Abstract

The -inositol catabolism pathway of has not been fully characterized but was proposed to involve step-wise multiple reactions that finally yielded acetyl-CoA and dihydroxyacetone phosphate. It is known that the operon is responsible for the catabolism of inositol. IolG catalyses the first step of -inositol catabolism, the dehydrogenation of -inositol, producing 2-keto--inositol (inosose). The second step was thought to be the dehydration of inosose. Genetic and biochemical analyses of the genes led to the identification of , encoding the enzyme for the second step of inositol catabolism, inosose dehydratase. The reaction product of inosose dehydratase was identified as -2,3-diketo-4-deoxy--inositol.
