Protein

Bifunctional methyltransferase

Gene

prmC/trmB

Organism
Rickettsia conorii (strain ATCC VR-613 / Malish 7)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

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

Catalytic activityi

S-adenosyl-L-methionine + [peptide chain release factor 1 or 2]-L-glutamine = S-adenosyl-L-homocysteine + [peptide chain release factor 1 or 2]-N(5)-methyl-L-glutamine.
S-adenosyl-L-methionine + guanine(46) in tRNA = S-adenosyl-L-homocysteine + N(7)-methylguanine(46) in tRNA.
