EC 2.1.1.172     
Accepted name: 16S rRNA (guanine1207-N2)-methyltransferase
Reaction: S-adenosyl-L-methionine + guanine1207 in 16S rRNA = S-adenosyl-L-homocysteine + N2-methylguanine1207 in 16S rRNA
Other name(s): m2G1207 methyltransferase
Systematic name: S-adenosyl-L-methionine:16S rRNA (guanine1207-N2)-methyltransferase
Comments: The enzyme reacts well with 30S subunits reconstituted from 16S RNA transcripts and 30S proteins but is almost inactive with the corresponding free RNA [1]. The enzyme specifically methylates guanine1207 at N2 in 16S rRNA.
