| Application: | Adenosine Deaminase (ADA) has been used as a component of macrophage- serum-free media (SFM) to treat macrophages. |
| Application: | Adenosine deaminase has been used to pre-treat primary Kupffer cells. |
| Biochem/physiol Actions: | Adenosine Deaminase (ADA) catalyzes the deamination of adenosine analogs to the corresponding inosine analogs. It is present in high levels in colorectal cancer and is a potential marker in tuberculous pleuriti. ADA deficiency affects T-and B-lymphocytes resulting in severe combined immunodeficiency (SCID) leading to lymphocytopenia. |
| Biochem/physiol Actions: | Adenosine deaminase (ADA) is involved in the deamination of adenosine to inosine and 2′ deoxyadenosine to 2′-deoxyinosine. |
| General description: | Adenosine deaminase (ADA) is a zinc metalloenzyme. |
| General description: | Adenosine Deaminase (ADA) is present majorly in the proximal small intestine and the duodenum. It is also called Adenosine aminohydrolase. It is a zinc metalloenzyme and exists as a high (230−440 kDa) and low molecular weight (30−47 kDa) isoforms. |
