>TIGR01251 ribP_PPkin ribose-phosphate pyrophosphokinase; InterPro: IPR005946 Synonyms: phosphoribosylpyrophosphate synthetase Phosphoribosyldiphosphate synthetase (PRPPsase, 2.7.6.1 from EC) catalyzes the transfer of an intact diphosphate (PP) group from ATP to ribose-5-phosphate (R-5-P), which results in the formation of AMP and 5-phospho-D-ribosyl--1-diphosphate (PRPP). ATP + D-ribose 5-phosphate = AMP + 5-phospho-alpha-D-ribose 1-diphosphate PRPP is an essential precursor for purine and pyrimidine nucleotides, both in the de novo synthesis and in the salvage pathway as well as in the synthesis of pyridine nucleotide coenzymes. The activity of PRPPsase is highly regulated. Besides competitive inhibition at the substrate binding sites, most PRPPsases are regulated in an allosteric manner, in which ADP generally acts as the most potent inhibitor. In some systems, close homologs lacking enzymatic activity exist and perform regulatory functions.; GO: 0000287 magnesium ion binding, 0004749 ribose phosphate diphosphokinase activity, 0009165 nucleotide biosynthetic process.
