CC   -!- FUNCTION: Dimethylates a single guanine residue at position 26 of a
CC       number of tRNAs using S-adenosyl-L-methionine as donor of the methyl
CC       groups. {ECO:0000255|HAMAP-Rule:MF_00290}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=guanosine(26) in tRNA + 2 S-adenosyl-L-methionine = 2 H(+) +
CC         N(2)-dimethylguanosine(26) in tRNA + 2 S-adenosyl-L-homocysteine;
CC         Xref=Rhea:RHEA:43140, Rhea:RHEA-COMP:10359, Rhea:RHEA-COMP:10360,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789,
CC         ChEBI:CHEBI:74269, ChEBI:CHEBI:74513; EC=2.1.1.216;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00290};
CC   -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC       superfamily. Trm1 family. {ECO:0000255|HAMAP-Rule:MF_00290}.
