Title Isolation and properties of a Bacillus subtilis mutant unable to produce fructose-bisphosphatase.
Journal J Bacteriol
Abstract A Bacillus subtilis mutation (gene symbol fdpA1), producing a deficiency of D-fructose-1,6-bisphosphate 1-phosphohydrolase (EC, fructose-bisphosphatase), was isolated and genetically purified. An fdpA1-containing mutant did not produce cross-reacting material. It grew on any carbon source that allowed growth of the standard strain except myo-inositol and D-gluconate. Because the mutant could grow on D-fructose, glycerol, or L-malate as the sole carbon source, B. subtilis can produce fructose-6-phosphate and the derived cell wall precursors from these carbon sources in the absence of fructose-bisphosphatase. In other words, during gluconeogenesis B. subtilis must be able to bypass this reaction. Fructose-bisphosphatase is also not needed for the sporulation of B., subtilis. The fdpA1 mutation has the pleiotropic consequence that mutants carrying it cannot produce inositol dehydrogenase (EC and gluconate kinase (EC under conditions that normally induce these enzymes.
