CC Rule:MF_00074};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00074}.
CC -!- SIMILARITY: Belongs to the methyltransferase superfamily. RNA
CC methyltransferase RsmG family. {ECO:0000256|HAMAP-Rule:MF_00074}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00074}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
