The influence of fructose-1:6-bisphosphate on the release of glycolytic enzymes from cellular structure. 1986

C Nanhua, and D Nancarrow, and C Masters

In order to provide information on the relative binding characteristics of glycolytic enzymes, the effect of fructose-1,6-bisphosphate (FBP) on the release of glycolytic enzymes from cultured pig kidney cells treated with digitonin has been studied. In the absence of FBP, a differential release of these enzymes was observed, with the order of retention being aldolase greater than glyceraldehyde-3-phosphate dehydrogenase greater than glucosephosphate isomerase, triosephosphate isomerase, phosphoglycerokinase, phosphoglucomutase, lactate dehydrogenase, enolase, pyruvate kinase and phosphofructokinase. In the presence of fructose-1,6-bisphosphate, the release of aldolase was considerably enhanced, whereas the release of phosphofructokinase and pyruvate kinase was decreased by this metabolite. No significant alterations in the rate of release of the other enzymes was caused by FBP. These data have been discussed in relation to their contribution to the knowledge of the degree of association and order of binding between glycolytic enzymes and the cytoplasmic matrix.

UI	MeSH Term	Description	Entries
D007668	Kidney	Body organ that filters blood for the secretion of URINE and that regulates ion concentrations.	Kidneys
D007700	Kinetics	The rate dynamics in chemical or physical systems.
D002460	Cell Line	Established cell cultures that have the potential to propagate indefinitely.	Cell Lines,Line, Cell,Lines, Cell
D004072	Digitonin	A glycoside obtained from Digitalis purpurea; the aglycone is digitogenin which is bound to five sugars. Digitonin solubilizes lipids, especially in membranes and is used as a tool in cellular biochemistry, and reagent for precipitating cholesterol. It has no cardiac effects.	Digitin
D005635	Fructosediphosphates	Diphosphoric acid esters of fructose. The fructose-1,6- diphosphate isomer is most prevalent. It is an important intermediate in the glycolysis process.
D006019	Glycolysis	A metabolic process that converts GLUCOSE into two molecules of PYRUVIC ACID through a series of enzymatic reactions. Energy generated by this process is conserved in two molecules of ATP. Glycolysis is the universal catabolic pathway for glucose, free glucose, or glucose derived from complex CARBOHYDRATES, such as GLYCOGEN and STARCH.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013552	Swine	Any of various animals that constitute the family Suidae and comprise stout-bodied, short-legged omnivorous mammals with thick skin, usually covered with coarse bristles, a rather long mobile snout, and small tail. Included are the genera Babyrousa, Phacochoerus (wart hogs), and Sus, the latter containing the domestic pig (see SUS SCROFA).	Phacochoerus,Pigs,Suidae,Warthogs,Wart Hogs,Hog, Wart,Hogs, Wart,Wart Hog
