| 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 | Reaction=a pseudouridine in 16S/18S rRNA + S-adenosyl-L-methionine = an N(1)-methylpseudouridine in 16S/18S rRNA + H(+) + S-adenosyl-L- homocysteine; Xref=Rhea:RHEA:46696, Rhea:RHEA-COMP:11633, Rhea:RHEA- COMP:11634, ChEBI:CHEBI:15378, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789, ChEBI:CHEBI:65314, ChEBI:CHEBI:74890; |
| SUBUNIT | Homodimer. |
| SIMILARITY | Belongs to the class IV-like SAM-binding methyltransferase superfamily. RNA methyltransferase NEP1 family. |
