Escherichia coli dihydroorotase has been crystallized in the presence of the product, L-dihydroorotate (L-DHO), and the structure refined at 1.9A resolution. The structure confirms that previously reported (PDB entry 1J79), crystallized in the presence of the substrate N-carbamyl-D,L-aspartate (D, L-CA-asp)

Dihydroorotate dehydrogenases (DHODs) oxidize dihydroorotate (DHO) to orotate using the FMN prosthetic group to abstract a hydride equivalent from C6 and a protein residue (Ser for Class 2 DHODs) to deprotonate C5. The fundamental question of whether the scission of

Mutants capable of utilizing the pyrimidine biosynthetic intermediates carbamoylaspartate and dihydroorotate for growth were derived from pyrimidine auxotrophs of Salmonella enterica serovar Typhimurium LT2. The gain-of-function phenotypes both resulted from mutations in a single gene, yhiT, the third gene of

Dihydroorotate dehydrogenases (DHODs) catalyze the only redox step in de novo pyrimidine biosynthesis, the oxidation of dihydroorotate (DHO) to orotate (OA). During the reaction, the hydrogen at C6 of DHO is transferred to N5 of the isoalloxazine ring of an
