[[ | [[https://www.uniprot.org/uniprot/SYA_PYRHO SYA_PYRHO]] 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). Edits incorrectly charged Ser-tRNA(Ala). Incorrectly charged amino acids occur because the of inherent physicochemical limitations on discrimination between closely related amino acids (Gly and Ser) in the charging step.<ref>PMID:16087889</ref> | ||
