Abstract
BACKGROUND Lumbrokinase derived from earthworms, Lumbricus rubellus is known to have fibrinolytic enzymes that have potential as therapeutic drugs due to its ability to dissolve fibrin. The current study is aimed to purify the Lumbrokinase from L. rubellus and identify its protein component. METHODS Water extract of local earthworm Lumbricus rubellus revealed several proteins. Therefore, to identify its protein component, purification through HiPrep DEAE fast flow and proteomic analysis were conducted prior to identifications. A combination of two-dimension gel electrophoresis (2DE) and electrospray ionization mass spectrometry analysis was used to identify the purified fractions. RESULTS The purified fractions contain five protein bands, namely F25-1, F25-2, F85-1, F85-2, and F85-3, which displayed strong fibrinogenolytic activity. F25 fractions showed fibrinogenolytic activity of 974.85 U/mg, while F85 fractions showed higher activity of 1,484.11 U/mg. Fractions F85-1, F85-2, and F85-3 showed molecular weights of 42.6 kDa, 27.03 kDa, and 14 kDa, respectively and were identified as Lumbrokinase iso-enzymes. CONCLUSION This preliminary study indicates that the F25 and F85 fractions are similar to published fibrinolytic protease-1 and lumbrokinase, respectively, in terms of their amino acid sequence.

Purification and characterization of a novel fibrinolytic enzyme from Whitmania pigra Whitman. Protein Expr Purif 2020; 174:105680. [PMID: 32497576 DOI: 10.1016/j.pep.2020.105680] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2020] [Revised: 05/02/2020] [Accepted: 05/21/2020] [Indexed: 11/22/2022]
Abstract
Developing an effective fibrinolytic drug for treating thrombolysis with minimal undesirable side effects is of great importance. In the current study, an optimum solvent was selected for the extraction of fibrinolytic active components. Furthermore, a strong fibrinolytic enzyme named WPI01 was purified from Whitmania pigra Whitman through various chromatographic steps. WPI01 has a molecular mass of 27044.297 Da, and the N-terminal 8 amino acid sequence was determined as VVGGVEAR. WPI01 was stable within the pH range of 6.0-10.0 and with maximum fibrinolytic activity at 40 °C and a pH of 8.0. At 500 U/mL, WPI01 induced 50.59% blood clot reduction in vitro within 6 h, which was higher than that induced by urokinase at 1000 U/mL. In an analysis of the plasminogen activator activity, WPI01 produced obvious halos on heated and unheated fibrin plates, suggesting that WPI01 may not only act as a plasminogen activator but also degrade fibrin clots directly, and more study is needed to support this. In conclusion, WPI01 is obviously different from known fibrinolytic enzymes in terms of substrate specificity and fibrinolytic mode of action, suggesting that it is a novel fibrinolytic enzyme with potential applications in the treatment and prevention of thrombosis.

Abstract
Intravascular thrombosis is one of the major causes of variety of cardiovascular disorders leading to high mortality worldwide. Fibrinolytic enzymes from microbial sources possess ability to dissolve these clots and help to circumvent these problems in more efficient and safer way. In the present study, fibrinolytic protease with higher fibrinolytic activity than plasmin was obtained from Serratia sp. KG-2-1 isolated from garbage dump soil. Response surface methodology was used to study the interactive effect of concentration of maltose, yeast extract + peptone (1:1), incubation time, and pH on enzyme production and biomass. Maximum enzyme production was achieved at 33 °C after 24 h at neutral pH in media containing 1.5% Maltose, 4.0% yeast extract + peptone and other trace elements resulting in 1.82 folds increased production. The enzyme was purified from crude extract using ammonium sulfate precipitation and DEAE-Sephadex chromatography resulting in 12.9 fold purification with 14.9% yield. The purified enzyme belongs to metalloprotease class and had optimal activity in conditions similar to physiological environment with temperature optima of 40 °C and pH optima of 8. The enzyme was found to be stable in various solvents and its activity was enhanced in presence of Na+, K+, Ba2+, Cu2+, Mn2+, Hg2+ but inhibited by Ca2+ and Fe3+. Hence, the obtained enzyme may be used as potential therapeutic agent in combating various thrombolytic disorders.

Abstract
A fibrinolytic enzyme was purified from the dry body of Whitmania pigra Whitman. The fibrinolytic enzyme was purified to homogeneity with a yield of 0.003% and a purification of 630.7 fold. The molecular weight of the enzyme was estimated to be 26.7 kDa by reduced sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). The enzyme was tested by matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS) and it showed that the enzyme was a novel fibrinolytic enzyme. The optimal pH and temperature of the enzyme were 8.5 and 55°C, respectively. Enzyme activity was enhanced by Na+, Mg2+, and K+. On the contrary, the proteolytic activity was significantly inhibited by Mn2+, Fe2+, Fe3+, ethylenediaminetetraacetic acid (EDTA), and ethylenebis(oxyethylenenitrilo)tetraacetic acid (EGTA). Fibrinolytic and fibrinogenolytic assays showed that the enzyme preferentially hydrolyzed fibrinogen Aα-chains, followed by Bβ- and γ-chains. The α-, β-, and γ-γ-chains of fibrin were also degraded by the enzyme.

Int J Biol Macromol 2015; 80:536-46. [PMID: 26123818 DOI: 10.1016/j.ijbiomac.2015.06.046] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2015] [Revised: 06/20/2015] [Accepted: 06/23/2015] [Indexed: 11/17/2022]
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.

Comparative proteomic analysis of the sun- and freeze-dried earthworm Eisenia fetida with differentially thrombolytic activities. J Proteomics 2013; 83:1-14.

Abstract
UNLABELLED The dried earthworm is a traditional thrombolytic medicine in East Asia. Its thrombolytic mechanism has been extensively studied. However, the effects of drying process on thrombolysis were rarely investigated. Herein, we compared the thrombolytic activity of earthworm Eisenia fetida processed by sun-drying to that by freeze-drying. Fibrin plate and blood clot lysis assays showed that freeze-dried earthworms gave dramatically higher fibrinolytic and thrombolytic activities than the sun-dried earthworms. To address the thrombolytic difference, comparative proteomic analysis was carried out using fibrin zymography and two-dimensional gel electrophoresis (2-DE). The freeze- and sun-dried earthworms generated remarkably different 2-DE protein spot patterns. A total of 126 differential protein spots were detected, 83 of them were identified by matrix-assisted laser desorption/ionization-tandem time-of-flight mass spectrometry and database searching with 13 quantitative changes and 70 qualitative changes. Five of these differential proteins were identified as fibrinolytic proteases (lumbrokinases), responsible for dissolving fibrin, the main protein component of thrombus. The total abundance of these fibrinolytic proteases in the freeze-dried earthworms was significantly higher, consistent with the results of fibrin zymography. Therefore, the higher concentration of fibrinolytic enzymes along with their broad substrate specificity explained the stronger fibrinolytic and thrombolytic activities of the freeze-dried earthworms. This study suggests that freeze-drying represents an improved processing method for earthworm as the thrombolytic therapy in the future. BIOLOGICAL SIGNIFICANCE Thrombosis has become one of the biggest concerns all over the world. The dried earthworms have been intensively used as thrombolytic agents. Its thrombotic mechanism has been studied by the modern pharmacological researches. However, the drying procedure of the earthworm and its effects on the thrombolysis were rarely investigated. The present study compared the thrombolytic effects of the freeze-dried and the normal dried earthworm E. fetida. To better understand the underlying mechanisms for differential thrombolytic effects, the fibrin zymography and the two-dimensional gel electrophoresis (2-DE) were employed to identify sets of differential proteins. Therefore, this study provides not only the comparative proteomic analysis but also molecular mechanism underlying the differential thrombolytic effects.
