Protein attributes

Sequence length	356 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

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. HAMAP-Rule MF_01849
Sequence similarities	Belongs to the radical SAM superfamily. RlmN family.
