Deaminases[dē-am′i-nā-sĕz]

Type:Term

Definitions
1. Enzymes catalyzing simple hydrolysis of C—NH2 bonds of purines, pyrimidines, and pterins, thus producing ammonia (usually named in terms of the substrate, 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.

Synonyms
deaminating enzymes
