Improved purification and characterization of the OXA-2 beta-lactamase.

Abstract

An improved and scaled-up procedure has been developed for purifying the OXA-2 plasmid-mediated beta-lactamase. This has enabled us to improve the characterization of this enzyme, including a revised determination of its amino acid composition and the sequence of the N-terminal region of the protein.
