Publication Abstract from PubMed
The mechanism by which class A beta-lactamase enzymes form an acyl-enzyme intermediate has been the emphasis of several studies. Here, we report on the use of neutron and high resolution X-ray diffraction to help elucidate the identity of the catalytic base in the acylation part of the mechanism.
