SHORT CHAIN SPECIFIC ACYL-COA OXIDASE FROM ARABIDOPSIS THALIANA, ACX4 IN COMPLEX WITH ACETOACETYL-COA
OverviewOverview
Plants produce a unique peroxisomal short chain-specific acyl-CoA oxidase, (ACX4) for beta-oxidation of lipids. The short chain-specific oxidase has, little resemblance to other peroxisomal acyl-CoA oxidases but has an, approximately 30% sequence identity to mitochondrial acyl-CoA, dehydrogenases. Two biochemical features have been linked to structural, properties by comparing the structures of short chain-specific Arabidopsis, thaliana ACX4 with and without a substrate analogue bound in the active, site to known acyl-CoA oxidases and dehydrogenase structures: (i) a, solvent-accessible acyl binding pocket is not required for oxygen, reactivity, and (ii) the oligomeric state plays a role in substrate pocket, architecture but is not linked to oxygen reactivity. The structures, indicate that ... [(full description)]
