Rationale: Fructose-1, 6-bisphosphatase 1 (FBP1), a rate-limiting enzyme in gluconeogenesis, was recently shown to be a tumor suppressor and could mediate the activities of multiple transcriptional factors via its non-canonical functions. Origine: Humain. Gardemann A 1 ... Fructose-1,6-bisphosphatase is allosterically inhibited by fructose-6-phosphate in a sigmoidal fashion, allowing a fine control of the enzyme by its product. fructose-1,6-bisphosphatase. Cette consommation d'énergie rend cette étape irréversible, et constitue un point de régulation majeur de la vitesse de la glycolyse. Les fructose-1,6-bisphosphatases trouvées chez les Firmicutes, des bactéries à Gram positif et faible taux de GC, ne montrent pas de similitudes séquentielles significatives avec les enzymes d'autres organismes.

(2006) "Localization and regulation of muscle fructose-1,6-bisphosphatase, the key enzyme of glyconeogenesis" Adv. 284, 27037 - 27041. Two different paralogs exist in humans; FBP1 is found in the liver, and FBP2 is found in muscle. Its main role is in glycolysis instead of gluconeogenesis, but its substrate is the same as FBPase's, so its activity affects that of FBPase in gluconeogenesis. Une étude structurelle a montré que le groupe FBPase V possède un repliement inhabituel pour une phosphatase d'ose, avec un arrangement de quatre couches en configuration sandwich alpha–bêta–bêta–alpha, par opposition à la configuration plus courante en sandwich alpha–bêta–alpha–bêta–alpha[2]. Fructose 1,6-bisphosphatase also plays a key role in hibernation, which requires strict regulation of metabolic processes to facilitate entry into hibernation, maintenance, arousal from hibernation, and adjustments to allow long-term dormancy.
