Glycolytic enzymes in Zymomonas mobilis.
Raps, Shirley (University of Illinois, Urbana) and R. D. DeMoss. Glycolytic enzymes in Zymomonas mobilis. J. Bacteriol. 84:115-118. 1962-An enzyme extract of Zymomonas mobilis (Pseudomonas lindneri) was capable of fermenting glucose-6-phosphate to CO(2) and ethanol. The extract was found to contain phosphohexoisomerase, aldolase, and glyceraldehyde-3-phosphate dehydrogenase, but no demonstrable...
متن کاملProduction of Acetaldehyde by Zymomonas mobilis.
Mutants of Zymomonas mobilis were selected for decreased alcohol dehydrogenase activity by using consecutively higher concentrations of allyl alcohol. A mutant selected by using 100 mM allyl alcohol produced acetaldehyde at a level of 4.08 g/liter when the organism was grown in aerated batch cultures on a medium containing 4.0% (wt/wt) glucose. On the basis of the amount of glucose utilized, th...
متن کاملPyruvate decarboxylase from Zymomonas mobilis
To study the mechanism of re-activation of Zymomonas mobilis pyruvate decarboxylase apoenzyme by its cofactors thiamin diphosphate and Mg2", cofactor-free enzyme was prepared by dialysis against I mM-dipicolinic acid at pH 8.2. This apoenzyme was then used in a series of experiments that included determination of: (a) the affinity towards one cofactor when the other was present at saturating co...
متن کاملIsolation and properties of the glycolytic enzymes from Zymomonas mobilis. The five enzymes from glyceraldehyde-3-phosphate dehydrogenase through to pyruvate kinase.
The five glycolytic enzymes glyceraldehyde-3-phosphate dehydrogenase, phosphoglycerate kinase, phosphoglycerate mutase, enolase and pyruvate kinase were each purified from extracts of Zymomonas mobilis cells, by using dye-ligand chromatography as the principal step. Two procedures, producing three and two of the enzymes respectively, are described in detail. Z. mobilis glyceraldehyde-phosphate ...
متن کاملDifferential Expression of Zymomonas mobilis Sucrase Genes (sacB and sacC) in Escherichia coli and Sucrase Mutants of Zymomonas mobilis
The sacB and sacC genes encoding levansucrase and extracellular sucrase respectively were independently subcloned in pBluescript (high copy number) and in Z. mobilis-E. coli shuttle vector, pZA22 (low copy number). The expression of these genes were compared under identical background of E. coli and Z. mobilis host. The level of sacB gene expression in E. coli was almost ten fold less than the ...
