A	PF13354	Beta-lactamase enzyme family (Beta-lactamase2)	Beta-lactamase enzyme family	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 ...
