摘要: 根据芽孢杆菌(Bacillus)胶原蛋白酶基因序列保守区域设计一对兼并引物,采用PCR法获得胶原蛋白酶产生菌短小芽孢杆菌(B. pumilus)Col-J株胶原蛋白酶基因保守片段。序列分析表明,该片段与枯草芽孢杆菌(B. subtilis)基因组序列AL009126中编码胶原蛋白酶基因序列高度同源。参考该序列,获得了短小芽孢杆菌Col-J株胶原蛋白酶基因全长开放阅读框序列。序列分析及生物信息学分析表明,该基因长930bp,推测为编码含309个氨基酸残基的胶原蛋白酶基因cola,理论分子量47.63kDa,为非分泌性蛋白,仅有1个潜在的N-糖基化位点,密码子使用具有明显的偏爱性。

Abstract: According to the conserved regions of Bacillus collagenase gene, a pair of degenerate primer was designed to amplify collagenase gene fragment from B. pumilus strain Col-J with collagenolytic activity.Sequence analysis showed that the fragment sequence was highly homologous to a sequence encoding collagenase in the genome of B. subtilis AL009126 in GenBank.Based on the sequence, the collagenase gene full-length open reading frame cola was obtained from B. pumilus Col-J strain.Sequence and bioinformatics analysis showed that it was 930 bp in length, presumably encoded a collagenase with 309 amino acid residues with 47.63 kDa theoretically.Furthermore, its encoding protein was a non-secreted protein with only one potential N-glycosylation site, and showed a strong usage bias.

Key words: Bacillus pumilus, collagenase, gene cloning, sequence analysis
