In enzymology, a CDP-ribitol ribitolphosphotransferase (EC 2.7.8.14) is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are CDP-ribitol and (ribitol phosphate)n, whereas its two products are CMP and (ribitol phosphate)n+1.
This enzyme belongs to the family of transferases, specifically those transferring non-standard substituted phosphate groups. The systematic name of this enzyme class is CDP-ribitol:poly(ribitol phosphate) ribitolphosphotransferase. Other names in common use include teichoic-acid synthase, polyribitol phosphate synthetase, teichoate synthetase, poly(ribitol phosphate) synthetase, polyribitol phosphate polymerase, and teichoate synthase.
Teichoic acids are bacterial copolymers of glycerol phosphate or ribitol phosphate and carbohydrates linked via phosphodiester bonds.
Carbamoyl phosphate synthetase catalyzes the ATP-dependent synthesis of carbamoyl phosphate from glutamine or ammonia and bicarbonate. This enzyme catalyzes the reaction of ATP and bicarbonate to produce carboxy phosphate and ADP. Carboxy phosphate reacts with ammonia to give carbamic acid. In turn, carbamic acid reacts with a second ATP to give carbamoyl phosphate plus ADP.
The enzyme indole-3-glycerol-phosphate synthase (IGPS) (EC 4.1.1.48) catalyzes the chemical reaction
