The phenotype of Klebsiella pneumoniae HEL-1 indicates a plasmidic cephamycinase gene (blaCMY-2). Its sequence shows one open reading frame coding for a protein of 381 amino acids. CMY-2 is classified as class C beta-lactamase that is closely related to the plasmidic enzymes BIL-1 and LAT-1 and the chromosomal AmpC of Citrobacter freundii. The blaCMY-2 gene possibly was translocated onto a plasmid of C. freundii which spread to K. pneumoniae.
肺炎克雷伯菌HEL-1的表型表明存在一个质粒头孢菌素酶基因(blaCMY-2)。其序列显示一个开放阅读框,编码一种由381个氨基酸组成的蛋白质。CMY-2被归类为C类β-内酰胺酶,与质粒酶BIL-1和LAT-1以及弗氏柠檬酸杆菌的染色体AmpC密切相关。blaCMY-2基因可能转移到了弗氏柠檬酸杆菌的一个质粒上,该质粒传播到了肺炎克雷伯菌。
