  • The cdna sequence with 789 bp encodes an uncompleted open reading frame ( orf ) of 263 amino acids , which included a signal peptide of 18 amino acids , a proposed propeptide of 171 amino acids , a partial mature protein of 74 amino acids . the sequences of signal peptide and propeptide are very similar to ones from wannan agkistrodon acutus reported by fan chunyan , but it only contains partial amino acids of mature protein . the 800 bp is likely to be a part of gene encoding metalloproteinase agkistrodon acutus from guangxi province
    结论: 600bp产物和已报道的皖南五步蛇纤溶酶金属蛋白酶氨基酸序列相比较,有90 . 6 %的同源性; 800bp产物中信号肽及前肽和已报道的皖南五步蛇金属蛋白酶很相似,同源性为97 . 9 % ,但仅含有部分金属蛋白酶成熟肽的氨基酸序列,推测此片段为广< wp = 6 >西五步蛇金属蛋白酶原基因的一部分。
