General annotation (Comments)

Function

Specifically methylates position 2 of adenine 2503 in 23S rRNA and position 2 of adenine 37 in tRNAs By similarity. HAMAP-Rule MF_01849

Catalytic activity

2 S-adenosyl-L-methionine + adenine(2503) in 23S rRNA = S-adenosyl-L-homocysteine + L-methionine + 5'-deoxyadenosine + 2-methyladenine(2503) in 23S rRNA. HAMAP-Rule MF_01849

2 S-adenosyl-L-methionine + adenine37 in tRNA = S-adenosyl-L-homocysteine + L-methionine + 5'-deoxyadenosine + 2-methyladenine37 in tRNA. HAMAP-Rule MF_01849

Cofactor

Binds 1 4Fe-4S cluster. The cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine By similarity.

Subcellular location

Cytoplasm Potential HAMAP-Rule MF_01849.

Miscellaneous

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

Sequence similarities

Belongs to the radical SAM superfamily. RlmN family.
