RT diatom success in the polar Southern Ocean.";
RL Submitted (SEP-2016) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Specifically methylates the N1 position of guanosine-37 in
CC various cytoplasmic and mitochondrial tRNAs. Methylation is not
CC dependent on the nature of the nucleoside 5' of the target nucleoside.
CC This is the first step in the biosynthesis of wybutosine (yW), a
CC modified base adjacent to the anticodon of tRNAs and required for
CC accurate decoding. {ECO:0000256|HAMAP-Rule:MF_03152}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=guanosine(37) in tRNA + S-adenosyl-L-methionine = H(+) + N(1)-
CC methylguanosine(37) in tRNA + S-adenosyl-L-homocysteine;
CC Xref=Rhea:RHEA:36899, Rhea:RHEA-COMP:10145, Rhea:RHEA-COMP:10147,

CC Evidence={ECO:0000256|HAMAP-Rule:MF_03152};
CC -!- SUBUNIT: Monomer. {ECO:0000256|HAMAP-Rule:MF_03152}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion matrix {ECO:0000256|HAMAP-
CC Rule:MF_03152}. Nucleus {ECO:0000256|HAMAP-Rule:MF_03152}. Cytoplasm
CC {ECO:0000256|HAMAP-Rule:MF_03152}. Note=Predominantly in the
CC mitochondria and in the nucleus. {ECO:0000256|HAMAP-Rule:MF_03152}.
CC -!- SIMILARITY: Belongs to the TRM5 / TYW2 family. {ECO:0000256|HAMAP-
CC Rule:MF_03152}.
CC -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC superfamily. TRM5/TYW2 family. {ECO:0000256|ARBA:ARBA00009775}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_03152}.
