ID 2.1.1.309 DE 18S rRNA (guanine(1575)-N(7))-methyltransferase. AN 18S rRNA methylase Bud23. CA guanosine(1575) in yeast 18S rRNA + S-adenosyl-L-methionine = N(7)- CA methylguanosine(1575) in yeast 18S rRNA + S-adenosyl-L-homocysteine. CC -!- The enzyme, found in eukaryotes, is involved in pre-rRNA processing. CC -!- The numbering corresponds to the enzyme from the yeast Saccharomyces CC cerevisiae.
