IUBMB Enzyme Nomenclature

EC 2.1.1.309

Accepted name: 18S rRNA (guanine1575-N7)-methyltransferase

Reaction: S-adenosyl-L-methionine + guanine1575 in 18S rRNA = S-adenosyl-L-homocysteine + N7-methylguanine1575 in 18S rRNA

Other name(s): 18S rRNA methylase Bud23; BUD23 (gene name)

Systematic name: S-adenosyl-L-methionine:18S rRNA (guanine1575-N7)-methyltransferase

Comments: The enzyme, found in eukaryotes, is involved in pre-rRNA processing. The numbering corresponds to the enzyme from the yeast Saccharomyces cerevisiae [1].
