Guanosine deaminase

From Wikipedia, the free encyclopedia

In enzymology, a guanosine deaminase (EC 3.5.4.15) is an enzyme that catalyzes the chemical reaction

guanosine + H₂O xanthosine + NH₃

Thus, 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.
