In enzymology, a ribose-5-phosphate—ammonia ligase (EC 6.3.4.7) is an enzyme that catalyzes the chemical reaction
- ATP + ribose 5-phosphate + NH3 ADP + phosphate + 5-phosphoribosylamine
The 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. The systematic name of this enzyme class is ribose-5-phosphate:ammonia ligase (ADP-forming). This enzyme participates in purine metabolism.
