16S rRNA (guanine(1405)-N(7))-methyltransferase.
based on mapping to UniProt Q763K9
S-adenosyl-L-methionine + guanine(1405) in 16S rRNA = S-adenosyl-L- homocysteine + N(7)-methylguanine(1405) in 16S rRNA.
-!- The enzyme from the antibiotic-producing bacterium Micromonospora zionensis specifically methylates guanine(1405) at N(7) in 16S rRNA, thereby rendering the ribosome resistant to 4,6-disubstituted deoxystreptamine aminoglycosides, which include gentamicins and kanamycins.
