| General description【一般描述】 | Mannitol dehydrogenase (MDH) is a NAD-dependent enzyme, obtained from several organisms like, Lactobacillus brevis, Leuconostoc mesenteroides, Absidia glauca and Rhodococcus. MDH obtained from L. mesenteroides exhibits similarity in sequence with the medium-chain dehydrogenase/reductase protein family. It also contains four identical subunits of about 38 kDa in size. The molecular weight of mannitol dehydrogenase is 136 kDa. Mannitol dehydrogenase is a cytoplasmic enzyme whose primary role is the regulation of intracellular levels of the sugar alcohol mannitol in plants. It catalyzes the pyridine nucleotide dependent reduction of fructose to mannitol. |
| Application【应用】 | It has been used in a study to assess glucosylglycerol and glucosylglycerate as enzyme stabilizers. Can be used for the production of D-mannitol. This preparation is useful in the determination of mannitol in urine. |
