- What is the coenzyme of Phosphofructokinase-1?arrow_forwardPhosphoglycerate mutase (PGM) catalyzes the interconversion of 3-phosphoglycerate (3PG) and 2-phosphoglycerate (2PG) in the glycolytic and gluconeogenic pathways. a) To what enzyme class does PGM belong? b) There are two distinct classes of PGM, one which is dependent on 2,3-bisphosphoglycerate (2,3-BPG), dPGM, and one which is not, iPGM. dPGM uses acid base chemistry and a phosphorylated histidine residue to interconvert 3PG and 2PG. The dPGM reaction proceeds with formation of 2,3-BPG as an intermediate. Propose a mechanism for the dPGM-catalyzed conversion of 3PG to 2PG that is consistent with this information. c) What is the purpose of 2,3-BPG (i.e., why does dPGM require it)?arrow_forwardGlucose 6-phosphate can be converted into a molecule of glucose 1-phosphate, which can undergo additional modification to eventually be added to a polymer of glycogen. Glycogen is simply a long, branched polysaccharide comprised of glucose subunits. The four major reactions of the glycogen synthesis pathway are listed below. Glucose 6-phosphate → Glucose 1-phosphate Glucose 1-phosphate + UTP → UDP-glucose + PPi PPi + H2O → 2 Pi UDP-glucose + Glycogenn → Glycogenn+1 + UDP glycogenn - a polymer of glycogen composed of n subunits of glucose glycogenn+1 - a polymer of glycogen composed of n+1 subunits of glucose PPi - pyrophosphate, which is an ion composed of two phosphate groups UTP - uridine triphosphate, a nucleic acid like ATP; it has three phosphate groups UDP - uridine diphosphate, identical to UTP but with two phosphate groups instead of three What is the net reaction for the four reactions shown above?
