[https://www.uniprot.org/uniprot/RLMN_ECOLI RLMN_ECOLI] 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. Unmodified tRNA is not a suitable substrate for RlmN, which suggests that RlmN works in a late step during tRNA maturation.<ref>PMID:18025251</ref> <ref>PMID:21415317</ref> <ref>PMID:22891362</ref>
