Ribose and arabinose
Webb9 feb. 2024 · l-Ribose, a starting material for the synthesis of l-nucleoside, has attracted lots of attention since l-nucleoside is responsible for the antiviral activities of the racemic mixtures of nucleoside enantiomers. In this study, the l-ribulose-producing Candida tropicalis strain was engineered for the conversion of l-arabinose to l-ribose. Webbl-Ribose and l-arabinose were prepared biochemically from ribitol via a two-step reaction, by which the complete oxidation of ribitol to l-ribulose (∼98%) was achieved by the reaction of washed cells of Acetobacter …
