'''ATP Phosphoribosyl transferase''' (ATP-PRTase) (EC 2.4.2.17), also called '''HisG''', belongs to the enzyme super family, phosphoribosyl transferases (PRTases) and the glycosyltransferases family. It catalyzes the reversible condensation of 5-phosphoribosyl-α-1-pyrophosphate (PRPP) with ATP, yielding N’-5’-phosphoribosyl-ATP (PR-ATP) and inorganic pyrophosphate (PPi). | '''ATP Phosphoribosyl transferase''' (ATP-PRTase) (EC 2.4.2.17), also called '''HisG''', belongs to the enzyme super family, phosphoribosyl transferases (PRTases) and the glycosyltransferases family.
