-==Overview==
+==ESCHERICHIA COLI DIHYDROOROTATE DEHYDROGENASE==
-The flavoenzymes dihydroorotate dehydrogenases (DHODs) catalyze the fourth, and only redox step in the de novo biosynthesis of UMP. Enzymes belonging, to class 2, according to their amino acid sequence, are characterized by, having a serine residue as the catalytic base and a longer N terminus. The, structure of class 2 E. coli DHOD, determined by MAD phasing, showed that, the N-terminal extension forms a separate domain. The catalytic serine, residue has an environment differing from the equivalent cysteine in class, 1 DHODs. Significant differences between the two classes of DHODs were, identified by comparison of the E. coli DHOD with the other known DHOD, structures, and differences with the class 2 human DHOD explain the, variation in their inhibitors.
