RT Natronomonas pharaonis.";
RL Genome Res. 15:1336-1343(2005).
CC -!- FUNCTION: Specifically dimethylates two adjacent adenosines in the loop
CC of a conserved hairpin near the 3'-end of 16S rRNA in the 30S particle.
CC May play a critical role in biogenesis of 30S subunits.
CC {ECO:0000255|HAMAP-Rule:MF_00607}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00607}.
CC -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC superfamily. rRNA adenine N(6)-methyltransferase family. RsmA
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_00607}.
