Amylolytic enzymes are a class of enzymes that degrade starch and other polysaccharides. For example, α-amylase hydrolyzes the α-1,4-glucosidic bonds within starch molecules, thereby breaking them down into shorter chain-like sugar molecules such as maltose, dextrin, and glucose. β-amylase acts on the non-reducing end of the starch molecule and hydrolyzes it into maltose. The main function of glucoamylase is to hydrolyze the non-reducing terminal α-1,4-glucosidic bond of starch molecules and break them into glucose molecules, and it is an important digestive enzyme and industrial enzyme. These different types of amylolytic enzymes play important roles in food processing, winemaking, biofuels, and other fields, promoting the degradation and utilization of starch. Each type of enzyme works under specific conditions, working together to complete the complete degradation process of starch molecules. Creative Biolabs has rich experience in Enzyme Activity Assessment services. We design appropriate experimental plans and conduct reliable enzyme activity tests according to client needs, such as Cellulases, Cellulolytic Enzymes, and amylolytic enzymes.
We provide high-level analysis for many types of amylolytic enzyme activity through the following steps, including α-amylase, β-amylase, and glucoamylase.
Before performing amylolytic enzyme activity analysis, sample pretreatment is crucial. We perform appropriate pretreatment of the samples according to the experimental purpose. For example: We centrifuge samples to remove impurities or solid particles. The sample is then diluted to an appropriate concentration range to ensure the accuracy of the experimental results.
We add amylolytic enzyme solution and mix substrate solution (usually containing starch) in appropriate buffers and mix them thoroughly in the same system. We control experimental conditions, such as temperature, pH, and reaction time, to start the catalytic reaction of amylolytic enzymes. The reaction is then terminated by adding an appropriate reaction stop reagent, and the reaction mixture is centrifuged to obtain a clear supernatant or precipitate for subsequent analysis.
We evaluate amylolytic enzyme activity by measuring the products generated by the reaction or the substrate consumed. Different methods differ in terms of operational procedures, sensitivity, and quantitative accuracy. Common measurement methods include:
Combined with a standard curve or a specific calculation formula, we convert the measured data into amylolytic enzyme activity units (the amount of product released or the amount of substrate consumed per unit time). Then we perform statistical analysis on the experimental results and deliver the analysis results to the client in the form of a report.
Creative Biolabs has experienced and professional teams that accurately perform enzyme activity analysis and interpret the results. We are equipped with advanced laboratory equipment, such as high-performance liquid chromatography, mass spectrometer, etc., to ensure accurate and rapid analysis of amylolytic enzyme activity. Don't hesitate to contact us promptly if you need high-quality amylolytic enzyme activity analysis, we are your best choice.
α-Amylase is an endoglucanase that works by cleaving α-1,4-glycosidic bonds within starch to produce shorter sugar molecules. Glucoamylase is an exoglucanase that releases the monosaccharide glucose from the non-reducing end of starch. The hydrolytic activity of α- or glucoamylase is generally measured by measuring an increase in the amount of product (reducing sugars) or a decrease in the amount of substrate. The authors customized a protocol for measuring amylolytic enzyme activity. They took advantage of the micro-thermal cycler's ability to accurately and quickly control temperature and conducted micro-measurements on the activities of α-amylase and glucoamylase in the thermal cycler through the Somogyi-Nelson test (SNT) and the starch iodine test (SIT). The results showed that microSIT was more sensitive in detecting endoglucanase activity, while microSNT was more sensitive in detecting exoglucanase activity. This assay scheme reduced reagent and sample volumes, further improved the sensitivity of the assay, and helped develop new biocatalysts and analyzed sugar-containing samples.
