-
Dihydroprymidine dehydrogenase catalyzes the first and rate-limiting step, in pyrimidine degradation by converting pyrimidines to the corresponding, 5,6- dihydro compounds. The three-dimensional structures of a binary, complex with the inhibitor 5-iodouracil and two ternary complexes with, NADPH and the inhibitors 5-iodouracil and uracil-4-acetic acid were, determined by x-ray crystallography. In the ternary complexes, NADPH is, bound in a catalytically competent fashion, with the nicotinamide ring in, a position suitable for hydride transfer to FAD. The structures provide a, complete picture of the electron transfer chain from NADPH to the, substrate, 5-iodouracil, spanning a distance of 56 A and involving FAD, four [Fe-S] clusters, and FMN as cofactors. The crystallographic analysis, ... [[http://ispc.weizmann.ac.il/pmbin/getpm?11796730 (full description)]]
