CC -!- FUNCTION: Specifically methylates the N3 position of the uracil ring of
CC uridine 1498 (m3U1498) in 16S rRNA. Acts on the fully assembled 30S
CC ribosomal subunit. {ECO:0000256|ARBA:ARBA00025699,
CC ECO:0000256|PIRNR:PIRNR015601}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=S-adenosyl-L-methionine + uridine(1498) in 16S rRNA = H(+) +
CC N(3)-methyluridine(1498) in 16S rRNA + S-adenosyl-L-homocysteine;

CC Evidence={ECO:0000256|ARBA:ARBA00000792,
CC ECO:0000256|PIRNR:PIRNR015601};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|ARBA:ARBA00004496,
CC ECO:0000256|PIRNR:PIRNR015601}.
CC -!- SIMILARITY: Belongs to the RNA methyltransferase RsmE family.
CC {ECO:0000256|ARBA:ARBA00005528, ECO:0000256|PIRNR:PIRNR015601}.
