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 (By similarity). {ECO:0000250}.
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   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the RNA methyltransferase RsmE family.
CC       {ECO:0000305}.
