PLP-DEPENDENT ACYL-COA SYNTHASE
Overview
8-Amino-7-oxononanoate synthase (or 8-amino-7-ketopelargonate synthase; EC, 2.3.1.47; AONS) catalyses the decarboxylative condensation of l-alanine, and pimeloyl-CoA in the first committed step of biotin biosynthesis. We, have cloned, over-expressed and purified AONS from Escherichia coli and, determined the crystal structures of the apo and PLP-bound forms of the, enzyme. The protein is a symmetrical homodimer with a tertiary structure, and active site organisation similar to, but distinct from, those of other, PLP-dependent enzymes whose three-dimensional structures are known. The, critical PLP-binding lysine of AONS is located at the end of a deep cleft, that allows access of the pantothenate arm of pimeloyl-CoA. A cluster of, positively charged residues at the entrance to this cleft ... [(full description)]
