Function

function

Specifically methylates position 2 of adenine 2503 in 23S rRNA and position 2 of adenine 37 in tRNAs. m2A2503 modification seems to play a crucial role in the proofreading step occurring at the peptidyl transferase center and thus would serve to optimize ribosomal fidelity.

Miscellaneous

Reaction proceeds by a ping-pong mechanism involving intermediate methylation of a conserved cysteine residue.

Caution

Lacks conserved residue(s) required for the propagation of feature annotation.
The sequence shown here is derived from an EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is preliminary data.
