STRUCTURE AND LIGAND DETERMINANTS OF THE RECOMBINANT KRINGLE 5 DOMAIN OF HUMAN PLASMINOGEN
Overview
The X-ray crystal structure of the recombinant (r) kringle 5 domain of, human plasminogen (K5HPg) has been solved by molecular replacement methods, using K1HPg as a model and refined at 1.7 A resolution to an R factor of, 16.6%. The asymmetric unit of K5HPg is composed of two molecules related, by a noncrystallographic 2-fold rotation axis approximately parallel to, the z-direction. The lysine binding site (LBS) is defined by the regions, His33-Thr37, Pro54-Val58, Pro61-Tyr64, and Leu71-Tyr74 and is occupied in, the apo-form by water molecules. A unique feature of the LBS of apo-K5HPg, is the substitution by Leu71 for the basic amino acid, arginine, that in, other kringle polypeptides forms the donor cationic center for the, carboxylate group of omega-amino acid ligands. While wild-type ... [(full description)]
