Structural superimposition of the active-site region of AtGABA-T and bacterial GABA aminotransferase homologs. The active site of AtGABA-T is superimposed with those of bacterial GABA aminotransferases from Corynebacterium glutamicum (PDB entry 6j2v) and Arthrobacter aurescens (PDB entry 4atq). Key residues involved in substrate carboxylate recognition, including the N-terminal anchoring arginine in the bacterial enzymes and the corresponding region in AtGABA-T, are shown as stick models.
