ABSTRACT
2-Deoxyribose 5-phosphate was produced from acetaldehyde and dihydroxyacetone phosphate via D-glyceraldehyde 3-phosphate by Klebsiella pneumoniae B-4-4 through deoxyriboaldolase- and triosephosphate isomerase-catalyzing reactions. Under the optimum conditions, 98.7 mM 2-deoxyribose 5-phosphate was produced from 200 mM acetaldehyde and 117 mM dihydroxyacetone phosphate in 2 h with a molar yield of 84%. The 2-deoxyriobse 5-phosphate produced was directly transformed to 2'-deoxyribonucleoside by phosphopentomutase- and nucleoside phosphorylase-catalyzing reactions.
