adenosine deaminase

adenosine deaminase
adenosine deaminase n an enzyme which catalyzes the conversion of adenosine to inosine and whose deficiency causes a form of severe combined immunodeficiency disease as a result of the accumulation of toxic metabolites which inhibit DNA synthesis abbr. ADA

(ADA) aden·o·sine de·am·i·nase (ADA) (ə-denґo-sēn de-amґĭ-nās) [EC 3.5.4.4] an enzyme of the hydrolase class that catalyzes the deamination of adenosine to form inosine, a reaction of purine metabolism. Absence of enzyme activity, an autosomal recessive trait, has been found in many individuals with severe combined immunodeficiency disease.
