WebApr 11, 2024 · Fructose-1,6-bisphosphate (F-1,6-BP) is an important intermediate in glucose metabolism, particularly in cancer. Gluconeogenesis and glycolysis require fructose-1,6-bisphosphonates 1 (FBP1) and fructose-bisphosphate aldolase A (ALDOA), which participate in F-1,6-BP conversion. ...

WebFructose bisphosphatase deficiency. Fructose 1,6-bisphosphate. Specialty. Endocrinology. In fructose bisphosphatase deficiency, there is not enough fructose bisphosphatase for gluconeogenesis to occur correctly. Glycolysis (the breakdown of glucose) will still work, as it does not use this enzyme.
Fructose 1,6-bisphosphatase is also a key player in treating type 2 diabetes. In this disease, hyperglycemia causes many serious problems, and treatments often focus on lowering blood sugar levels. Gluconeogenesis in the liver is a major cause of glucose overproduction in these patients, and so inhibition of … See more The enzyme fructose bisphosphatase (EC 3.1.3.11; systematic name D-fructose-1,6-bisphosphate 1-phosphohydrolase) catalyses the conversion of fructose-1,6-bisphosphate to fructose 6-phosphate in gluconeogenesis and … See more The fold of fructose-1,6-bisphosphatase from pigs was noted to be identical to that of inositol-1-phosphatase (IMPase).
