IntEnz Enzyme Nomenclature


Accepted name:
16S rRNA (guanine1207-N2)-methyltransferase
Other name:
m2G1207 methyltransferase
Systematic name:
S-adenosyl-L-methionine:16S rRNA (guanine1207-N2)-methyltransferase



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.
