[[http://www.uniprot.org/uniprot/SYA_AQUAE SYA_AQUAE]] 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). Also edits incorrectly charged Ser-tRNA(Ala) and Gly-tRNA(Ala) via its editing domain (By similarity).[HAMAP-Rule:MF_00036]
