Abstract

We cloned, expressed, and purified the Escherichia coli YggH protein and show that it catalyzes the S-adenosyl-L-methionine-dependent formation of N(7)-methylguanosine at position 46 (m(7)G46) in tRNA. Additionally, we generated an E. coli strain with a disrupted yggH gene and show that the mutant strain lacks tRNA (m(7)G46) methyltransferase activity.

摘要

我们克隆、表达并纯化了大肠杆菌YggH蛋白,结果表明它催化了tRNA中第46位的N(7)-甲基鸟苷(m(7)G46)的S-腺苷-L-甲硫氨酸依赖性形成。此外,我们构建了一个yggH基因被破坏的大肠杆菌菌株,并表明该突变菌株缺乏tRNA(m(7)G46)甲基转移酶活性。
