RT Streptomyces sp. ZEA17I, a biocontrol agent against plant pathogens.";
RL Submitted (MAY-2018) to the EMBL/GenBank/DDBJ databases.
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 -!- 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 -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|ARBA:ARBA00004496}.
CC -!- SIMILARITY: Belongs to the RNA methyltransferase RsmE family.
CC {ECO:0000256|ARBA:ARBA00005528}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
