopes and T-cell epitope density. Overall antigenicity and allergenicity of PfADI was also lower as compared to MhADI, suggesting the applicability of PfADI as an alternative anticancer biotherapeutic. Hence, in vitro experiments were performed in which the ADI coding arcA gene of P. furukawaii was cloned and expressed in E. coli BL21. Recombinant ADI of P. furukawaii was purified, characterized and its anticancer activity was assessed. The enzyme was stable at human physiological conditions (pH 7 and 37 °C) with Km of 1.90 mM. PfADI was found to effectively inhibit the HepG2 cells with an IC50 value of 0.1950 IU/ml. Therefore, the current in silico and in vitro studies establish PfADI as a potential anticancer drug candidate with improved efficacy and low immunogenicity.

Abstract
In recent years, arginine deiminase (ADI, EC 3.5.3.6) has attracted much attention as a biocatalyst that produces the functional amino acid l-citrulline from l-arginine and also as an anticancer enzyme. Here, we identified and characterized a putative ADI from the thermophilic bacterium Halothermothrix orenii. The H. orenii ADI (H-ADI) protein was expressed in Escherichia coli BL21(DE3) with a specific activity of 91.8 U/mg protein at 55°C and pH 6.5. The enzyme remained at 74% relative activity after incubation at 45°C for 180 min, only 25% at 50°C. The melting temperature was 56°C. H-ADI is not a metal-requiring enzyme; Ni2+ slightly improved the catalytic activity. The Km and Vmax for l-arginine were 55.5 mM and 156.8 μmol/min/mg protein, respectively. Moreover, three residues (Arg183, Arg237, and His273) were key to the formation of l-citrulline, as analyzed by alanine-scanning mutagenesis. Finally, the enzymatic synthesis of l-citrulline was carried out at 50°C with a conversion ratio reaching 99.03%. Together, these findings show that H-ADI is a promising biocatalyst for the production of l-citrulline.

Abstract
Arginine deiminase is a well-recognized guanidino-modifying hydrolase that catalyzes the conversion of L-arginine to citrulline and ammonia. Their biopotential to regress tumors via amino acid deprivation therapy (AADT) has been well established. PEGylated formulation of recombinant Mycoplasma ADI is in the last-phase clinical trials against various arginine-auxotrophic cancers like hepatocellular carcinoma, melanoma, and mesothelioma. Recently, ADIs have attained immense importance in several other biomedical applications, namely treatment of Alzheimer's, as an antiviral drug, bioproduction of nutraceutical L-citrulline and bio-analytics involving L-arginine detection. Considering the wide applications of this biodrug, the demand for ADI is expected to escalate several-fold in the coming years. However, the sustainable production aspects of the enzyme with improved pharmacokinetics is still limited, creating bottlenecks for effective biopharmaceutical development. To circumvent the lacunae in enzyme production with appropriate paradigms of 'quality-by-design' an explicit overview of its properties with 'biobetter' formulations strategies are required. Present review provides an insight into all the potential biomedical applications of ADI along with the improvements required for its reach to clinics. Recent research advances with special emphasis on the development of ADI as a 'biobetter' enzyme have also been comprehensively elaborated.

Abstract
Extensive studies have shown that cancer cells have specific nutrient auxotrophy and thus have much a higher demand for certain nutrients than normal cells. Amino acid deprivation has attracted much attention in cancer therapy with positive outcomes from clinical trials. Arginine, as one of the conditionally essential amino acids, plays a pivotal role in cellular division and metabolism. Since many types of cancer cells exhibit decreased expression of argininosuccinate synthetase and/or ornithine transcarbamylase, they are auxotrophic for arginine, which makes arginine deprivation an accessible choice for cancer treatment. Arginine deiminase (ADI) and human arginase (hArg) are the two major protein drugs used for arginine deprivation and are undergoing many clinical trials. However, the clinical application of ADI and hArg is facing some common problems, including their short half-lives, immunogenicity and inconsistent production, which underlines the importance of improving these drugs using protein engineering techniques. Thus, we systematically review the latest studies of protein engineering and anti-cancer studies based on in vitro, in vivo and clinical models of ADI and hArg, and we include the latest studies on drug combinations consisting of ADI/hArg with chemotherapeutic drugs.

Abstract
L-arginine (L-Arg) depletion induced by randomly PEGylated arginine deiminase (ADI-PEG20) can treat arginosuccinate synthase (ASS)-negative cancers, and ADI-PEG20 is undergoing phase III clinical trials. Unfortunately, ASS-positive cancers are resistant to ADI-PEG20. Moreover, the yield of ADI production is low because of the formation of inclusion bodies. Here, we report a thermostable arginine-depleting enzyme, Bacillus caldovelox arginase mutant (BCA-M: Ser161->Cys161). An abundant amount of BCA-M was easily obtained via high cell-density fermentation and heat treatment purification. Subsequently, we prepared BCA-M-PEG20, by conjugating a single 20 kDa PEG monomer onto the Cys161 residue via thio-chemistry. Unlike ADI-PEG20, BCA-M-PEG20 significantly inhibited ASS-positive lung cancer cell growth. Pharmacodynamic studies showed that a single intraperitoneal injection (i.p). administration of 250 U/mouse of BCA-M-PEG20 induced low L-Arg level over 168 h. The mono-PEGylation of BCA-M prolonged its elimination half-life from 6.4 to 91.4 h (a 14-fold increase). In an A549 lung cancer xenograft model, a weekly administration of 250 U/mouse of BCA-M-PEG20 suppressed tumor growth significantly. We also observed that BCA-M-PEG20 did not cause any significant safety issue in mouse models. Overall, BCA-M-PEG20 showed excellent results in drug production, potency, and stability. Thereby, it has great potential to become a promising candidate for lung cancer therapy.

Abstract
In cells, the breakdown of arginine to ornithine and ammonium ion plus carbon dioxide is coupled to the generation of metabolic energy in the form of ATP. The arginine breakdown pathway is minimally composed of arginine deiminase, ornithine transcarbamoylase, carbamate kinase, and an arginine/ornithine antiporter; ammonia and carbon dioxide most likely diffuse passively across the membrane. The genes for the enzymes and transporter have been cloned and expressed, and the proteins have been purified from Lactococcus lactis IL1403 and incorporated into lipid vesicles for sustained production of ATP. Here, we study the kinetic parameters and biochemical properties of the individual enzymes and the antiporter, and we determine how the physicochemical conditions, effector composition, and effector concentration affect the enzymes. We report the KM and VMAX values for catalysis and the native oligomeric state of all proteins, and we measured the effect of pathway intermediates, pH, temperature, freeze-thaw cycles, and salts on the activity of the cytosolic enzymes. We also present data on the protein-to-lipid ratio and lipid composition dependence of the antiporter.

Abstract
In the present study, arginine deaminase (ADI) was purified from Pseudomonas aeruginosa PS2 which showed relative molecular mass of 70 ± 3 kDa on native-PAGE and 36 ± 0.5 kDa on SDS-PAGE. Purified ADI exhibited optimum activity at pH 6.5 and temperature 40 ºC. Metal ions, K+ and Mg2+ had positive, while Mn2+, Cr2+, Co2+, Fe3+, Ni2+, Cu2+, Cd2+ and Hg2+ had negative effects on catalytic activity of ADI. Purified enzyme showed high substrate specificity towards natural substrate L-arginine and did not hydrolyse its structural analogues. In-vitro serum half-life of purified ADI was 40 h, whereas proteolytic half-life was 28, 27, and 32 min against trypsin, elastase-I and proteinase-K, respectively. Anticancer activity of ADI has been evaluated against panel of human cancer cell lines (LS-180, HCT-116, MCF-7, BT-549, T47D, HL-60, MOLT-4, K-562, and PC-3) but lowest IC50 1.2 IU ml-1 was recorded with MCF-7 cells. Colony forming assay, wound-healing migration assay, phase contrast microscopy, DAPI staining, cell cycle analysis and DNA laddering assay revealed that ADI treatment induced apoptotic cell death in dose dependent manner. Increased level of MMP loss, ROS generation and decreased level of SOD, CAT, GPx and GSH displayed ADI treatment induced mitochondrial dysfunctioning. Furthermore, purified ADI had no substantial toxicity against human normal cell lines and blood erythrocytes. These findings suggesting that purified ADI could be developed as an anticancer agent but more in depth studies are warranted.

Abstract
BACKGROUND Arginine deiminase is a bacterial enzyme, which degrades L-arginine. Some human cancers such as hepatocellular carcinoma (HCC) and melanoma are auxotrophic for arginine. Therefore, PEGylated arginine deiminase (ADI-PEG20) is a good anticancer candidate with antitumor effects. It causes local depletion of L-arginine and growth inhibition in arginineauxotrophic tumor cells. The FDA and EMA have granted orphan status to this drug. Some recently published patents have dealt with this enzyme or its PEGylated form. OBJECTIVE Due to increasing attention to it, we aimed to evaluate and compare 30 arginine deiminase proteins from different bacterial species through in silico analysis. METHODS The exploited analyses included the investigation of physicochemical properties, multiple sequence alignment (MSA), motif, superfamily, phylogenetic and 3D comparative analyses of arginine deiminase proteins thorough various bioinformatics tools. RESULTS The most abundant amino acid in the arginine deiminase proteins is leucine (10.13%) while the least amino acid ratio is cysteine (0.98%). Multiple sequence alignment showed 47 conserved patterns between 30 arginine deiminase amino acid sequences. The results of sequence homology among 30 different groups of arginine deiminase enzymes revealed that all the studied sequences located in amidinotransferase superfamily. Based on the phylogenetic analysis, two major clusters were identified. Considering the results of various in silico studies; we selected the five best candidates for further investigations. The 3D structures of the best five arginine deiminase proteins were generated by the I-TASSER server and PyMOL. The RAMPAGE analysis revealed that 81.4%-91.4%, of the selected sequences, were located in the favored region of arginine deiminase proteins. CONCLUSION The results of this study shed light on the basic physicochemical properties of thirty major arginine deiminase sequences. The obtained data could be employed for further in vivo and clinical studies and also for developing the related therapeutic enzymes.

Abstract
BACKGROUND Arginine deiminase (ADI), an arginine catabolizing enzyme, is considered as an anti-tumor agent for the treatment of arginine auxotrophic cancers. However, some obstacles limit its clinical applications. OBJECTIVE This review will summarize the clinical applications of ADI, from a brief history to its limitations, and will discuss the different ways to deal with the clinical limitations. METHOD The structure analysis, cloning, expression, protein engineering and applications of arginine deiminase enzyme have been explained in this review. CONCLUSION Recent patents on ADI are related to ADI engineering to increase its efficacy for clinical application. The intracellular delivery of ADI and combination therapy seem to be the future strategies in the treatment of arginine auxotrophic cancers. Applying ADIs with optimum features from different sources and or ADI engineering, are promising strategies to improve the clinical application of ADI.

Dietary Probiotic Effect of Lactococcus lactis WFLU12 on Low-Molecular-Weight Metabolites and Growth of Olive Flounder ( Paralichythys olivaceus). Front Microbiol 2018; 9:2059.

Abstract
The use of probiotics is considered an attractive biocontrol method. It is effective in growth promotion in aquaculture. However, the mode of action of probiotics in fish in terms of growth promotion remains unclear. The objective of the present study was to investigate growth promotion effect of dietary administration of host-derived probiotics, Lactococcus lactis WFLU12, on olive flounder compared to control group fed with basal diet by analyzing their intestinal and serum metabolome using capillary electrophoresis mass spectrometry with time-of flight (CE-TOFMS). Results of CE-TOFMS revealed that 53 out of 200 metabolites from intestinal luminal metabolome and 5 out of 171 metabolites from serum metabolome, respectively, were present in significantly higher concentrations in the probiotic-fed group than those in the control group. Concentrations of metabolites such as citrulline, tricarboxylic acid cycle (TCA) intermediates, short chain fatty acids, vitamins, and taurine were significantly higher in the probiotic-fed group than those in the control group. The probiotic strain WFLU12 also possesses genes encoding enzymes to help produce these metabolites. Therefore, it is highly likely that these increased metabolites linked to growth promotion in olive flounder are due to supplementation of the probiotic strain. To the best of our knowledge, this is the first study to show that dietary probiotics can greatly influence metabolome in fish. Findings of the present study may reveal important implications for maximizing the efficiency of using dietary additives to optimize fish health and growth.

Abstract
l-Citrulline is a nonessential amino acid with a variety of physiological functions and can be enzymatically produced by arginine deiminase (ADI, EC 3.5.3.6). The enzymatic-production approach is of immense interest because of its mild conditions, high yield, low cost, and environmental benignity. However, the major hindrances of l-citrulline industrialization are the poor thermostability and enzyme activity of ADI. Hence, in this work, directed evolution and site-directed mutagenesis aided with in silico screening, including the use of b-factor values and HoTMuSiC, were applied to a previously identified ADI from Enterococcus faecalis SK23.001 ( EfADI), and a triple-site variant R15K-F269Y-G292P was obtained. The triple-site variant displays a 2.5-fold higher specific enzyme activity (333 U mg-1), a lower Km value of 6.4 mM, and a 6.1-fold longer half-life ( t1/2,45°C = 86.7 min) than wild-type EfADI. This work provides a protein-engineering strategy to improve enzyme activity and thermostability, which might be transferrable to other ADIs and enzymes.

Abstract
BACKGROUND Arginine deiminase (ArcA) has been speculated to facilitate the intracellular survival of Streptococcus suis under acidic conditions. However, the physical and biological properties and function of SS2-ArcA have not yet been elucidated. METHODS Recombinant SS2-ArcA (rSS2-ArcA) was expressed and purified using Ni-NTA affinity chromatography. Under various pH and temperature conditions, the enzymatic properties of purified rSS2-ArcA and crude native SS2-ArcA were determined. RESULTS The SS2-arcA-deduced amino acid sequence contained a conserved catalytic triad (Cys399-His273-Glu218). The optimum temperature and pH of 47-kDa rSS2-ArcA and crude native SS2-ArcA were 42°C and pH 7.2. The rSS2-ArcA and crude native SS2-ArcA were stable for 3 h at 4 and 25°C, respectively. The pH stability and dependency tests suggested that rSS2-ArcA and crude native SS2-ArcA were functionally active in acidic conditions. The L-arginine substrate binding affinity (Km) values of rSS2-ArcA (specific activity 16.00 U/mg) and crude native SS2-ArcA (specific activity 0.23 U/mg) were 0.058 and 0.157 mM, respectively. rSS2-ArcA exhibited a weak binding affinity with the common ArcA inhibitors L-canavanine and L-NIO. Furthermore, the partial inactivation of SS2-ArcA significantly impaired the viability and growth of SS2 at pH 4.0, 6.0, and 7.5. CONCLUSIONS This study profoundly demonstrated the involvement of ArcA enzymatic activity in S. suis survival under acidic conditions.

Abstract
The Pseudomonas putida arginine deiminase (ADI), a natural cytosolic enzyme, and Thermobifida fusca cutinase were co-expressed in Escherichia coli, and the optimized cutinase gene was used for increasing its expression level. 90.9% of the total ADI protein was released into culture medium probably through a nonspecific leaking mechanism caused by the co-expressed cutinase. The enzymatic properties of the extracellular ADI were found to be similar to those of ADI prepared by conventional cytosolic expression. Extracellular production of ADI was further scaled up in a 3-L fermentor. When the protein expression was induced by IPTG (25.0μM) and lactose (0.1gL(-1)h(-1)) at 30°C, the extracellular ADI activity reached 101.2UmL(-1), which represented the highest ADI production ever reported. In addition, the enzymatic synthesis of l-citrulline was performed using the extracellularly expressed ADI, and the conversion rate reached 100% with high substrate concentration at 650gL(-1).

Abstract
The arginine deiminase (ADI, E.C 3.5.3.6) - a key enzyme of ADI pathway of Enterococcus faecium GR7 was purified to homogeneity. A sequential purification strategy involving ammonium sulfate fractionation, molecular sieve followed by Sephadex G-100 gel filtration was applied to the crude culture filtrate to obtain a pure enzyme preparation. The enzyme was purified with a fold of 16.92 and showed a final specific activity of 76.65IU/mg with a 49.17% yield. The dimeric ADI has a molecular mass of about 94,364.929Da, and comprises of hetrodimers of 49.1kDa and 46.5kDa as determined by MALDI-TOF and PAGE analysis. To assess anti-cancerous activity of ADI by MTT assay was carried out against cancer cell lines (MCF-7, Sp2/0-Ag14 and Hep-G2). Purified ADI exhibited the most profound antiproliferative activity against Hep-G2 cells; with half-maximal inhibitory concentration (IC50) of 1.95μg/ml. Purified ADI from E. faecium GR7 was observed to induce apoptosis in the Hep-G2 cells by DNA fragmentation assay. Our findings suggest the possibility of a future use of ADI from E. faecium GR7 as a potential anticancer drug.

Abstract
In this study, a simple, efficient enzymatic production process for the environmentally friendly synthesis of l-citrulline from l-arginine was developed using arginine deiminase (ADI) from Lactococcus lactis. Following overexpression of L. lactis ADI in Escherichia. coli BL21 (DE3) and experimental evolution using error-prone PCR, mutant FMME106 was obtained with a Km for l-arginine of 3.5mM and a specific activity of 195.7U/mg. This mutant exhibited a maximal conversion of 92.6% and achieved a final l-citrulline concentration of 176.9g/L under optimal conditions (190g/L l-arginine, 15g/L whole-cell biocatalyst treated with 2% isopropanol for 30min, 50°C, pH 7.2, 8h). The average l-citrulline synthesis rate of 22.1g/L/h is considerably higher than that reported for other similar biocatalytic approaches, therefore the process developed in the present work has great potential for large-scale production of l-citrulline.

Abstract
l-Arginine deiminase (ADI) has a powerful anticancer activity against various tumors, via arginine depletion, arresting the cell cycle at G1 phase. However, the current clinically tried bacterial ADI displayed a higher antigenicity and lower thermal stability. Thus, our objective was to purify and characterize this enzyme from thermophilic fungi, to explore its catalytic and antigenic properties for therapeutic uses. ADI was purified from thermophilic Aspergillus fumigatus KJ434941 to its electrophoretic homogeneity by 5.1-fold, with molecular subunit 50 kDa. The purified ADI was PEGylated and covalently immobilized on dextran to explore its catalytic properties. The specific activity of free ADI, PEG-ADI, and Dex-ADI was 26.7, 21.5, and 18.0 U/mg, respectively. At 50°C, PEG-ADI displays twofold resistance to thermal denaturation (t1/2 13.9 h), than free ADI (t1/2 6.9 h), while at 70°C, the thermal stability of PEG-ADI was increased by 1.7-fold, with similar stability to Dex-ADI with the free one. Kinetically, free ADI had the higher catalytic affinity to arginine, followed by PEG-ADI and Dex-ADI. Upon proteolysis for 30 min, the residual activity of native ADI, PEG-ADI, and Dex-AD was 8.0, 32.0, and 20.0% for proteinase K and 10.0, 52.0, and 90.0% for acid protease, respectively. The anticancer activity of the ADIs was assessed against HCT, HEP-G2, and MCF7, in vitro. The free and PEG-ADI exhibits a similar cytotoxic efficacy for the tested cells, lower than Dex-ADI. The free ADI had IC50 value 22.0, 16.6, and 13.9 U/mL, while Dex-ADI had 3.98, 5.18, and 4.43 U/mL for HCT, MCF7, and HEPG-2, respectively. The in vitro anticancer activity of ADI against HCT, MCF7, and HEPG-2 was increased by five-, three-, and threefold upon covalent modification by dextran. The biochemical and hematological parameters of the experimented animals were not affected by ADIs dosing, with no signs of anti-ADI immunoglobulins in vivo. The in vivo half-life time of free ADI, PEG-ADI, and Dex-ADI was 29.7, 91.1, 59.6 h, respectively. The present findings explored a novel thermostable, less antigenic ADI from thermophilic A. fumigatus, with further molecular and crystallographic analyses, this enzyme will be a powerful candidate for clinical trials.

Abstract
L-Arginase, hydrolyzing L-arginine to L-ornithine and urea, is a powerful anticancer, L-arginine-depleting agent, against argininosuccinate synthase expressing tumors. Otherwise, the higher antigenicity and lower thermal stability of this enzyme was the main biochemical hurdles. Since, the intrinsic thermal stability of enzymes follow the physiological temperature of their producer, thus, characterization of L-arginase from thermotolerant Penicillium chrysogenum was the objective of this study. L-Arginase (Arg) was purified to its homogeneity from P. chrysogenum by 10.1-fold, with 37.0 kDa under denaturing PAGE, optimum reaction at 50 °C, pH stability (6.8-7.9), with highest molar ratio of constitutional arginine, glutamic acid, lysine and aspartic acid. The purified enzyme was PEGylated and immobilized on chitosan, with 41.9 and 22.1 % yield of immobilization. At 40 °C, the T1/2 value of free-Arg, PEG-Arg and Chit-Arg was 10.4, 15.6, 20.5 h, respectively. The free-Arg and Chit-Arg have a higher affinity to L-arginine (K m 4.8 mM), while, PEG-Arg affinity was decreased by about 3 fold (K m 15.2 mM). The inhibitory constants to the free and PEG-Arg were relatively similar towards HA and PPG. The IC50 for the free enzyme against HEPG-2 and A549 tumor cells was 0.136 and 0.165 U/ml, comparing to 0.232 and 0.496 U/ml for PEG-Arg, respectively. The in vivo T1/2 to the free Arg and PEG-Arg was 16.4 and 20.4 h, respectively as holo-enzyme. The residual L-arginine level upon using free Arg was 156.9 and 144.5 µM, after 6 and 8 h, respectively, regarding to initials at 253.6 µM, while for Peg-Arg the level of L-arginine was nil till 7 h of initial dosing. The titer of IgG was induced by 10-15 % in response to free-Arg after 28 days comparing to IgG titer for PEG-Arg.

Abstract
Arginine deiminase (ADI) is a therapeutic protein for cancer therapy of arginine-auxotrophic tumors. However, ADI's application as anticancer drug is hampered by its low activity for arginine under physiological conditions mainly due to its high "K M" (S₀.₅) values which are often 1 magnitude higher than the arginine concentration in blood (0.10-0.12 mM arginine in human plasma). Previous evolution campaigns were directed by us with the aim of boosting activity of PpADI (ADI from Pseudomonas plecoglossicida, k cat = 0.18 s(-1); S₀.₅ = 1.30 mM), and yielded variant M6 with slightly reduced S₀.₅ values and enhanced k cat (S₀.₅ = 0.81 mM; k cat = 11.64 s(-1)). In order to further reduce the S₀.₅ value and to increase the activity of PpADI at physiological arginine concentration, a more sensitive screening system based on ammonia detection in 96-well microtiter plate to reliably detect ≥0.005 mM ammonia was developed. After screening ~5,500 clones with the ammonia detection system (ADS) in two rounds of random mutagenesis and site-directed mutagenesis, variant M19 with increased k cat value (21.1 s(-1); 105.5-fold higher compared to WT) and reduced S₀.₅ value (0.35 mM compared to 0.81 mM (M6) and 1.30 mM (WT)) was identified. Improved performance of M19 was validated by determining IC₅₀ values for two melanoma cell lines. The IC₅₀ value for SK-MEL-28 dropped from 8.67 (WT) to 0.10 (M6) to 0.04 μg/mL (M19); the IC₅₀ values for G361 dropped from 4.85 (WT) to 0.12 (M6) to 0.05 μg/mL (M19).

Abstract
BACKGROUND Overexpression of foreign genes in Escherichia coli cells is an efficient means to obtain recombinant proteins. The technique is, however, often hampered by misfolding, degradation, aggregation and formation in inclusion bodies of products. RESULTS In this study, we reported that in vivo solubility of overexpressed arginine deiminases (ADI) improved by changing the cultivation conditions. ADI is enzymes that convert L-arginine to L-citrulline. After codon optimization, we synthesized the ADI gene of Pseudomonas putida and constructed it for overexpression in E. coli cells. The rADI products were mainly in inclusion body forms. We performed a series of optimization to enhance solubility of the protein. Co-expression with the GroES-GroEL chaperone team increased approximately 5-fold of the rADI activity. In addition the combination of L-arginine and D-glucose in the Luria-Bertani (LB) growth medium further increased the total activity to about 15 times. Separate L-arginine and D-glucose or the addition of other saccharides or amino acids had no such effects. The solubilization effects of the combination of L-arginine and D-glucose were further confirmed in the overexpression of another ADI from Listeria welshimeri. The enzymatic and conversion characteristics of the rADI products were further determined. CONCLUSIONS Combined addition of L-arginine and D-glucose in the LB medium significantly improved in vivo solubility of rADI proteins. The present study suggested a new strategy to increase the solubilization of overexpressed recombinant proteins in E. coli cells.

Application of response surface methodology for optimizing arginine deiminase production medium for Enterococcus faecium sp. GR7. ScientificWorldJournal 2013; 2013:892587. [PMID: 24453919 PMCID: PMC3877641 DOI: 10.1155/2013/892587] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2013] [Accepted: 09/23/2013] [Indexed: 11/30/2022] Open
Abstract
Arginine metabolism in Enterococcus faecium sp. GR7 was enhanced via arginine deiminase pathway. Process parameters including fermentation media and environmental conditions were optimized using independent experiments and response surface methodology (central composite design). Fermentation media (EAPM) were optimized using independent experiments which resulted in 4-fold increase in arginine deiminase specific activity as compared to basal medium. To further enhance arginine deiminase activity in E. faecium sp. GR7 and biomass production including a five-level central composite design (CCD) was employed to study the interactive effect of three-process variables. Response surface methodology suggested a quadratic model which was further validated experimentally where it showed approximately 15-fold increase in arginine metabolism (in terms of arginine deiminase specific activity) over basal medium. By solving the regression equation and analyzing the response surface cartons, optimal concentrations of the media components (g/L) were determined as arginine 20.0; tryptone 15.0; lactose 10.0; K2HPO4 3.0; NaCl 1.0, MnSO4 0.6 mM; Tween 80 1%; pH 6.0 for achieving specific arginine deiminase activity of 4.6 IU/mG with concomitant biomass production of 12.1 mg/L. The model is significant as the coefficient of determination (R2) was 0.87 to 0.90 for all responses. Enhanced arginine deiminase yield from E. faecium, a GRAS lactic acid bacterial strain, is desirable to explore in vitro therapeutic potential of the arginine metabolizing E. faecium sp. GR7.

Abstract
Streptococcus pyogenes (group A Streptococcus, GAS) is an important human pathogen causing mild superficial infections of skin and mucous membranes, but also life-threatening systemic diseases. S. pyogenes and other prokaryotic organisms use the arginine deiminase system (ADS) for survival in acidic environments. In this study, the arginine deiminase (AD), and carbamate kinase (CK) from S. pyogenes M49 strain 591 were heterologously expressed in Escherichia coli DH5α, purified, and kinetically characterized. AD and CK from S. pyogenes M49 share high amino acid sequence similarity with the respective enzymes from Lactococcus lactis subsp. lactis IL1403 (45.6% and 53.5% identical amino acids) and Enterococcus faecalis V583 (66.8% and 66.8% identical amino acids). We found that the arginine deiminase of S. pyogenes is not allosterically regulated by the intermediates and products of the arginine degradation (e.g., ATP, citrulline, carbamoyl phosphate). The Km and Vmax values for arginine were 1.13±0.12mM (mean±SD) and 1.51±0.07μmol/min/mg protein. The carbamate kinase is inhibited by ATP but unaffected by arginine and citrulline. The Km and Vmax values for ADP were 0.72±0.08mM and 1.10±0.10μmol/min/mg protein and the Km for carbamoyl phosphate was 0.65±0.07mM. The optimum pH and temperature for both enzymes were 6.5 and 37°C, respectively.

Abstract
There are multiple lines of evidence that lactic acid bacteria (LAB) exert cancer-preventive effects. However, the underlying mechanisms are poorly understood. In the present study we found that the cytoplasmic fraction of Lactococcus lactis ssp. lactis American Type Culture Collection (ATCC) 7962 exerted the strongest antiproliferative effects (half-maximal inhibitory concentration (IC50) = 17 microg/ml) in SNU-1 human stomach cancer cells and arginine deiminase (ADI; EC 3.5.3.6) activity. We also cloned, expressed and purified ADI from L. lactis ssp. lactis ATCC 7962 (LADI). Both purified ADI from L. lactis (PADI; IC50 = 2 microg/ml) and recombinant ADI originating from LADI (IC50 = 0.6 microg/ml) inhibited the proliferation of SNU-1 cells. LADI induced G0/G1-phase arrest, sub-G1 accumulation, DNA condensation and DNA fragmentation in SNU-1 cells. 4',6-Diamidino-2-phenylindole (DAPI) staining and DNA fragmentation data provide evidence that LADI induces apoptosis in SNU-1 cells. LADI increased the expressions of p53 and p27Kip1, and decreased the expressions of cyclin D1, c-myc and Bcl-xL in SNU-1 cells. However, LADI had no effects on the expressions of p21Cip1 and Bcl-2. Collectively, these data indicate that ADI induces apoptosis and G0/G1-phase arrest of SNU-1 cells, which might contribute to the chemopreventive potential of LAB.

Abstract
Arginine deiminase (ADI; EC 3.5.3.6), an arginine-degrading enzyme, has been studied as a potential anti-tumor drug for the treatment of arginine-auxotrophic tumors, such as hepatocellular carcinomas (HCCs) and melanomas. Studies with human lymphatic leukemia cell lines further suggest that ADI is a potential anti-angiogenic agent and is effective in the treatment of leukemia. For instance ADI-PEG-20, patented by Pheonix Pharmacologic Inc., is currently in clinical trials for the treatment of HCC (Phase II/III) and melanoma (Phase I/II). This review summarizes results on recombinant expression, structural analysis, PEG (polyethylene glycerol) modification, in vivo anti-cancer activities, and clinical studies of ADI. Discussions on heterogeneous expression of ADI, directed evolution for improving enzymatic properties, and HSA-fusion for increased in vivo activity conclude this review.
