Superfamily Vaccinia Virus protein VP39
Functional Family probable 18S rRNA (Guanine-N(7))-methyltransferase

Enzyme Information

2.1.1.309
18S rRNA (guanine(1575)-N(7))-methyltransferase.
based on mapping to UniProt P25627
S-adenosyl-L-methionine + guanine(1575) in 18S rRNA = S-adenosyl-L- homocysteine + N(7)-methylguanine(1575) in 18S rRNA.
-!- The enzyme, found in eukaryotes, is involved in pre-rRNA processing. -!- The numbering corresponds to the enzyme from the yeast Saccharomyces cerevisiae.
