Comments [?]

Function Specifically methylates the pseudouridine at position 1915 (m3Psi1915) in 23S rRNA.
Catalytic activity RHEA:42752: pseudouridine(1915) in 23S rRNA + S-adenosyl-L-methionine = H(+) + N(3)-methylpseudouridine(1915) in 23S rRNA + S-adenosyl-L-homocysteine
EC 2.1.1.177
case <OC:Bacteria>
Subunit Homodimer.
end case
Subcellular location Cytoplasm.
Similarity Belongs to the RNA methyltransferase RlmH family.
