蛇毒蛋白酶是从蝮蛇蛇毒中克隆的一种新的蛇毒金属蛋白酶。该cDNA序列具有1,891个碱基对,编码477个氨基酸的开放阅读框架,其包括17个氨基酸的信号肽,加上171个氨基酸的酶原样前肽片段,200个氨基酸的金属蛋白酶结构域,16个氨基酸的间隔区和73个氨基酸的去整合素样肽。金属蛋白酶结构域包含一个保守的签名锌结合基序HEXXXHXXGXXH的催化区域和甲硫氨酸转CIM。 用8M尿素回收包涵体中的重组蛋白,采用流加稀释法进行复性,纯化后的重组蛋白具有纤溶活性和抑制血小板聚集的能力。
Ahpfibrase was a new snake venom metalloproteinase (SVMP) which was cloned from Gloydius halys. The cDNA sequence with 1,891 base pairs encodes an open reading frame of 477 amino acids which includes a 17 amino acid signal peptide, plus a 171 amino acid segment of zymogen-like propeptide, a metalloproteinase domain of 200 amino acids, a spacer of 16 amino acids, and a disintegrin-like peptide of 73 amino acids. The metalloproteinase domain contained a conserved signature zinc-binding motif HEXXHXXGXXH in the catalytic region and a methionine-turn CIM. The recombinant protein was recovered from inclusion bodies with 8 M urea and refolding was performed by fed-batch dilution method, and purified recombinant ahpfibrase showed the fibrinolytic activity and platelet aggregation–inhibition ability.
