Applicazioni

Amyloglucosidase is used to hydrolyze α-D-glucosides. It may be used in the brewing of beer and in the production of bread and juices. Amyloglucosidase, from Rhizopus sp., has been used to study the cleavage of oligosaccharides during ER-associated degradation of proteins (ERAD). The enzyme has been used in the glycosylation of N-vanillyl-nonanamide to form a water-soluble component with pharmacological applications. The glycogen was estimated in stipe residue of Coprinus cinereus by treating with amyloglucosidase and measuring the amount of glucose produced.

Azioni biochim/fisiol

Amyloglucosidases are capable of hydrolyzing the α-D-(1-4), the α-D-(1-6), and the α-D-(1-3) glucosidic bonds of oligosaccharides .

Definizione di unità

One unit will liberate 1.0 mg of glucose from starch in 3 min at pH 4.5 at 55 °C.

To clarify whether excessive accumulation of total non-structural carbohydrate (TNC) causes down-regulation of photosynthesis in Raphanus sativus, we manipulated sink-source balance to alter TNC levels in source leaves and examined its effects on photosynthetic characteristics, whole-plant biomass allocation and anatomical

In Saccharomyces cerevisiae, proteins with misfolded lumenal, membrane, and cytoplasmic domains are cleared from the endoplasmic reticulum (ER) by ER-associated degradation (ERAD)-L, -M, and -C, respectively. ERAD-L is N-glycan-dependent and is characterized by ER mannosidase (Mns1p) and ER mannosidase-like protein

Enzymatic syntheses of N-vanillyl-nonanamide, 1, glycosides with D-glucose, 2, D-galactose, 3, D-mannose, 4, D-ribose, 5, maltose, 6, and lactose, 7, were carried out using amyloglucosidase from Rhizopus and beta-glucosidase from sweet almond. The latter catalysed the syntheses of N-vanillyl-nonanamide glycosides

To determine the effects of elevated CO(2) concentration ([CO(2)]) on the temperature-dependent photosynthetic properties, we measured gas exchange and chlorophyll fluorescence at various leaf temperatures (15, 20, 25, 30, 35 and 40°C) in 1-year-old seedlings of the Japanese white birch

Sink-source imbalance could cause an accumulation of total non-structural carbohydrates (TNC; soluble sugar and starch) in source leaves. We aimed to clarify interspecific differences in how sink-source imbalance and TNC causes the downregulation of photosynthesis among three legume plants. The
