Adenosine Deaminase/ADA: Proteins and Enzymes

Adenosine deaminase is an enzyme involved in purine metabolism. It is needed for the breakdown of adenosine from food and from the turnover of nucleic acids in tissues. It irreversibly deaminates adenosine, converting it to the related nucleoside inosine by the removal of an amine group. Inosine can then be deribosylated (removed from ribose) by another enzyme called purine nucleoside phosphorylase (PNP), converting it to hypoxanthine. Mutations in the gene for adenosine deaminase causing it ...
