CC -!- FUNCTION: Methyltransferase that catalyzes the formation of N(7)-
CC methylguanine at position 46 (m7G46) in tRNA, a modification required
CC to maintain stability of tRNAs; its absence resulting in tRNA decay.
CC Both the D-stem and T-stem structures of tRNAs are required for
CC efficient methyltransferase activity. {ECO:0000256|HAMAP-
CC Rule:MF_03055}.
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_03055};
CC -!- PATHWAY: tRNA modification; N(7)-methylguanine-tRNA biosynthesis.
CC {ECO:0000256|HAMAP-Rule:MF_03055}.
CC -!- SUBUNIT: Forms a complex with TRM82. {ECO:0000256|HAMAP-Rule:MF_03055}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000256|HAMAP-Rule:MF_03055}.
CC -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC superfamily. TrmB family. {ECO:0000256|HAMAP-Rule:MF_03055}.
