Abstract excerpt

Stenotrophomonas maltophilia KH has two acid beta-lactamases with isoelectric points (pIs) of 4.6 and 5.4, and several basic beta-lactamases (pIs >7.0) that produce a ladder-shaped pattern by IEF. An isogenic L2 mutant, KHL2(xylE), was constructed by gene replacement. From IEF and native PAGE zym...
