Protein Family Models

Phosphoribosylglycinamide synthetase catalyses the second step in the de novo biosynthesis of purine. The reaction catalysed by Phosphoribosylglycinamide synthetase is the ATP- dependent addition of 5-phosphoribosylamine to glycine to form 5'phosphoribosylglycinamide. This domain is related to the N-terminal domain of biotin carboxylase/carbamoyl phosphate synthetase (see Pfam:PF00289). This domain is structurally related to the PreATP-grasp domain. [1]. 2687276.

The reaction catalysed by Phosphoribosylglycinamide synthetase is the ATP- dependent addition of 5-phosphoribosylamine to glycine to form 5'phosphoribosylglycinamide. This domain is related to the C-terminal domain of biotin carboxylase/carbamoyl phosphate synthetase (see Pfam:PF02787). [1]. 2687276.

Carbamoyl-phosphate synthase catalyses the ATP-dependent synthesis of carbamyl-phosphate from glutamine or ammonia and bicarbonate. This important enzyme initiates both the urea cycle and the biosynthesis of arginine and/or pyrimidines [2]. The carbamoyl-phosphate synthase (CPS) enzyme in prokaryotes is a heterodimer of a small and large chain. The small chain promotes the hydrolysis of glutamine to ammonia, which is used by the large chain to synthesise carbamoyl phosphate. See Pfam:PF00988. The small chain has a GATase domain in the carboxyl terminus. See Pfam:PF00117. The ATP binding domain (this one) has an ATP-grasp fold. [1]. 7915138.

phosphoribosylamine--glycine ligase catalyzes the second step of the de novo purine biosynthetic pathway; the conversion of phosphoribosylamine, glycine, and ATP to glycinamide ribonucleotide (GAR), ADP, and Pi

Phosphoribosylamine--glycine ligase catalyzes the formation of N(1)-(5-phospho-D-ribosyl)glycinamide from 5-phospho-D-ribosylamine and glycine in purine biosynthesis. It is also called glycinamide ribonucleotide synthetase (GARS). This enzyme appears as a monofunctional protein in prokaryotes but as part of a larger, multidomain protein in eukaryotes.
