Application

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

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.

Electron paramagnetic resonance (EPR), electron-nuclear double resonance (ENDOR), and Mössbauer spectroscopies and other physical methods have provided important new insights into the radical-SAM superfamily of proteins, which use iron-sulfur clusters and S-adenosylmethionine to initiate H atom abstraction reactions. This remarkable

BtrN is a radical SAM ( S-adenosyl- l-methionine) enzyme that catalyzes the oxidation of 2-deoxy- scyllo-inosamine (DOIA) into 3-amino-2,3-dideoxy- scyllo-inosose (amino-DOI) during the biosynthesis of 2-deoxystreptamine (DOS) in the butirosin producer Bacillus circulans. Recently, we have shown that BtrN catalyzes

Adenosylmethionine-dependent radical enzymes provide a novel mechanism for generating the highly oxidizing 5'-deoxyadenosyl radical in an anaerobic reducing environment. Recent studies suggest a unique covalent interaction between adenosylmethionine and a catalytic iron-sulfur cluster that may promote inner-sphere electron transfer to
Gunhild Layer et al.

'Radical SAM' enzymes juxtapose a [4Fe-4S] cluster and S-adenosyl-l-methionine (SAM) to generate catalytic 5'-deoxyadenosyl radicals. The crystal structures of oxygen-independent coproporphyrinogen III oxidase HemN and biotin synthase reveal the positioning of both cofactors with respect to each other and relative
