Comments [?]

Function Methyltransferase involved in ribosomal biogenesis. Specifically catalyzes the N1-methylation of the pseudouridine corresponding to position 914 in M.jannaschii 16S rRNA.
Catalytic activity RHEA:46696: a pseudouridine in 16S/18S rRNA + S-adenosyl-L-methionine = an N(1)-methylpseudouridine in 16S/18S rRNA + H(+) + S-adenosyl-L-homocysteine
Subunit Homodimer.
Similarity Belongs to the class IV-like SAM-binding methyltransferase superfamily. RNA methyltransferase NEP1 family.
