D-sorbitol-6-phosphate dehydrogenase from Lactobacillus casei.
Several different systems for the conversion of sorbitol to hexose have been described in microorganisms. In the pseudomonads, sorbitol may be oxidized to fructose (Shaw, 1956) or to sorbose (Sebek and Randles, 1952). The latter investigators concluded that the conversion of sorbitol to fructose or sorbose did not involve phosphorylation since carbon dioxide was not liberated from bicarbonate b...
متن کاملD-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...

متن کاملNucleotide Sequence of a cDNA Encoding NADP-Sorbitol-6-Phosphate Dehydrogenase from Apple.
Sorbitol plays a key role in the translocation of photosynthate in the Rosaceae family, including apple (Malus domestica), pear, and stone fruits (4, 7). NADP-S6PDH2 plays the most important role in biosynthesis of sorbitol in apple because its activity increases before accumulation of sorbitol in seedlings (8), and high activity is maintained in leaves (10). This enzyme reduces G6P to S6P usin...
متن کاملSorbitol dehydrogenase is a cytosolic protein required for sorbitol metabolism in Arabidopsis thaliana.
Sorbitol is converted to fructose in Rosaceae species by SORBITOL DEHYDROGENASE (SDH, EC 1.1.1.14), especially in sink organs. SDH has also been found in non-Rosaceae species and here we show that the protein encoded by At5g51970 in Arabidopsis thaliana (L.) Heynh. possesses the molecular characteristics of an SDH. Using a green fluorescent protein-tagged version and anti-SDH antisera, we deter...
