CC -!- FUNCTION: Catalyzes the formation of N(7)-methylguanine at position 46
CC (m7G46) in tRNA. {ECO:0000256|HAMAP-Rule:MF_01057}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=guanosine(46) in tRNA + S-adenosyl-L-methionine = N(7)-
CC methylguanosine(46) in tRNA + S-adenosyl-L-homocysteine;
CC Xref=Rhea:RHEA:42708, Rhea:RHEA-COMP:10188, Rhea:RHEA-COMP:10189,
CC ChEBI:CHEBI:57856, ChEBI:CHEBI:59789, ChEBI:CHEBI:74269,
CC ChEBI:CHEBI:74480; EC=2.1.1.33; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_01057};
CC -!- PATHWAY: tRNA modification; N(7)-methylguanine-tRNA biosynthesis.
CC {ECO:0000256|HAMAP-Rule:MF_01057}.
CC -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC superfamily. TrmB family. {ECO:0000256|HAMAP-Rule:MF_01057}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_01057}.
