CC -!- FUNCTION: Catalyzes the 2'-O methylation of guanosine at position 18 in
CC tRNA. {ECO:0000256|HAMAP-Rule:MF_02060}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=guanosine(18) in tRNA + S-adenosyl-L-methionine = 2'-O-
CC methylguanosine(18) in tRNA + H(+) + S-adenosyl-L-homocysteine;
CC Xref=Rhea:RHEA:20077, Rhea:RHEA-COMP:10190, Rhea:RHEA-COMP:10192,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789,
CC ChEBI:CHEBI:74269, ChEBI:CHEBI:74445; EC=2.1.1.34;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_02060};
CC -!- SIMILARITY: Belongs to the class IV-like SAM-binding methyltransferase
CC superfamily. RNA methyltransferase TrmH family. {ECO:0000256|HAMAP-
CC Rule:MF_02060}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_02060}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
