FUNCTIONSpecifically methylates the pseudouridine at position 1915 (m3Psi1915) in 23S rRNA.
CATALYTIC ACTIVITY Reaction=pseudouridine(1915) in 23S rRNA + S-adenosyl-L-methionine = H(+) + N(3)-methylpseudouridine(1915) in 23S rRNA + S-adenosyl-L- homocysteine; Xref=Rhea:RHEA:42752, Rhea:RHEA-COMP:10221, Rhea:RHEA- COMP:10222, ChEBI:CHEBI:15378, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789, ChEBI:CHEBI:65314, ChEBI:CHEBI:74486; EC=2.1.1.177;
case <OC:Bacteria>
SUBUNITHomodimer.
end case
SUBCELLULAR LOCATIONCytoplasm.
SIMILARITYBelongs to the RNA methyltransferase RlmH family.
