Structural highlights

4xem is a 1 chain structure. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Ligands:,
Activity:Alanine--tRNA ligase, with EC number 6.1.1.7
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum

Disease

[SYAC_HUMAN] Autosomal dominant Charcot-Marie-Tooth disease type 2N. The disease is caused by mutations affecting the gene represented in this entry. The disease is caused by mutations affecting the gene represented in this entry.

Function

[SYAC_HUMAN] 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 tRNA(Ala) via its editing domain.[HAMAP-Rule:MF_03133]
