Supplementary information

Adenosine deaminase (ADA) sometimes known as deaminase is an enzyme that plays a critical mechanical role in cellular metabolism. This enzyme catalyzes the deamination of adenosine converting it into inosine. ADA is a 41 kDa protein primarily expressed in most tissues including the thymus and spleen. Various ADA assays and ADA protocols exist to study its functionality and quantification often using ADA ELISA kits to measure ADA activity in biological samples. In cell lines such as HeLa ADA expression is also present and significant for studying its regulation and function.
Biological function summary

Adenosine deaminase activity influences purine metabolism playing an important role in the breakdown of adenosine. It is not part of a complex but interacts closely with other components of the purine salvage pathway to maintain nucleotide balance. This enzyme is important for the proper function of immune cells as it prevents toxic accumulations of adenosine which can be detrimental to lymphocyte proliferation and function. ADA's activity ensures the proper management of nucleotides within cells sustaining cellular health and functionality.

Pathways

Adenosine deaminase plays significant roles in the immune and purine catabolism pathways. Within these pathways ADA is closely related to proteins such as purine nucleoside phosphorylase (PNP) which together orchestrate the steps necessary for adenine and guanine nucleotide turnover. These proteins facilitate the conversion processes needed for cellular nucleic acid synthesis and energy regulation. By managing adenosine levels ADA's function ensures the smooth operation of cellular signaling and metabolic balance.

Adenosine deaminase deficiency is linked to severe combined immunodeficiency (SCID) and can also be associated with pulmonary disorders like asthma. A lack of ADA activity leads to the accumulation of toxic metabolites impairing immune function and contributing to the pathogenesis of SCID. In some patients with pulmonary disorders altered ADA activity impacts the inflammatory response. ADA's mechanistic interactions with other proteins such as PNP highlight its importance in maintaining immune competence and metabolic homeostasis emphasizing the enzyme's role in these clinical conditions.

General info

Function

Catalyzes the hydrolytic deamination of adenosine and 2-deoxyadenosine (PubMed : 16670267, PubMed : 23193172, PubMed : 26166670, PubMed : 8452534, PubMed : 9361033). Plays an important role in purine metabolism and in adenosine homeostasis. Modulates signaling by extracellular adenosine, and so contributes indirectly to cellular signaling events. Acts as a positive regulator of T-cell coactivation, by binding DPP4 (PubMed : 20959412). Its interaction with DPP4 regulates lymphocyte-epithelial cell adhesion (PubMed : 11772392). Enhances dendritic cell immunogenicity by affecting dendritic cell costimulatory molecule expression and cytokines and chemokines secretion (By similarity). Enhances CD4+ T-cell differentiation and proliferation (PubMed : 20959412). Acts as a positive modulator of adenosine receptors ADORA1 and ADORA2A, by enhancing their ligand affinity via conformational change (PubMed : 23193172). Stimulates plasminogen activation (PubMed : 15016824). Plays a role in male fertility (PubMed : 21919946, PubMed : 26166670). Plays a protective role in early postimplantation embryonic development (By similarity). Also responsible for the deamination of cordycepin (3'-deoxyadenosine), a fungal natural product that shows antitumor, antibacterial, antifungal, antivirus, and immune regulation properties (PubMed : 26038697).
