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;
