Allosteric control of Zymomonas mobilis glucose-6-phosphate dehydrogenase by phosphoenolpyruvate.
The second enzyme of the Entner-Doudoroff glycolytic pathway in Zymomonas mobilis, glucose-6-phosphate dehydrogenase, has been found to be inhibited by phosphoenolpyruvate (PEP). In the presence of PEP levels in the micromolar range, the response of the enzyme to glucose 6-phosphate concentration becomes sigmoidal, with a Hill coefficient up to 2. At low ionic strength in the absence of PEP, th...
متن کاملFinished Genome of Zymomonas mobilis subsp. mobilis Strain CP4, an Applied Ethanol Producer
Zymomonas mobilis subsp. mobilis is one of the most rigorous ethanol-producing organisms known to date, considered by many to be the prokaryotic alternative to yeast. The two most applied Z. mobilis subsp. mobilis strains, ZM4 and CP4, derive from Recife, Brazil, and have been isolated from sugarcane fermentations. Of these, ZM4 was the first Z. mobilis representative strain to be sequenced and...
متن کاملGlucose-6-Phosphate Dehydrogenase
Description Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency is the most common human enzyme deficiency that mainly affects the red blood cells (RBCs). A defect in G6PD enzyme leads to the destruction of premature RBCs causing hemolytic anemia because the body can not compensate the destroyed RBCs. Thus, the affected individuals show jaundice (paleness, yellowing of the skin and whites of th...
متن کاملThe regulation of glucose-6-phosphate dehydrogenase in chloroplasts.
Glucose-6-phosphate dehydrogenase from intact pea chloroplasts is partially membrane bound and inactivated upon illumination. The inhibitory effect of light can be abolished by addition of methylviologen. Kinetic experiments with glucose-6-phosphate dehydrogenase reveal that, in the dark, the enzyme activity is strongly inhibited by the accumulation of NADPH. The inhibition of NADPH can be reve...
متن کاملRegulation of glucose-6-phosphate dehydrogenase in human erythrocytes.
Glucose-6-phosphate dehydrogenase catalyzes the initial and committed step of the pathway that is the principal source of NADPH in many cells. The intracellular rate of the enzyme in human erythrocytes was estimated from the rate at which the cells generated 14CO2 from 14C-labeled glucose in the presence of different amounts of methylene blue. This investigation differed from earlier studies in...
