RESUMO
Mutations affecting the genes involved in B. subtilis D-glucitol catabolism were mapped either by PBS1-mediated transduction or DNA-mediated transformation. It was shown that the genes gutA and gutB coding for the D-glucitol permease and the D-glucitol dehydrogenase, respectively, and regulatory locus gutR are clustered in a gut operon localized between purB and dal close to the pha marker. A mutation affecting fructokinase activity (fruC) was mapped near the gut markers. The fruC gene does not belong to the operon. A mutation affecting phosphofructokinase activity (pfk) was mapped between the leuA and aroG markers.
