RC STRAIN=AK37; RA Kriszt B., Tancsics A., Cserhati M., Toth A., Nagy I., Horvath B., RA Tamura T., Kukolya J., Szoboszlay S.; RL Submitted (DEC-2011) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Specifically methylates position 2 of adenine 2503 in CC 23S rRNA and position 2 of adenine 37 in tRNAs (By similarity). CC -!- CATALYTIC ACTIVITY: 2 S-adenosyl-L-methionine + adenine(2503) in CC 23S rRNA = S-adenosyl-L-homocysteine + L-methionine + 5'- CC deoxyadenosine + 2-methyladenine(2503) in 23S rRNA. CC -!- CATALYTIC ACTIVITY: 2 S-adenosyl-L-methionine + adenine(37) in CC tRNA = S-adenosyl-L-homocysteine + L-methionine + 5'- CC deoxyadenosine + 2-methyladenine(37) in tRNA. CC -!- COFACTOR: Binds 1 4Fe-4S cluster. The cluster is coordinated with CC 3 cysteines and an exchangeable S-adenosyl-L-methionine (By CC similarity). CC -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity). CC -!- MISCELLANEOUS: Reaction proceeds by a ping-pong mechanism CC involving intermediate methylation of a conserved cysteine residue CC (By similarity). CC -!- SIMILARITY: Belongs to the radical SAM superfamily. RlmN family. CC -!- CAUTION: The sequence shown here is derived from an CC EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is CC preliminary data.
