Critical hydrogen bonding by serine 235 for cephalosporinase activity of TEM-1 beta-lactamase.

The role of Ser-235 in the catalytic mechanism of the TEM-1 beta-lactamase has been explored by the study of a mutant enzyme in which Ser-235 has been substituted by alanine (Ala-235 mutant enzyme). A comparative kinetic analysis of both the wild-type and the Ala-235 TEM-1 enzymes revealed little ef...
