General annotation (Comments)
| 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 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. |
