A triple mutant in the omega-loop of TEM-1 beta-lactamase changes the substrate profile via a large conformational change and an altered general base for catalysis
This is the catalytic domain of class A beta-lactamases [1]. It is closely related to Beta-lactamase, Pfam:PF00144, the serine beta-lactamase-like superfamily, which contains the distantly related Pfam:PF00905 and PF00768 D-alanyl-D-alanine carboxype ...
