16S rRNA (guanine1516-N2)-methyltransferase

16S rRNA (guanine-N)-methyltransferase (EC 2.1.1.242, yhiQ (gene), rsmJ (gene), m2G1516 methyltransferase) is an enzyme with systematic name S-adenosyl-L-methionine:16S rRNA (guanine-N)-methyltransferase. This enzyme catalyses the following chemical reaction

S-adenosyl-L-methionine + guanine in 16S rRNA

\rightleftharpoons

S-adenosyl-L-homocysteine + N-methylguanine in 16S rRNA

The enzyme specifically methylates guanine at N in 16S rRNA.
