THE CATALYTIC MODULE OF CEL7D FROM PHANEROCHAETE CHRYSOSPORIUM AS A CHIRAL SELECTOR: STRUCTURAL STUDIES OF ITS COMPLEX WITH THE B-BLOCKER (R)-PROPRANOLOL
Overview
Previous investigations have shown that the major cellobiohydrolase of, Phanerochaete chrysosporium, Cel7D (CBH 58), can be used to separate the, enantiomers of a number of drugs, including adrenergic beta blockers such, as propranolol. The structural basis of this enantioselectivity is, explored here. A 1.5 A X-ray structure of the catalytic domain of Cel7D in, complex with (R)-propranolol showed the ligand bound at the active site in, glucosyl-binding subsites -1/+1. The catalytic residue Glu207 makes a, strong charge-charge interaction with the secondary amine of, (R)-propranolol; this is supported by a second interaction of the amine, with the nearby Asp209. The aromatic naphthyl group stacks onto the indole, ring of Trp373 (normally the glucosyl-binding platform of subsite +1)., ... [(full description)]
