PORCINE PANCREATIC ELASTASE COMPLEXED WITH (3S, 4R)-1-TOLUENESULPHONYL-3-ETHYL-AZETIDIN-2-ONE-4-CARBOXYLIC ACID
OverviewOverview
beta-Lactam inhibitors of transpeptidase enzymes involved in cell wall, biosynthesis remain among the most important therapeutic agents in, clinical use. beta-Lactams have more recently been developed as inhibitors, of serine proteases including elastase. All therapeutically useful, beta-lactam inhibitors operate via mechanisms resulting in the formation, of hydrolytically stable acyl-enzyme complexes. Presently, it is difficult, to predict which beta-lactams will form stable acyl-enzyme complexes with, serine enzymes. Further, the factors that result in the seemingly special, nature of beta-lactams versus other acylating agents are unclear-if indeed, they exist. Here we present the 1.6 A resolution crystal structure of a, stable acyl-enzyme complex formed between porcine pancreatic ... [(full description)]
