carbamoyl phosphate |
H2NCO-OPO32-;a reactive intermediate capable of transferring its carbamoyl group (H2NCO-) to an acceptor molecule, forming citrulline from ornithine in the urea cycle, and ureidosuccinic acid from aspartic acid in pyrimidine ring formation.
(05 Mar 2000) |
carbamoyl-phosphate synthase (ammonia) |
<enzyme> An enzyme that catalyses the formation of carbamoyl phosphate from ATP, carbon dioxide, and ammonia. This enzyme is specific for arginine biosynthesis or the urea cycle.
Chemical name: Carbon dioxide:ammonia ligase (ADP-forming, carbamate-phosphorylating)
Registry number: EC 6.3.4.16
(12 Dec 1998) |
carbamoyl-phosphate synthase (glutamine-hydrolyzing) |
<enzyme> An enzyme that catalyses the formation of carbamoyl phosphate from ATP, carbon dioxide, and glutamine. This enzyme is important in the de novo biosynthesis of pyrimidines.
Chemical name: Carbon dioxide:L-glutamine amido-ligase (ADP-forming, carbamate-phosphorylating)
Registry number: EC 6.3.5.5
(12 Dec 1998) |
carbamoyl phosphate synthetase |
A phosphotransferase catalyzing the formation of carbamoyl phosphate. There are two significant isozymes. Carbomoyl phosphate synthetase I is a mitochondrial enzyme that catalyses the reaction of 2ATP, NH3, CO2, and H2O to carbamoyl phosphate, 2ADP, and Pi. It is activated by N-acetylglutamate and participates in urea biosynthesis.
A deficiency of carbamoyl phosphate synthetase I can result in hyperammonaemia. Carbamoyl phosphate synthetase II is a cytosolic enzyme that, under physiological conditions, uses l-glutamine as the nitrogen source (producing l-glutamate) instead of NH3, is not activated by N-acetylglutamate, and is found in pyrimidine biosynthesis.
(05 Mar 2000) |
carbamyl phosphate |
<chemical> Phosphate salt of carbamic acid.
Chemical name: Carbamic acid, monoanhydride with phosphoric acid
(12 Dec 1998) |
galactose-1-phosphate |
A phosphorylated derivative of galactose that is key in galactose metabolism; accumulates in certain types of galactosaemia.
(05 Mar 2000) |
galactose-1-phosphate uridylyltransferase |
<enzyme> An enzyme catalyzing the reaction of UTP and alpha-d-galactose 1-phosphate to form UDPgalactose and pyrophosphate, the second and most important step in the metabolism of d-galactose; a deficiency of this enzyme results in an accumulation of galactose, galactose-1-phosphate, and galactitol.
