Abstract
The nucleotide sequence of the unusual plasmid-mediated OXA2 beta-lactamase is presented, and compared with other beta-lactamases. The OXA2 enzyme has similar features at the presumed active site, but no other significant regions of homology with other penicillin-reactive enzymes. The active site homology may therefore represent convergent evolution of otherwise dissimilar genes.
摘要
呈现了异常的质粒介导的OXA2β-内酰胺酶的核苷酸序列，并与其他β-内酰胺酶进行了比较。OXA2酶在假定的活性位点具有相似的特征，但与其他青霉素反应性酶没有其他显著的同源区域。因此，活性位点的同源性可能代表了其他不同基因的趋同进化。
