THE NATIVE STRUCTURE OF A BETA-DIKETONE HYDROLASE FROM THE CYANOBACTERIUM ANABAENA SP. PCC 7120
Overview
The gene alr4455 from the well-studied cyanobacterium Anabaena sp. PCC, 7120 encodes a crotonase orthologue that displays beta-diketone hydrolase, activity. Anabaena beta-diketone hydrolase (ABDH), in common with, 6-oxocamphor hydrolase (OCH) from Rhodococcus sp. NCIMB 9784, catalyzes, the desymmetrization of bicyclo[2.2.2]octane-2,6-dione to yield, [(S)-3-oxocyclohexyl]acetic acid, a reaction unusual among the crotonase, superfamily as the substrate is not an acyl-CoA thioester. The structure, of ABDH has been determined to a resolution of 1.5 A in both native and, ligand-bound forms. ABDH forms a hexamer similar to OCH and features one, active site per enzyme monomer. The arrangement of side chains in the, active site indicates that while the catalytic chemistry may be conserved, in OCH ... [(full description)]
