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 ...
متن کاملD-Mannitol 1-phosphate dehydrogenase from Escherichia coli.
D-Mannitol is the most widely distributed of the naturally occurring hexahydric alcohols, and the compound has been known since the early part of the nineteenth century. It is found as a reserve material in some algae and many higher plan&. In some lower fungi it is the product of the fermentation of sugars. Finally, mannitol is utilized for growth and fermented by a large number of species of ...
متن کاملEnd Products of Glucose Fermentation by Brochothrix thermosphacta.
Anaerobically, Brochothrix thermosphacta fermented glucose primarily to l-lactate, acetate, formate, and ethanol. The ratio of these end products varied with growth conditions. Both the presence of acetate and formate and a pH below about 6 increased l-lactate production from glucose. Small amounts of butane-2,3-diol were also produced when the pH of the culture was low (</=5.5) or when acetate...
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 کاملانتقال ژن رمز کننده mannitol-1-phosphate dehydrogenase به چغندرقند بواسطه agrobacterium tumefaciens
تنش های غیرزیستی، به ویژه شوری و خشکی علل اصلی کاهش محصول در جهان می باشند. این تنش ها شدیداً بر عملکرد چغندرقند و کیفیت آن تأثیر می گذارند. ثابت شده است که مانیتول نقش محوری در تعدیل تنش های اسمزی و شوری در گیاهان دارد. ژن mtld آنزیم مانیتول-1- فسفات دهیدروژناز را رمز می کند که این آنزیم بیوسنتز مانیتول را کاتالیز می نماید. در این تحقیق از دو ژنوتیپ دیپلویید چغندرقند sbs1-4 و sbs1-5 برای تراریخ...
