RL   Submitted (DEC-2006) to the EMBL/GenBank/DDBJ databases.
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         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}.
