Starch phosphorylase inhibitor from sweet potato.
A protein, starch phosphorylase inhibitor, was purified from the root of sweet potato (Ipomoea batatas [L.] Lam. cv Tainon 65). It had a molecular weight of 250,000 and could be composed of five identical subunits. The isoelectric point of the inhibitor was 4.63. It was a noncompetitive inhibitor toward the sweet potato enzyme with a K(i) value of 1.3 x 10(-6) molar when glucose-1-P was the var...
متن کاملCharacterization of Digestion Resistance Sweet Potato Starch Phosphodiester
Purpose: To analyze the physicochemical properties and in vitro digestibility of sweet potato starch phosphodiester prepared using sodium trimetaphosphate. Methods: The physicochemical properties of sweet potato starch phosphodiester were analyzed by using infrared spectrometry (IR), differential scanning calorimetry (DSC) and rapid visco-analyser (RVA). In addition, an in vitro digestibility m...
متن کاملThe gene structure of starch phosphorylase from sweet potato.
a-Glucan phosphorylases are of key importance among the enzymes controlling the entry of storage polysaccharides into the glycolytic pathway in microbes, animals, and plants. The enzymes catalyze the reversible phosphorolysis of cu-l,4-glucosidic linkages in glucan substrates. Among SP from higher plants, those from potato are best studied. They are classified into L and H types depending on th...
متن کاملBioconversion of wastewater from sweet potato starch production to Paenibacillus polymyxa biofertilizer for tea plants
Wastewater from the sweet potato starch industry is a large source of nutrient-rich substrates. We assessed whether this wastewater could be used to produce Paenibacillus polymyxa biofertilizer for foliar application to tea trees. Using the central composite design methods we experientially determined that the optimal culture conditions for P. polymyxa were pH, 6.5; temperature, 29.0 °C; and in...
متن کاملStarch Phosphorylase of Potato
Cori and his colleagues (l-6) discovered and elucidated the series of reversible chemical reactions by which glucose is transformed into glycogen in animal tissues. These reactions are catalyzed by a group of enzymes, the most fundamental of which is phosphorylase, the enzyme which catalyzes the condensation of glucose-l-phosphate (Cori ester) to starch or glycogen. The properties of phosphoryl...
