deaminases

Type: Term

Pronunciation: dē-am′i-nā-sĕz

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
