Function

function

Specifically methylates position 2 of adenine 2503 in 23S rRNA and position 2 of adenine 37 in tRNAs.

Miscellaneous

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

Catalytic activity

Cofactor

[4Fe-4S] cluster (UniProtKB | Rhea| CHEBI:49883 )

Note: Binds 1 [4Fe-4S] cluster. The cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine.
