Genes for MGH-1, YOU-1, and YOU-2 extended-spectrum beta-lactamases have been cloned and sequenced. The gene for MGH-1 has the sequence of blaTEM-10, YOU-2 has that of blaTEM-12, and YOU-1 has that of blaTEM-26. All have evolved from blaTEM-1b but have the strong dual promoter sequence of blaTEM-2.
编码MGH-1、YOU-1和YOU-2超广谱β-内酰胺酶的基因已被克隆和测序。MGH-1基因具有blaTEM-10的序列,YOU-2基因具有blaTEM-12的序列,而YOU-1基因具有blaTEM-26的序列。所有这些基因均由blaTEM-1b进化而来,但都具有blaTEM-2的强双启动子序列。
