Abstract

Penicillin acylase (PA) is an enzyme of considerable industrial interest, used in the production of semi-synthetic penicillins. We have determined its 3-D crystal structure at 1.9 Angstroms resolution. This has revealed a novel mechanism for the activation of the catalytic nucleophile, the molecular basis of product inhibition and the presence of a calcium-binding site which may be important for stability and folding. This programme of research builds on this knowledge to explore and exploit some of the questions that the structure has raised regarding post-translational processing, substrate specificity and evolutionary and biochemical relationships with other proteins which have been discovered to share structural and mechanistic similarities.
