Extended-spectrum beta-lactamases: structure and kinetic mechanism.
Recent years have seen an explosion in the numbers of extented spectrum class A beta-lactamases (ESBLs). The steady-state kinetic parameters for hydrolysis of beta-lactams by ESBLs is discussed in the light of what is known about the structure of these mutant enzymes.
