HHsearch alignment for GI: 254781012 and conserved domain: TIGR00857
>TIGR00857 pyrC_multi dihydroorotase, multifunctional complex type; InterPro: IPR004722 Dihydroorotase belongs to MEROPS peptidase family M38 (clan MJ), where it is classified as a non-peptidase homologue. DHOase catalyses the third step in the de novo biosynthesis of pyrimidine, the conversion of ureidosuccinic acid (N-carbamoyl-L-aspartate) into dihydroorotate. Dihydroorotase binds a zinc ion which is required for its catalytic activity . In bacteria, DHOase is a dimer of identical chains of about 400 amino-acid residues (gene pyrC). In higher eukaryotes, DHOase is part of a large multi-functional protein known as 'rudimentary' in Drosophila melanogaster and CAD in mammals and which catalyzes the first three steps of pyrimidine biosynthesis . The DHOase domain is located in the central part of this polyprotein. In yeasts, DHOase is encoded by a monofunctional protein (gene URA4). However, a defective DHOase domain is found in a multifunctional protein (gene URA2) that catalyzes the first two steps of pyrimidine biosynthesis. The comparison of DHOase sequences from various sources shows that there are two highly conserved regions. The first located in the N-terminal extremity contains two histidine residues suggested to be involved in binding the zinc ion. The second is found in the C-terminal part. Members of this family of proteins are predicted to adopt a TIM barrel fold . Dihydroorotase 'multifunctional complex type' 3.5.2.3 from EC, in contrast to the homodimeric type of dihydroorotase found in Escherichia coli, tends to appear in a large multifunctional complex with aspartate transcarbamoylase. Homologous domains appear in multifunctional proteins of higher eukaryotes. In some species, including Pseudomonas putida and Pseudomonas aeruginosa, this protein is inactive but is required as a non-catalytic subunit of aspartate transcarbamoylase (ATCase). In these species, a second, active dihydroorotase is also present..
