Description
5'-Deoxyadenosine is an oxidized nucleoside found in the urine of normal subjects. Oxidized nucleosides represent excellent biomarkers for determining the extent of damage in genetic material, which has long been of interest in understanding the mechanism of aging, neurodegenerative diseases, and carcinogenesis.
Uses
5′-Deoxyadenosine has been used:
- as a standard in mass spectroscopy
- as an inhibitor for screening thymidine phosphorylase activity
- as a substrate in 5′-Deoxyadenosine deaminase (DadD) assay
Definition
ChEBI: A 5'-deoxyribonucleoside compound having adenosine as the nucleobase.
Biochem/physiol Actions
5′-Deoxyadenosine is a substrate for the enzyme methylthioadenosine/S-adenosylhomocysteine (MTA/SAH) nucleosidase in microbes. 5′-Deoxyadenosine is a byproduct of cleavage of S-adenosylmethionine (SAM). High levels of 5′-Deoxyadenosine inhibits SAM dependent enzymes. It also inhibits biotin synthase (BioB) and lipoyl synthase (LipA) enzymes.
