Dihydroororate reductase in humans catalyses a key step in the synthesis of pyrimidines, as it is able to convert dihydroororate into ororate, using FMN and Ubiquinone as cofactors for the reaction. The human enzyme is part of family 2, with homology to other mammalian dihydroororate reductases and to the equivalent enzymes in bacteria which are clustered in family 1. The enzyme is particularly important in T cells because of their high nucleotide turnover through new DNA synthesis.
