CC   -!- FUNCTION: Methyltransferase involved in ribosomal biogenesis.
CC       Specifically catalyzes the N1-methylation of the pseudouridine
CC       corresponding to position 914 in M.jannaschii 16S rRNA.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a pseudouridine in rRNA + S-adenosyl-L-methionine = an N(1)-
CC         methylpseudouridine in rRNA + H(+) + S-adenosyl-L-homocysteine;

CC   -!- SUBUNIT: Homodimer.
CC   -!- SIMILARITY: Belongs to the class IV-like SAM-binding methyltransferase
CC       superfamily. RNA methyltransferase NEP1 family.
