ATP phosphoribosyltransferase

UniProtKB accession:  Q9X0D2

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the condensation of ATP and 5-phosphoribose 1-diphosphate to form N'-(5'-phosphoribosyl)-ATP (PR-ATP). Has a crucial role in the pathway because the rate of histidine biosynthesis seems to be controlled primarily by regulation of HisG enzymatic activity (By similarity).
