13C Tracers for Glucose Degrading Pathway Discrimination in Gluconobacter oxydans 621H
Gluconobacter oxydans 621H is used as an industrial production organism due to its exceptional ability to incompletely oxidize a great variety of carbohydrates in the periplasm. With glucose as the carbon source, up to 90% of the initial concentration is oxidized periplasmatically to gluconate and ketogluconates. Growth on glucose is biphasic and intracellular sugar catabolism proceeds via the ...
متن کاملGluconobacter oxydans: its biotechnological applications.
Gluconobacter oxydans is a gram-negative bacterium belonging to the family Acetobacteraceae. G. oxydans is an obligate aerobe, having a respiratory type of metabolism using oxygen as the terminal electron acceptor. Gluconobacter strains flourish in sugary niches e.g. ripe grapes, apples, dates, garden soil, baker's soil, honeybees, fruit, cider, beer, wine. Gluconobacter strains are non-pathoge...
متن کاملIdentification of membrane-bound quinoprotein inositol dehydrogenase in Gluconobacter oxydans ATCC 621H.
The GOX1857 gene, which encodes a putative membrane-bound pyrroloquinoline quinone (PQQ)-dependent dehydrogenase in Gluconobacter oxydans ATCC 621H, was characterized. GOX1857 was disrupted and the oxidizing potential of the resulting mutant strain was compared to that of the wild-type. In contrast to the wild-type, the mutant was unable to grow with myo-inositol as the sole energy source and d...
متن کاملKnockout and overexpression of pyrroloquinoline quinone biosynthetic genes in Gluconobacter oxydans 621H.
In Gluconobacter oxydans, pyrroloquinoline quinone (PQQ) serves as the cofactor for various membrane-bound dehydrogenases that oxidize sugars and alcohols in the periplasm. Proteins for the biosynthesis of PQQ are encoded by the pqqABCDE gene cluster. Our reverse transcription-PCR and promoter analysis data indicated that the pqqA promoter represents the only promoter within the pqqABCDE cluste...
متن کاملCombined fluxomics and transcriptomics analysis of glucose catabolism via a partially cyclic pentose phosphate pathway in Gluconobacter oxydans 621H.
In this study, the distribution and regulation of periplasmic and cytoplasmic carbon fluxes in Gluconobacter oxydans 621H with glucose were studied by (13)C-based metabolic flux analysis ((13)C-MFA) in combination with transcriptomics and enzyme assays. For (13)C-MFA, cells were cultivated with specifically (13)C-labeled glucose, and intracellular metabolites were analyzed for their labeling pa...
