TLA-2, a novel Ambler class A expanded-spectrum beta-lactamase.

ABSTRACT: Beta-lactamase TLA-2 is encoded by a 47-kb plasmid isolated from an unidentified bacterial strain from a wastewater treatment plant. TLA-2 is an Ambler class A beta-lactamase that shares 52% amino acid identity with CGA-1 from Chryseobacterium gleum and 51% with TLA-1 from Escherichia coli. The enzyme hydrolyzes mostly cephalosporins.
