Wang J, Liu X, Jing Y, Zheng X. Purification and Biochemical Characterization of a Novel Fibrinolytic Enzyme from Culture Supernatant of Coprinus comatus. Foods 2024; 13:1292. [PMID: 38731663 PMCID: PMC11083162 DOI: 10.3390/foods13091292] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2024] [Revised: 04/19/2024] [Accepted: 04/20/2024] [Indexed: 05/13/2024] Open
Abstract
A novel fibrinolytic enzyme was produced by the liquid fermentation of Coprinus comatus. The enzyme was purified from the culture supernatant by hydrophobic interactions, gel filtration, and ion exchange chromatographies. It was purified by 241.02-fold, with a specific activity of 3619 U/mg and a final yield of 10.02%. SDS-PAGE analysis confirmed the purity of the enzyme, showing a single band with a molecular weight of 19.5 kDa. The first nine amino acids of the N-terminal of the purified enzyme were A-T-Y-T-G-G-S-Q-T. The enzyme exhibited optimal activity at a temperature of 42 °C and pH 7.6. Its activity was significantly improved by Zn2+, K+, Ca2+, Mn2+, and Mg2+ while being inhibited by Fe2+, Fe3+, Al2+, and Ba2+. The activity of the enzyme was completely inhibited by ethylenediamine tetraacetic acid (EDTA), and it was also dose-dependently inhibited by phenylmethylsulfonyl fluoride (PMSF) and soy trypsin inhibitor (SBTI). However, inhibitors such as N-α-tosyl-L-phenylalanine chloromethyl ketone (TPCK), aprotinin, and pepstatin did not significantly affect its activity, suggesting that the enzyme was a serine-like metalloproteinase. The enzyme acted as both a plasmin-like fibrinolytic enzyme and a plasminogen activator, and it also exhibited the capability to hydrolyze fibrinogen and fibrin. In vitro, it demonstrated the ability to dissolve blood clots and exhibit anticoagulant properties. Furthermore, it was found that the enzyme prolonged activated partial thromboplastin time (APTT), prothrombin time (PT), and thrombin time (TT), and reduced the levels of fibrinogen (FIB) and prothrombin activity (PA). Based on these studies, the enzyme has great potential to be developed as a natural agent for the prevention and treatment of thrombotic diseases.

Abstract
Mushrooms are a source of primary and secondary metabolites. Little is known about the most suitable conditions for production of mushrooms by submerged fermentation. This article reports antioxidant and cytotoxic assays, in addition to quantitatively evaluating the content of proteases with fibrinolytic action in the crude extracts of two species of edible mushrooms produced in different formulations, as well as evaluating the recovery of these enzymes by aqueous two-phase systems (ATPS). The mushrooms Pleurotus ostreatus and Pleurotus eryngii, at concentration of 100 µg/mL, displayed inhibition of DPPH and ABTS radicals below 50%. In the cytotoxicity test, the cells human fibroblast cell lines (MRC-5) showed cell viability greater than 80%. Concerning fibrinolytic activity, P. eryngii presented 226.47 ± 7.26 U/mL, therefore being more efficient than P. ostreatus (71.5 ± 0.56 U/mL). In the recovery of the P. eryngii extract by ATPS, the fibrinolytic protease was partitioned in the salt phase (30.25 U/mL). The molecular mass of the proteases was between 75 and 100 kDa. These results prove the low cytotoxicity of the extracts produced and that fermentation in supplemented malt broth favored the excretion of fibrinolytic proteases compared to the other evaluated media.

Abstract
Fibrinolytic enzymes cleave fibrin which plays a crucial role in thrombus formation which otherwise leads to cardiovascular diseases. While different fibrinolytic enzymes have been purified, only a few have been utilized as clinical and therapeutic agents; hence, the search continues for a fibrinolytic enzyme with high specificity, fewer side effects, and one that can be mass-produced at a lower cost with a higher yield. In this context, this review discusses the physiological mechanism of thrombus formation and fibrinolysis, and current thrombolytic drugs in use. Additionally, an overview of the optimization, production, and purification of fibrinolytic enzymes and the role of Artificial Intelligence (AI) in optimization and the patents granted is provided. This review classifies microbial as well as non-microbial fibrinolytic enzymes isolated from food sources, including fermented foods and non-food sources, highlighting their advantages and disadvantages. Despite holding immense potential for the discovery of novel fibrinolytic enzymes, only a few fermented food sources limited to Asian countries have been studied, necessitating the research on fibrinolytic enzymes from fermented foods of other regions. This review will aid researchers in selecting optimal sources for screening fibrinolytic enzymes and is the first one to provide insights and draw a link between the implication of source selection and in vivo application.

Abstract
Fungal fibrinolytic enzymes, secreted by some Agaricomycetes, are recognized as important thrombolytic agents due to their ability to rapidly dissolve thromboembolic clots. The present work evaluated fibrinolytic and proteolytic secretion abilities of 35 Agaricomycetes isolates from the Paranaense rainforest (Misiones, Argentina). We detected proteolytic activity in 40% of the strains while nine strains showed fibrinolytic activity. Schizophyllum commune LBM 026, Schizophyllum commune LBM 223, and Hornodermoporus martius LBM 224 exhibited the highest levels of fibrinolytic activity. Fibrin zymography from S. commune LBM 026 and LBM 223 showed an enzyme of 27.5 kDa, while H. martius LBM 224 presented an enzyme of 29 kDa. The evaluation of the enzymatic stability of culture supernatant of these strains revealed that the fibrinolytic activity was highly stable over a wide temperature and pH range. Long-term stability of fibrinolytic activity at physiological conditions evidenced that the strains had a half-life of at least 72 h. Fibrinolytic enzymes produced by S. commune LBM 026 and LBM 223 were inhibited in the presence of EDTA indicating that they are metalloproteases. This work reveals the potential of S. commune LBM 026, S. commune LBM 223, and H. martius LBM 224 as an unconventional source of thrombolytic agents.

Abstract
Cardiac disorders such as acute myocardial infarction, embolism and stroke are primarily attributed to excessive fibrin accumulation in the blood vessels, usually consequential in thrombosis. Numerous methodologies including the use of anti-coagulants, anti-platelet drugs, surgical operations and fibrinolytic enzymes are employed for the dissolution of fibrin clots and hence ameliorate thrombosis. Microbial fibrinolytic enzymes have attracted much more attention in the management of cardiovascular disorders than typical anti-thrombotic strategies because of the undesirable after-effects and high expense of the latter. Fibrinolytic enzymes such as plasminogen activators and plasmin-like proteins hydrolyse thrombi with high efficacy with no significant after-effects and can be cost effectively produced on a large scale with a short generation time. However, the hunt for novel fibrinolytic enzymes necessitates complex purification stages, physiochemical and structural-functional attributes, which provide an insight into their mechanism of action. Besides, strain improvement and molecular technologies such as cloning, overexpression and the construction of genetically modified strains for the enhanced production of fibrinolytic enzymes significantly improve their thrombolytic potential. In addition, the unconventional applicability of some fibrinolytic enzymes paves their way for protein hydrolysis in addition to fibrin/thrombi, blood pressure regulation, anti-microbials, detergent additives for blood stain removal, preventing dental caries, anti-inflammatory and mucolytic expectorant agents. Therefore, this review article encompasses the production, biochemical/structure-function properties, thrombolytic potential and other surplus applications of microbial fibrinolytic enzymes.

Abstract
Enzyme therapies are attracting significant attention as thrombolytic drugs during the current scenario owing to their great affinity, specificity, catalytic activity, and stability. Among various sources, the application of microbial-derived thrombolytic and fibrinolytic enzymes to prevent and treat vascular occlusion is promising due to their advantageous cost-benefit ratio and large-scale production. Thrombotic complications such as stroke, myocardial infarction, pulmonary embolism, deep venous thrombosis, and peripheral occlusive diseases resulting from blood vessel blockage are the major cause of poor prognosis and mortality. Given the ability of microbial thrombolytic enzymes to dissolve blood clots and prevent any adverse effects, their use as a potential thrombolytic therapy has attracted great interest. A better understanding of the hemostasis and fibrinolytic system may aid in improving the efficacy and safety of this treatment approach over classical thrombolytic agents. Here, we concisely discuss the physiological mechanism of thrombus formation, thrombo-, and fibrinolysis, thrombolytic and fibrinolytic agents isolated from bacteria, fungi, and algae along with their mode of action and the potential application of microbial enzymes in thrombosis therapy.

Abstract
A novel fibrinolytic enzyme, ACase was isolated from fruiting bodies of a mushroom, Agrocybe aegerita. ACase was purified by using ammonium sulfate precipitation, gel filtration, ion exchange and hydrophobic chromatographies to 237.12 fold with a specific activity of 1716.77 U/mg. ACase was found to be a heterodimer with molecular mass of 31.4 and 21.2 kDa by SDS-PAGE and appeared as a single band on Native-PAGE and fibrin-zymogram. The N-terminal sequence of the two subunits of ACase was AIVTQTNAPWGL (subunit 1) and SNADGNGHGTHV (subunit 2). ACase had maximal activity at 47 °C and pH 7.6. It's activity was improved by Cu2+, Na+, Fe3+, Zn2+, Ba2+, K+ and Mn2+, but inhibited by Fe2+, Mg2+ and Ca2+. PMSF, SBTI, aprotinine and Lys inhibited the enzyme activity, which suggested that ACase was a serine protease. ACase could degrade all three chains (α, β and γ) of fibrinogen. Moreover, the enzyme acted as both, a plasmin-like fibrinolytic enzyme and a plasminogen activator. It could hydrolyze human thrombin slightly, which indicated that the ACase could inhibit the activity of thrombin and acted as an anticoagulant to prevent thrombosis. Based on these results, ACase might act as a therapeutic agent for treating thrombosis, or as a functional food. Further investigation of the enzyme is underway.

Abstract
Fibrinolytic enzymes are proteases responsible for cleavage of fibrin mesh in thrombus clots, which are the primary causative agents in cardiovascular diseases. Developing safe, effective and cheap thrombolytic agents are important for prevention and cure of thrombosis. Although a wide variety of sources have been discovered for fibrinolytic enzymes, only few of them have been employed in clinical and therapeutic applications due to the drawbacks such as high cost of production, low stability of enzyme or therapeutic side effects. However, the discovery of new fibrinolytic enzymes requires complex purification stages and characterization, which gives an insight into their diverse modes of action. Post-discovery, approaches such as a) statistical optimization for fermentative bioprocessing and b) genetic engineering are advantageous in providing economic viability by finding simple and cost-effective medium, strain development with sufficient nutrient supplements for stable and high-level production of recombinant enzyme. This review provides a comprehensive understanding of different sources, purification techniques, production through genetic engineering approaches and statistical optimization of fermentation parameters as proteases have a wide variety of industrial and biotechnological applications making 60% of total enzyme market worldwide. New strategies targeting increased enzyme yields, non-denaturing environments, improved stability, enzyme activity and strain improvement have been discussed.

Abstract
The fibrinolytic activity in Korean traditional fermented food, Jotgal (pickled fish) was identified. Though the fibrinolytic activity could vary in different kinds of Jotgal, this activity seems to be produced by microorganisms during the natural fermentation stage. From Gonjaengijot (pickled opossum shrimp), two novel fibrinolytic enzymes named by JP-I and JP-II, have been purified by ethanol precipitation, Bio-GEL P-100 gel filtration, and DEAE-cellulose ion-exchange chromatography. Compared to the crude enzyme extract, the specific activity of the JP-I and JP-II increased 258, 85-fold with the recovery of 22.1, 8.5%, respectively. The molecular weights of both enzymes were estimated as 36 kDa on sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE). The optimal condition for fibrinolytic activity of JP-I was at 50°C and pH 8.1, while that of JP-II was at 45°C and 9.9. Both enzymes were stable at a broad range of pH (5.0 to 10.5) and have metalloprotease nature. From these results, it concludes that these enzymes could be a novel potent thrombolytic agent. PRACTICAL APPLICATIONS: The fibrinolytic enzyme is one of the clinical agents for cardiovascular diseases which is the leading cause of morbidity and mortality worldwide with 17 million deaths every year. A variety of fibrinolytic enzymes are found and characterized from various sources such as plants, animals, and microorganisms, and new sources for fibrinolytic enzymes continue to be explored. Jotgal, widely used in Korean people's diet, is a traditional Korean seafood prepared from many different types of fishes, fish eggs, fish intestines, and shellfishes. Through an amount of research, some of fibrinolytic enzymes were found and purified from Jotgal, however, no studies have been done on fibrinolytic enzyme from opossum shrimp. In this study, the purification, enzymatic characteristics, and fibrinolytic activity of the proteases, originated from Korean traditional fermented food, Jotgal were reported. These enzymes could be novel potent thrombolytic agent.

Front Immunol 2017; 8:666. [PMID: 28713364 PMCID: PMC5492111 DOI: 10.3389/fimmu.2017.00666] [Citation(s) in RCA: 48] [Impact Index Per Article: 6.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2016] [Accepted: 05/22/2017] [Indexed: 12/22/2022] Open
Abstract
A single-band protein (HEP3) was isolated from Hericium erinaceus using a chemical separation combined with pharmacodynamic evaluation methods. This protein exhibited immunomodulatory activity in lipopolysaccharide-activated RAW 264.7 macrophages by decreasing the overproduction of tumor necrosis factor-α, interleukin (IL)-1β, and IL-6, and downregulating the expression of inducible nitric oxide synthase and nuclear factor-κB p65. Further researches revealed that HEP3 could improve the immune system via regulating the composition and metabolism of gut microbiota to activate the proliferation and differentiation of T cells, stimulate the intestinal antigen-presenting cells in high-dose cyclophosphamide-induced immunotoxicity in mice, and play a prebiotic role in the case of excessive antibiotics in inflammatory bowel disease model mice. Aided experiments also showed that HEP3 could be used as an antitumor immune inhibitor in tumor-burdened mice. The results of the present study suggested that fungal protein from H. erinaceus could be used as a drug or functional food ingredient for immunotherapy because of its immunomodulatory activities.

Purification and partial characterization of a low molecular fibrinolytic serine metalloprotease C142 from the culture supernatant of Bacillus subtilis C142. Int J Biol Macromol 2017; 104:724-731. [PMID: 28600208 DOI: 10.1016/j.ijbiomac.2017.06.025] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2017] [Revised: 06/01/2017] [Accepted: 06/05/2017] [Indexed: 11/20/2022]
Abstract
Novel serine metalloprotease-like enzyme, C142 was purified from the culture supernatant of Bacillus subtilis C142. The C142 was purified to homogeneity by a two-step procedure with a 20.7-fold increase in specific activity and 0.9% recovery. The molecular mass of C142 was approximately 23.5kDa based on SDS-PAGE. The N-terminal amino acid sequence of the first 21 amino acids of C142 was AQSVPYGISQIKAPALHSQGY. Its optimum pH, optimum temperature, pH stability, and thermal stability were pH 6, 40°C, pH 6-8, and 20-35°C, respectively. C142 was strongly inhibited by PMSF and EGTA, suggesting that C142 was a serine metalloprotease-like enzyme. C142 showed the highest specificity toward the substrate for t-PA. The apparent Km, Vmax, and Kcat values of C142 toward H-d-Ile-Pro-Arg-pNA were determined as 0.34mM, 0.25mmolmg-1min-1, and 46.83s-1. C142 exhibited fibrinolytic activity, which is stronger than that of plasmin. C142 hydrolyzed Aα, and Bβ-chains of fibrinogen, but did not cleave γ-chains. C142 had antithrombotic effect in three animal models. C142 was devoid of hemorrhagic activity at a dose of 20,000FU/kg. Taken together, our results indicate that B. subtilis C142 produces a serine metalloprotease-like enzyme/fibrinolytic enzyme and this enzyme might be used as a new thrombolytic agent.

Abstract
The characterization of a novel protease from Amanita virgineoides is described. The A. virgineoides protease was purified to homogeneity using Q-Sepharose, carboxymethyl-cellulose, diethylaminoethyl-cellulose, and a gel filtration step on Superdex 75. The molecular mass of the purified protease was estimated to be 16.6 kDa. The protease was purified 32.1-fold, and its specific activity was 301.4 U/mg. The optimum pH was 4.0, and the optimum temperature was 50 °C. Kinetic constants (Km , Vmax ) were determined under the optimum reaction conditions, with Km and Vmax , being 3.74 mg/mL and 9.98 μg mL-1 Min-1 , respectively. The activity of the protease was curtailed by Cu2+ , Pb2+ , Fe3+ , Cd2+ , and Hg2+ ions but enhanced by Mg2+ , Ca2+ , and K+ ions at low concentrations. The protease activity was adversely affected by ethylene diamine tetraacetic acid, suggesting that it is a metalloprotease. Four peptide sequences were obtained from liquid chromatography-tandem mass spectrometry, including KQALSGIR, TIAMDGTEGLVR, VALTGLTVAEYFR, and AGAGSATLSMAYAGAR, which showed 86%, 64%, 60%, and 75% identity with peptides of Hypsizygus marmoreus, Dacryopinax sp. DJM-731 SS1, Trametes versicolor FP-101664 SS1, and Paxillus involutus ATCC 200175, respectively. The newly isolated protease showed good hydrolytic activity and biochemical characteristics, which expanded the knowledge of biologically active proteins and provided further insight on this poisonous fungus.

Abstract
The present investigation highlights the optimal conditions for production of a non-toxic, bi-functional fibrinolytic enzyme xylarinase produced by endophytic fungus Xylaria curta by solid substrate fermentation using rice chaff medium. The purified enzyme is a monomeric protein with a molecular mass of ∼33 kDa. The enzyme exhibits cleavage of Aα and Bβ chains of fibrin(ogen) and has no effect on γ chain. The optimal fibrinolytic activity of the enzyme was observed at 35 °C and pH 8. The fibrinolytic activity was enhanced in the presence of Ca2+, whereas it was completely inhibited in the presence of Fe2+ and Zn2+ ions and inhibitors like EDTA and EGTA suggesting it to be a metalloprotease. The K m and V max of the enzyme for azocasein were 326 μM and 0.13 μM min-1. The N-terminal sequence of the enzyme (SNGPLPGGVVWAG) was same when compared to xylarinase isolated from culture broth of X. curta. Thus, xylarinase could be exploited as a potent clot busting enzyme which could be produced on large scale using solid substrate fermentation.

Abstract
Cost-effective, fibrinolytic agents possessing least or no antigenic properties are much in demand for their prospective use as clot busters in thrombolytic therapy. The present communication explores the potential of 22 endophytic Botryosphaeria species isolated from stem of Aegle marmelos for their fibrinolytic potential. Only nine fungal isolates exhibited proteolytic activity out of which only four possessed plasminogen-independent fibrinolytic activity. The endophytic fungal isolate #1088 AMSTITYEL showed maximum in vitro proteolytic and fibrinolytic activity with a halo formation of 153.86 and 113.04 mm2, respectively. The partially purified protein exhibited a fibrinolytic activity equivalent to 6.51 U/ml of plasmin. SDS-PAGE of the dialysed fraction of #1088 AMSTITYEL resolved into six bands ranging from 26 to 80 kDa. Fibrin zymogram exhibited that a single band of molecular size ~80 KDa possessing the fibrinolytic activity. Furthermore, the bioactive isolate #1088 AMSTITYEL was identified as Lasiodiplodia pseudotheobromae using classical and molecular taxonomic tools.

Abstract
Environmentally acceptable disposal of olive cultivation residues (e.g., olive prunings; olive pruning residues (OLPR)) and olive mill wastes is of paramount importance since they are generated in huge quantities within a short time. Moreover, olive mill wastewater (OMW) or sludge-like effluents ("alperujo"; two-phase olive mill waste (TPOMW)) are highly biotoxic. Hericium erinaceus is a white-rot fungus which produces choice edible mushrooms on substrates rich in lignocellulosics, and its suitability for the treatment of olive by-products was examined for the first time. Fungal growth resulted in a notable reduction of OMW's pollution parameters (i.e., 65 % decolorization, 47 % total phenolic reduction, and 52 % phytotoxicity decrease) and correlated with laccase and manganese peroxidase activities. Solid-state fermentation of various mixtures of OLPR, TPOMW, and beech sawdust (control) by H. erinaceus qualified OLPR in subsequent cultivation experiments, where it exhibited high mushroom yields and biological efficiency (31 %). Analyses of proximate composition and bioactive compound content revealed that mushrooms deriving from OLPR substrates showed significantly higher crude fat, total glucan, β-glucan, total phenolics, and ferric-reducing antioxidant potential values than the control. H. erinaceus demonstrated the potential to detoxify OMW and bioconvert OLPR into high-quality biomass, and hence, this fungus could be successfully exploited for the treatment of such by-products.

Abstract
Hericium erinaceus (H. erinaceus) is a source of exogenous antioxidants that has been traditionally used in China for the prevention and treatment of oxidative stress-associated disease. In the present study, the bioactive compounds of H. erinaceus were extracted with the following eight representative reagents: n-Hexane, xylene, chloroform, anhydrous ether, ethyl acetate, acetone, anhydrous ethanol and distilled water. The in vitro antioxidant activities were also evaluated. All of the extracted compounds exhibited reducing power and scavenging activity against 1-diphenyl-2-picrylhydrazyl (DPPH) and superoxide anion free radicals. In addition, the antioxidant capacities varied with the used chemical reagents and exhibited dose-dependent effects. Extracts from anhydrous ethanol, chloroform and acetone were capable of inhibiting lipid peroxidation. The anhydrous ethanol extracts were observed to have significant levels of antioxidant compounds since they had a strong reducing power, high scavenging rates against DPPH and superoxide anion-free radicals (>90%), and high inhibition rates on lipid peroxidation (>60%). The present study will provide reference data for the antioxidant applications of H. erinaceus in pharmaceutical use and disease prevention.

Abstract
Xylarinase is a bi-functional fibrinolytic metalloprotease isolated from the culture filtrate of endophytic fungus Xylaria curta which is monomeric with a molecular mass of ∼33.76 kDa. The enzyme displayed both plasmin and tissue plasminogen activator like activity under in vitro conditions. It hydrolyses Aα and Bβ chains of the fibrinogen. Optimal fibrinolytic activity of xylarinase is observed at 35 °C, pH 8. Ca(2+) stimulated the fibrinolytic activity of xylarinase while Fe(2+) and Zn(2+) inhibited suggesting it to be a metalloprotease. The Km and Vmax values of xylarinase were 240.9 μM and 1.10 U/ml for fibrinogen and 246 μM and 1.22 U/ml for fibrin, respectively. Xylarinase was found to prolong the activated partial thromboplastin time and prothrombin time. The N-terminal sequence of xylarinase (SNGPLPGGVVWAG) did not show any homology with previously known fibrinolytic enzymes. Thus xylarinase is a novel fibrinolytic metalloprotease which could be possibly used as a new clot busting enzyme.

Abstract
A novel protease, named PSLTro01, with fibrinolytic and anticoagulant activity was isolated from Porcellio scaber Latreille and was purified by a combination of hollow fibre membrane molecular weight cut-off (MWCO), ammonium sulfate fractionation, gel filtration and ion-exchange chromatography. PSLTro01 is a single-chain protein with a molecular mass of 38,497 Da as estimated by non-reduced SDS-PAGE and MALDI-TOF MS spectrometry, and its N-terminal 15 amino acid sequence was determined as DINGGGATLPQPLYQ. PSLTro01 is stable in the range of 20-40 °C and pH 6.0-10.0, with a maximum fibrinolytic activity at 40 °C and pH 7.0. The PSLTro01-induced fibrinolytic activity was not influenced by K(+) or Na(+) but was slightly increased by Mg(2+) and completely inhibited by aprotinin and pepstatin A. Fibrin plate assays revealed that PSLTro01 could not directly degrade fibrin but was a plasminogen activator. PSLTro01 exhibited high specificity for the substrate S-2251 for plasmin, followed by S-2238 for thrombin and S-2444 for urokinase. Moreover, the fibrinogenolysis pattern of PSLTro01 was Aα-chains>Bβ-chains>γ-chain. Tail-thrombus of the enzyme treated group was significantly shorter than the physiological saline treated group and the thrombus decrement was correlated with the enzyme dose. PSLTro01 prolongs both thrombin time (TT) and activated partial thromboplastin time (APTT). These results indicate that PSLTro01 may have potential applications in the prevention and treatment of thrombosis.

Abstract
Arenicola cristata, a marine annelid, is a well-known and prized traditional Chinese medicine. However, the serine protease gene of A. cristata has not been cloned yet. In this study, a novel protease of A. cristata was cloned, sequenced, and expressed in Escherichia coli, and the functions of this recombinant protease were also investigated. The whole complementary DNA (cDNA) of this novel protease was of 980 bp in length and consisted of an open reading frame of 861 bp encoding 286 aa. Sequence analysis of the deduced amino acid sequence revealed that the protease belongs to the serine protease family. The active enzyme of the proposed A. cristata protease is composed of a signal peptide, a propeptide, and a mature polypeptide. The molecular weight of the recombinant mature protein was ~26 kDa after over-expression in E. coli. The recombinant protein significantly inhibited cell growth and induced cell apoptosis of esophageal squamous cell carcinoma (ESCC) in vitro, and reduced tumorigenicity in vivo. Furthermore, administration of the recombinant protein led to the activation of caspase-9 as well as down-regulation of Mcl-1 and Bcl-2. Taken together, our findings indicated that the recombinant serine protease of A. cristata could inhibit ESCC cell growth by mitochondrial apoptotic pathway and might act as a potential pharmacological agent for ESCC therapy.

Honda with anticoagulant activity: purification and partial characterization. J Biosci Bioeng 2014; 118:372-7. [PMID: 24746735 DOI: 10.1016/j.jbiosc.2014.03.004] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2014] [Revised: 02/26/2014] [Accepted: 03/09/2014] [Indexed: 01/29/2023]
Abstract
A thrombolytic protease named kitamase possessing anticoagulant property was purified from edible and medicinal plant Aster yomena (Kitam.) Honda. Kitamase showed a molecular weight of 50 kDa by SDS-PAGE and displayed a strong fibrin zymogram lysis band corresponding to the similar molecular mass. The enzyme was active at high temperatures (50°C). The fibrinolytic activity of kitamase was strongly inhibited by EDTA, EGTA, TPCK and PMSF, inhibited by Zn(2+). The Km and Vmax values for substrate S-2251 were determined as 4.31 mM and 23.81 mM/mg respectively. It dissolved fibrin clot directly and specifically cleaved the α, Aα and γ-γ chains of fibrin and fibrinogen. In addition, kitamase delayed the coagulation time and increased activated partial thromboplastin time and prothrombin time. Kitamase exerted a significant protective effect against collagen and epinephrine induced pulmonary thromboembolism in mice. These results suggest that kitamase may have the property of metallo-protease like enzyme, novel fibrino(geno)lytic enzyme and a potential to be a therapeutic agent for thrombosis.
