[[http://www.uniprot.org/uniprot/SYA_ECOLI SYA_ECOLI]] Catalyzes the attachment of alanine to tRNA(Ala) in a two-step reaction: alanine is first activated by ATP to form Ala-AMP and then transferred to the acceptor end of tRNA(Ala). AlaRS also incorrectly activates the sterically smaller than alanine amino acid glycine as well as the sterically larger amino acid serine. These incorrectly charged amino acids occur because the of inherent physicochemical limitations on discrimination between closely related amino acids (glycine and serine) in the charging step.<ref>PMID:12554667</ref> <ref>PMID:18723508</ref> <ref>PMID:19661429</ref> Edits incorrectly charged Ser-tRNA(Ala) and Gly-tRNA(Ala) but not incorrectly charged Ser-tRNA(Thr).<ref>PMID:12554667</ref> <ref>PMID:18723508</ref> <ref>PMID:19661429</ref> | |||
