CC -!- FUNCTION: Methylates the class 1 translation termination release
CC factors RF1/PrfA and RF2/PrfB on the glutamine residue of the
CC universally conserved GGQ motif. {ECO:0000256|HAMAP-Rule:MF_02126}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-glutaminyl-[peptide chain release factor] + S-adenosyl-L-
CC methionine = H(+) + N(5)-methyl-L-glutaminyl-[peptide chain release
CC factor] + S-adenosyl-L-homocysteine; Xref=Rhea:RHEA:42896, Rhea:RHEA-

CC ChEBI:CHEBI:30011, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789,
CC ChEBI:CHEBI:61891; EC=2.1.1.297;
CC Evidence={ECO:0000256|ARBA:ARBA00000932, ECO:0000256|HAMAP-
CC Rule:MF_02126};
CC -!- SIMILARITY: Belongs to the protein N5-glutamine methyltransferase
CC family. PrmC subfamily. {ECO:0000256|HAMAP-Rule:MF_02126}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_02126}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
