To capture a state of the enzyme in complex with an intact substrate, we developed and adopted a novel freezing method in crystal preparation procedure. Neither the elimination of the catalytically indispensable ligands, nor mutation or modification of the active site is required. At -20 degrees C,

During the past thirty years significant contributions to our understanding of the structural origins of the catalytic power of enzymes have come from solution and crystallographic studies of enzyme-substrate and enzyme-intermediate complexes trapped at subzero temperatures, a field that was pioneer
Three decades of the class A beta-lactamase acyl-enzyme.

The discovery that the mechanism of beta-lactam hydrolysis catalyzed by the class A (active site serine-dependent) beta-lactamases proceeds via an acyl-enzyme intermediate was made thirty years ago. Since this discovery, the active site circumstance that enables acylation of the active site serine a
… Finally, we introduce "X-ray cryoenzymology" or "low temperture protein crystallography", the apparently most effective technique for determining the details of the interaction of enzymes with their actual substrates, which will be a popular method in no distant future. …
