CC -!- FUNCTION: Catalyzes the formation of N(7)-methylguanine at position 46
CC (m7G46) in tRNA. {ECO:0000255|HAMAP-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:0000255|HAMAP-
CC Rule:MF_03055};
CC -!- PATHWAY: tRNA modification; N(7)-methylguanine-tRNA biosynthesis.
CC {ECO:0000255|HAMAP-Rule:MF_03055}.
CC -!- SUBUNIT: Forms a complex with TRM82. {ECO:0000255|HAMAP-Rule:MF_03055}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|HAMAP-Rule:MF_03055}.
CC -!- DISRUPTION PHENOTYPE: Significant reduction in pathogenicity on the
CC host plants. Mutants develop penetration hyphae into cellophane,
CC suggesting that appressoria of the mutants retain basic function for
CC penetration. However, they fail to develop intracellular penetration
CC hyphae into epidermis of the host plants.
CC {ECO:0000269|PubMed:16556222}.
CC -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC superfamily. TrmB family. {ECO:0000255|HAMAP-Rule:MF_03055}.
CC -!- SEQUENCE CAUTION:
CC Sequence=ENH85272.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
CC Sequence=TDZ24529.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
