GAMMA LACTAMASE FROM AN AUREOBACTERIUM SPECIES IN COMPLEX WITH 3A,4,7,7A-TETRAHYDRO-BENZO [1,3] DIOXOL-2-ONE
Overview
The structure of the recombinant (-) gamma-lactamase from an, Aureobacterium species has been solved at 1.73A resolution in the cubic, space group F23 with unit cell parameters a=b=c=240.6A. The trimeric, enzyme has an alpha/beta hydrolase fold and closely resembles the cofactor, free haloperoxidases. The structure has been solved in complex with a, covalently bound ligand originating from the host cell and also in the, unligated form. The associated density in the former structure has been, interpreted as the two-ring ligand (3aR,7aS)-3a,4,7,7a-tetrahydro-benzo, [1,3] dioxol-2-one which forms a tetrahedral complex with OG of the, catalytic Ser98. Soaks of these crystals with the industrial substrate, gamma-lactam or its structural analogue, norcamphor, result in the, displacement of the ... [(full description)]
