In enzymology, a guanosine deaminase (EC 3.5.4.15) is an enzyme that catalyzes the chemical reaction
- guanosine + H2O xanthosine + NH3
xanthosine + NH3Thus, the two substrates of this enzyme are guanosine and H2O, whereas its two products are xanthosine and NH3.
This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in cyclic amidines. The systematic name of this enzyme class is guanosine aminohydrolase. This enzyme is also called guanosine aminase.
