    摘要: A protease moiety having direct fibrinolytic activity which is useful in thrombolytic therapy is isolated from snake venom and shown to comprise a metalloproteinase having a molecular weight of from 25 to 27 kd and an isoelectric point of about 6.5 to 7.0. The moiety is separated from venom by a series of diverse fractionation steps including molecular sieve, ion-exchange and affinity chromatography.

    摘要: This invention relates to a new fibrinolytic substance and the method of manufacturing the same which can be singly isolated from venom of venomous snakes belonging to the family of Trimeresurus taxonomically by means of molecular sieve chromatography and ion exchange chromatography. This substance has the action of dissolving fibrin in mammals by activating plasminogen and its clinical use a fibrinolytic agent is promising.

    摘要: A NEW ONE-STEP PROCESS FOR THE PURIFICATION AND ISOLATION OF THE THROMBIN-LIKE FRACTION OF THE VENOM OF CERTAIN PIT VIPERS IS DESCRIBED. THE SIMPLE PROCESS USES AFFINITY CHROMATOGRAPHY FOR THE FRACTIONATION OF NATIVE VENOM, EMPLOYING SPECIFICALLY BUFFERED LOADING AND ELUTION SOLUTIONS. THE CHROMATOGRAPHIC COLUMN USES AN AGMATINE-COUPLED AGAROSE PACKING.

    摘要: This invention relates to methods of expressing eukaryotic proteins in prokaryotic hosts, particularly eukaryotic proteins that require formation of disulfide bridges for biological activity. Various approaches are used including fusion to thioredoxin, cytoplasmic expression of disulfide isomerases, deficiencies in thioredoxin and/or glutathione reductases, deficiencies in proteases, and the like. The method is applicable to express monomeric and dimeric forms of the eukaryotic protein with biological activity such as monomeric and dimeric forms of a disintegrin or a disintegrin domain. Included are the vectors, host cells expressing the proteins, the expressed proteins and methods of using the proteins.

    摘要: A thrombin-like enzyme isolated from Agkistrodon acutus venom, comprising an alpha subunit having the sequence of SEQ ID No. 1 and a beta subunit having the sequence of SEQ ID No. 2, which are linked by seven disulfide bonds, is provided. The hemocoagulase of Agkistrodon acutus in the present invention is a serine proteinase having a molecular weight of 29.3-29.5 kD and an isoelectric point of 5.5, and is able to hydrolyze the alpha chain of human fibrinogen. The invention also provides methods of purifying the thrombin-like enzyme from snake venom, which comprise removing insoluble substance by pretreatment, conducting twice of anion-exchange column chromatography, collecting active eluting peak, dialyzing, ultra-filtrating and desalinating so as to obtain a snake venom thrombin-like enzyme.
