==CRYSTAL STRUCTURE OF A MONOCLINIC FORM OF DIHYDROPTERIDINE REDUCTASE FROM RAT LIVER==
-
A binary complex of dihydropteridine reductase and NADH crystallizes in the space group C2, with a = 222.2, b = 46.5, c = 95.3 A and beta = 101.1 degrees. There are two dimers in the asymmetric unit. The structure was solved by molecular-replacement techniques and refined with 2.6 A data to a crystallographic R factor of 16.8%. Each dimer has twofold non-crystallographic symmetry and the four individual monomers in the asymmetric unit have the same overall molecular conformation.
