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
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
Amino acid deprivation therapy (AADT) is emerging as a promising strategy for the development of novel therapeutics against cancer. This biological therapy relies upon the differences in the metabolism of cancer and normal cells. The rapid growth of tumors results in decreased expression of certain enzymes leading to auxotrophy for some specific amino acids. These auxotrophic tumors are targeted by amino acid-depleting enzymes. The depletion of amino acid selectively inhibits tumor growth as the normal cells can synthesize amino acids by their usual machinery. The enzymes used in AADT are mostly obtained from microbes for their easy availability. Microbial L-asparaginase is already approved by FDA for the treatment of acute lymphoblastic leukemia. Arginine deiminase and methionase are under clinical trials and the therapeutic potential of lysine oxidase, glutaminase and phenylalanine ammonia lyase is also being explored. The present review provides an overview of microbial amino acid depriving enzymes. Various attributes of these enzymes like structure, mode of action, production, formulations, and targeted cancers are discussed. The challenges faced and the combat strategies to establish AADT in standard cancer armamentarium are also reviewed.Key Points • Amino acid deprivation therapy is a potential therapy for auxotrophic tumors. • Microbial enzymes are used due to their ease of manipulation and high productivity. • Enzyme properties are improved by PEGylation, encapsulation, and genetic engineering. • AADT can be employed as combinational therapy for better containment of cancer.

Abstract
In the present study a high arginine deiminase (ADI) yielding bacterium was isolated from soil samples of Haryana, India and identified as Pseudomonas furukawaii. The specific enzyme activity was optimized to 1.420 IU/ml by OFAT and further enhanced to 2.708 IU/ml (an increase of 90.7%) with the help of statistical parametric optimization approaches using GA-ANN and GA-ANFIS. The obtained value of the coefficient of correlation (R = 0.88) for ANN and epoch error (0.12) for ANFIS, indicates the prediction accuracy and strength of these data training models. ADI production was improved significantly in simple super broth media supplemented with 1.5% fructose and 1.75% arginine at pH 7 at 37 °C using multilevel algorithms and evolutionary hybrid tools. The native enzyme was partially purified (ten-fold) up to a specific enzyme activity of 29.559 IU/mg.

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.
