Haloferax volcanii degrades the pentoses D-xylose and L-arabinose via an oxidative pathway to α-ketoglutarate as an intermediate. The initial dehydrogenases of the pathway, D-xylose dehydrogenase (XDH) and L-arabinose dehydrogenase (L-AraDH) catalyze the NADP+ dependent D-xylose and L-arabinose oxidation. It is

Free radical attack on the sugar-phosphate backbone generates oxidized apurinic/apyrimidinic (AP) residues in DNA. 2'-deoxyribonolactone (dL) is a C1'-oxidized AP site damage generated by UV and gamma-irradiation, and certain anticancer drugs. If not repaired dL produces G-->A transitions in Escherichia
