General annotation (Comments)

Function

Methylates the class 1 translation termination release factors RF1/PrfA and RF2/PrfB on the glutamine residue of the universally conserved GGQ motif By similarity. HAMAP-Rule MF_01057

Catalyzes the formation of N(7)-methylguanine at position 46 (m7G46) in tRNA By similarity. HAMAP-Rule MF_01057

Catalytic activity

S-adenosyl-L-methionine + glutamine in release factor = S-adenosyl-L-homocysteine + N5-methylglutamine in release factor. HAMAP-Rule MF_01057

S-adenosyl-L-methionine + guanine46 in tRNA = S-adenosyl-L-homocysteine + N(7)-methylguanine46 in tRNA. HAMAP-Rule MF_01057

Sequence similarities

In the N-terminal section; belongs to the protein N5-glutamine methyltransferase family. PrmC subfamily.

In the C-terminal section; belongs to the methyltransferase superfamily. TrmB family.
