In the pyrimidine biosynthetic pathway, N-carbamyl-L-aspartate (CA-asp) is converted to L-dihydroorotate (DHO) by dihydroorotase (DHOase). The mechanism of this important reaction was probed using primary and secondary 15N and 13C isotope effects on the ring opening of DHO using isotope

Dihydroorotate dehydrogenase (DHOD) from Trypanosoma cruzi (TcDHOD) is a member of family 1A DHOD that catalyzes the oxidation of dihydroorotate to orotate (first half-reaction) and then the reduction of fumarate to succinate (second half-reaction) in the de novo pyrimidine biosynthesis
Tamiko N Porter et al.
Biochemistry, 43(51), 16285-16292 (2004-12-22)
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 an analysis of the
Juliana Cheleski et al.

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 catalytic mechanism of TcDHODH, we have tailored
Idalia Sariego et al.
Parasitology international, 55(1), 11-16 (2005-09-21)
Dihydroorotate dehydrogenase (DHOD) is the fourth enzyme in the de novo pyrimidine biosynthetic pathway and is essential in Trypanosoma cruzi, the parasitic protist causing Chagas' disease. T. cruzi and human DHOD have different biochemical properties, including the electron acceptor capacities
