SEC-TID: A Label-Free Method for Small-Molecule Target Identification.

J. Biomol. Screen. 19(6) , 917-927, (2014)

Bioactive small molecules are an invaluable source of therapeutics and chemical probes for exploring biological pathways. Yet, significant hurdles in drug discovery often come from lacking a comprehensive view of the target(s) for both early tool molecules an...

The structures of human dihydroorotate dehydrogenase with and without inhibitor reveal conformational flexibility in the inhibitor and substrate binding sites.

Biochemistry 47(34) , 8929-36, (2008)

Inhibitors of dihydroorotate dehydrogenase (DHODH) have been suggested for the treatment of rheumatoid arthritis, psoriasis, autoimmune diseases, Plasmodium, and bacterial and fungal infections. Here we present the structures of N-terminally truncated (residu...

Miller (Genee-Wiedemann) syndrome represents a clinically and biochemically distinct subgroup of postaxial acrofacial dysostosis associated with partial deficiency of DHODH.

Hum. Mol. Genet. 21(18) , 3969-83, (2012)

Biallelic mutations in the gene encoding DHOdehase [dihydroorotate dehydrogenase (DHODH)], an enzyme required for de novo pyrimidine biosynthesis, have been identified as the cause of Miller (Genée-Weidemann or postaxial acrofacial dysostosis) syndrome (MIM 2...

Biochemical and molecular characterization of the pyrimidine biosynthetic enzyme dihydroorotate dehydrogenase fromToxoplasma gondii

Mol. Biochem. Parasitol. 184(2) , 71-81, (2012)

Graphical abstract Toxoplasma gondii dihydroorotate dehydrogenase is an essential mitochondrial enzyme that exhibits inhibitor sensitivities distinct from those of the human and Plasmodium falciparum enzymes.

Site directed spin labeling studies of Escherichia coli dihydroorotate dehydrogenase N-terminal extension.

Biochem. Biophys. Res. Commun. 414(3) , 487-92, (2011)

Dihydroorotate dehydrogenases (DHODHs) are enzymes that catalyze the fourth step of the de novo synthesis of pyrimidine nucleotides. In this reaction, DHODH converts dihydroorotate to orotate, using a flavine mononucleotide as a cofactor. Since the synthesis ...

Thermodynamic basis of electron transfer in dihydroorotate dehydrogenase B from Lactococcus lactis: analysis by potentiometry, EPR spectroscopy, and ENDOR spectroscopy.

Biochemistry 43(21) , 6498-510, (2004)

Dihydroorotate dehydrogenase B (DHODB) is a complex iron-sulfur flavoprotein that catalyzes the conversion of dihydroorotate to orotate and the reduction of NAD(+). The enzyme is a dimer of heterodimers containing an FMN, an FAD, and a 2Fe-2S center. UV-visib...

Mutations in yhiT enable utilization of exogenous pyrimidine intermediates in Salmonella enterica serovar Typhimurium.

Microbiology 153(Pt 8) , 2472-82, (2007)

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 ...

Kinetic mechanism and catalysis of Trypanosoma cruzi dihydroorotate dehydrogenase enzyme evaluated by isothermal titration calorimetry.

Anal. Biochem. 399(1) , 13-22, (2010)

Trypanosoma cruzi dihydroorotate dehydrogenase (TcDHODH) catalyzes the oxidation of l-dihydroorotate to orotate with concomitant reduction of fumarate to succinate in the de novo pyrimidine biosynthetic pathway. Based on the important need to characterize cat...

Mechanism of the dihydroorotase reaction.

Biochemistry 43(51) , 16285-92, (2004)

Dihydroorotase (DHO) is a zinc metalloenzyme that functions in the pathway for the biosynthesis of pyrimidine nucleotides by catalyzing the reversible interconversion of carbamoyl aspartate and dihydroorotate. A chemical mechanism was proposed on the basis of...

Dihydroorotase from the hyperthermophile Aquifex aeolicus is activated by stoichiometric association with aspartate transcarbamoylase and forms a one-pot reactor for pyrimidine biosynthesis.

Biochemistry 48(4) , 766-78, (2009)

In prokaryotes, the first three enzymes in pyrimidine biosynthesis, carbamoyl phosphate synthetase (CPS), aspartate transcarbamoylase (ATC), and dihydroorotase (DHO), are commonly expressed separately and either function independently (Escherichia coli) or as...
