WebMay 15, 2008 · It has been postulated that carboxyphosphate (1) ( Fig. 1) is an “activated carbon dioxide” intermediate in biotin-dependent carboxylations [1], [2], [3], [4], [5]. The presence of carboxyphosphate was confirmed by Powers and Meister [6], [7] in reactions of glutamine-dependent carbamoyl phosphate synthetase. WebJan 1, 2015 · Carboxyphosphate (CP) is an important intermediate involved in reactions catalyzed by acetyl-CoA carboxylase, pyruvate carboxylase, N5-Carboxyaminoimidazole ribonucleotide synthetase, propionyl-CoA carboxylase, urea amidolyase, and carbamoyl phosphate synthetase.
