Mannitol-1-phosphate dehydrogenase (MtlD) is required for mannitol and glucitol assimilation in Bacillus subtilis: possible cooperation of mtl and gut operons.

We found that mannitol-1-phosphate dehydrogenase (MtlD), a component of the mannitol-specific phosphotransferase system, is required for glucitol assimilation in addition to GutR, GutB, and GutP in Bacillus subtilis. Northern hybridization of total RNA and microarray studies of RNA from cells cultured on glucose, mannitol, and glucitol indicated that mannitol as the sole carbon source induced h...

Spatial and developmental differentiation of mannitol dehydrogenase and mannitol-1-phosphate dehydrogenase in Aspergillus niger.

The presence of a mannitol cycle in fungi has been subject to discussion for many years. Recent studies have found no evidence for the presence of this cycle and its putative role in regenerating NADPH. However, all enzymes of the cycle could be measured in cultures of Aspergillus niger. In this study we have analyzed the localization of two enzymes from the pathway, mannitol dehydrogenase and ...

Catabolism of fructose and mannitol in Clostridium thermocellum: presence of phosphoenolpyruvate: fructose phosphotransferase, fructose 1-phosphate kinase, phosphoenolpyruvate: mannitol phosphotransferase, and mannitol 1-phosphate dehydrogenase in cell extracts.

Fructose and mannitol are fermented by Clostridium thermocellum in a medium containing salts and 0.5% yeast extract. The initial reaction in the catabolism of fructose was found to be the formation of fructose l-phosphate by phosphoenolpyruvate (PEP):fructose phosphotransferase which resembles the Kundig-Roseman phosphotransferase system. The phosphorylation of fructose l-phosphate to form fruc...

D-Mannitol 1-phosphate dehydrogenase and D-sorbitol 6-phosphate dehydrogenase in Aerobacter aerogenes.

n-Mannitol has been used as a carbon source for the growth of many microorganisms. Some bacteria contain diphosphopyridine nucleotide-dependent dehydrogenases that will oxidize n-mannitol to n-fructose at the nonphosphorylated level (2-5). On the other hand, Wolff and Kaplan (6, 7) have reported the presence of a diphosphopyridine nucleotide-dependent n-mannitol l-phosphate dehydrogenase that o...

Possible roles for mannitol and mannitol dehydrogenase in the biotrophic plant pathogen Uromyces fabae.

Levels of the C6-polyol mannitol were observed to rise dramatically in the biotrophic interaction of the rust fungus Uromyces fabae and its host plant Vicia faba. Mannitol was found in millimolar concentrations in extracts and apoplastic fluids of infected leaves and also in extracts of spores. We suggest that this polyol might have at least a dual function: first, as a carbohydrate storage com...
