Description
Analysis Note Protein determined by biuret.
Biochem/physiol Actions Adenosine deaminase is a purine catabolic enzyme which catalyzes the deamination of adenosine and 2′-deoxyadenosine with approximay equal specificity. It is ubiquitous in mammalian tissue, and deficiency in adenosine deaminase has been associated with severe combined immunodeficiency disease. The enzyme has been tested as a target for gene therapy treatments of this disease.
