...Glucose-6-phosphate isomerase, or phosphoglucose isomerase, is an enzyme () that catalyzes the conversion of glucose-6-phosphate into fructose 6-phosphate in the second step of glycolysis. It should not be confused with "glucose isomerase", which is actually a common name for D-xylose isomerase () in the high-fructose corn syrup industry. Read full entry

what are the advantages of i need an answer desperately

You can put a stream of glucose or fructose past the immobilized enzyme, and have a continuous output of isomerized material. You will not have to purify the enzyme out of the product. |

Cofactors/Coenzymes for Anyone by chance know the
cofactors/coenzymes for
glucose-6-phosphate isomerase?
This is for a biology research
thing in highschool, I can't
find it on the internet no
matter what resources I use
and/or what ways i use to
search.
Any would be greatly
appreciated!

The second step of GLYCOLYSIS is the conversion of Glucose 6-Phosphate (G6P) to Fructose-6-Phosphate by the enzyme Glucose-6-phosphate Isomerase, also known as Phosphoglucose Isomerase. Coenzymes for the converstion of G6P to Fructose-6-Phosphate are Phosphoglucose Isomerase and Acetyl-Coenzyme A, and cofactors include NADP+ (nicotine adenosine diphosphate), an electron acceptor of the electron transport chain, and ADP (adenosine diphosphate), which stores energy via acceptance of a phosphate group. |

Triose Phosphate Isomerase is a glycolytic enzyme that converts Dehydroxy Acetone Phosphate (DHAP) to Glyceraldehyde-3-Phosphate (G3P), which will then enter the payoff phase of glycolysis. Fructose-1,6-bisphosphate is also converted to G3P by the enzyme Aldolase. The two molecules of G3P are thus what give the yield of 4 ATP molecules, 2 ATP per G3P. A defect in the Triose Phosphate Isomerase enzyme would mean that 2 ATP molecules would be lost and the payoff phase (which should then no more be called as such). In the preparatory phase of Glycolysis, 2 ATP are invested and this would mean, overall there is no net ATP yield. For organisms that use Glycolysis solely for metabolism, a defect in the enzyme thus means death since there is no ATP being produced. |
