STRUCTURE-BASED PREDICTION OF MODIFICATIONS IN GLUTARYLAMIDASE TO ALLOW SINGLE-STEP ENZYMATIC PRODUCTION OF 7-AMINOCEPHALOSPORANIC ACID FROM CEPHALOSPORIN C
Overview
Glutarylamidase is an important enzyme employed in the commercial, production of 7-aminocephalosporanic acid, a starting compound in the, synthesis of cephalosporin antibiotics. 7-aminocephalosporanic acid is, obtained from cephalosporin C, a natural antibiotic, either chemically or, by a two-step enzymatic process utilizing the enzymes D-amino acid oxidase, and glutarylamidase. We have investigated possibilities for redesigning, glutarylamidase for the production of 7-aminocephalosporanic acid from, cephalosporin C in a single enzymatic step. These studies are based on the, structures of glutarylamidase, which we have solved with bound phosphate, and ethylene glycol to 2.5 A resolution and with bound glycerol to 2.4 A., The phosphate binds near the catalytic serine in a way that mimics ...
