In enzymology a ribose-5-phosphate-ammonia ligase (EC 6.3.4.7) is an enzyme that catalyzes the chemical reactionATP + ribose 5-phosphate + NH3 ADP + phosphate + 5-phosphoribosylamineThe 3 substrates of this enzyme are ATP ribose 5-phosphate and NH3 whereas its 3 products are ADP phosphate and 5-phosphoribosylamine.This enzyme belongs to the family of ligases specifically those forming generic carbon-nitrogen bonds.
