Abstract

This study will 1). solve the structure of a novel (+) gamma lactamase enzyme from a Comomonas acidovorans species. This enzyme is related to a group of proteins that include acetamidase and formamidase; no structural information is currently available for any member of this group; 2). solve the structure of substrate and inhibitor complexes of the enzyme to understand the overall mechanism; 3). characterise active site mutants of the enzyme in regard to their activity and substrate specificity; and 4). initiate structural studies and characterise an unrelated (-) gamma lactamase enzyme from Aureobacterium species that has opposite stereoselectivity for the lactam substrate and shows sequence homology to non-cofactor containing haloperoxidases.
