| phosphoribosylglycineamide synthetase | Glycinamide ribonucleotide synthetase;an enzyme that reacts glycine with ribosylamine 5-phosphate and ATP to form ADP, orthophosphate, and phosphoribosylglycineamide in the course of purine biosynthesis. (05 Mar 2000) |
| phosphoribosyltransferase | One of a group of enzymes (EC sub-subclass 2.4.2, pentosyltransferases) that transfers d-ribose 5-phosphate from 5-phospho-alpha-d-ribosyl pyrophosphate to a purine, pyrimidine, or pyridine acceptor, forming a 5'-nucleotide and inorganic pyrophosphate, or d-ribose from d-ribosyl phosphate to a base, forming a nucleoside, or similar pentose transfers; important in nucleotide biosynthesis.
