Application

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.

Biochem/physiol Actions

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 .

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

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

It has been argued that accumulation of nonstructural carbohydrates triggers a decrease in Rubisco content, which downregulates photosynthesis. However, a decrease in the sink-source ratio in several plant species leads to a decrease in photosynthesis and increases in both structural
