de·am·i·nas·es

(dē-am'i-nā-sĕz),
Enzymes catalyzing simple hydrolysis of C-NH2 bonds of purines, pyrimidines, and pterins, thus producing ammonia (usually named in terms of the substrate, for example, guanine deaminases, adenosine deaminases, AMP deaminases, pterin deaminases); not generally used for deamination of noncyclic amides. Deaminases are distinguished from ammonia-lyases in that the latter produce an unsaturation at the point of NH3 removal.
Synonym(s): deaminating enzymes
