1. Deoxyadenosine metabolism was measured in freshly isolated mitochondria; these organelles took up the deoxynucleoside and formed three detectable products: deoxyinosine, dAMP and dIMP. 2. Enzyme extracts prepared from sonicated mitochondria exhibited deoxyadenosine deaminase, deoxyadenosine kinase, dAMP deaminase and deoxyinosine kinase activities. 3. These data suggest that deoxyadenosine was initially altered in mitochondria by at least two metabolic reactions--deamination and phosphorylation. Deoxyinosine and dAMP were produced. 4. These two products were subsequently phosphorylated and deaminated, respectively to produce dIMP.

A one-pot enzymatic synthesis of 2'-deoxyribonucleoside from glucose, acetaldehyde, and a nucleobase was established. Glycolysis by baker's yeast (Saccharomyces cerevisiae) generated ATP which was used to produce D: -glyceraldehyde 3-phosphate production from glucose via fructose 1,6-diphosphate. The D: -glyceraldehyde 3-phosphate produced was transformed to 2'-deoxyribonucleoside via 2-deoxyribose 5-phosphate and then 2-deoxyribose 1-phosphate in the presence of acetaldehyde and a nucleobase by deoxyriboaldolase, phosphopentomutase expressed in Escherichia coli, and a commercial nucleoside phosphorylase. About 33 mM 2'-deoxyinosine was produced from 600 mM glucose, 333 mM acetaldehyde and 100 mM adenine in 24 h. 2'-Deoxyinosine was produced from adenine due to the adenosine deaminase activity of E. coli transformants.
