The salvage of adenine begins with adenine being transporter into the cytosol through a adeP hydrogen symporter. Once in the cytosol adenine is degraded by reacting with a ribose-1-phosphate through an adenosine phosphorylase resulting in the release of a phosphate and adenosine. Adenosine is then deaminated by reacting with water, a hydrogen ion and an adenosine deaminase resulting in the release of an ammonium and a inosine . Inosine can then be phosphorylated through an ATP driven inosine kinase resulting in the release of an ADP, a hydrogen ion and a IMP
