S-adenosyl-L-methionine:16S rRNA (guanine1405-N7)-methyltransferase
The enzyme from the antibiotic-producing bacterium Micromonospora zionensis specifically methylates guanine1405 at N7 in 16S rRNA, thereby rendering the ribosome resistant to 4,6-disubstituted deoxystreptamine aminoglycosides, which include gentamicins and kanamycins [2].
