A new high-level gentamicin resistance gene, designated aph(2")-Ib, was cloned from Enterococcus faecium SF11770. The deduced amino acid sequence of the 897-bp open reading frame of aph(2")-Ib shares homology with the aminoglycoside-modifying enzymes AAC(6')-APH(2"), APH(2")-Ic, and APH(2")-Id. The observed phosphotransferase activity is designated APH(2")-Ib.
从屎肠球菌SF11770中克隆出一个新的高水平庆大霉素抗性基因,命名为aph(2")-Ib。aph(2")-Ib的897个碱基对开放阅读框推导的氨基酸序列与氨基糖苷修饰酶AAC(6')-APH(2")、APH(2")-Ic和APH(2")-Id具有同源性。所观察到的磷酸转移酶活性被命名为APH(2")-Ib。
