α-Amylase - Wikipedia
α-Amylase is an enzyme (EC 3.2.1.1; systematic name 4-α-D-glucan glucanohydrolase) that hydrolyses α bonds of large, α-linked polysaccharides, such as starch and glycogen, yielding shorter chains thereof, dextrins, and maltose, through the following biochemical process: [2]
Molecule of the Month: Alpha-amylase - RCSB: PDB-101
Alpha-amylase begins the process of starch digestion. It takes starch chains and breaks them into smaller pieces with two or three glucose units. Two similar types of amylase are made in your body--one is secreted in saliva, where it starts to break down starch grains as you chew, and the other is secreted by the pancreas, where it finishes its ...
Alpha-Amylase - an overview | ScienceDirect Topics
Alpha-amylase (EC 3.2.1.1) is a low-molecular-weight enzyme (approximately 45kDa) that cleaves the alpha-D- (1–4) glycan linkage of starch and glycogen. It has been in use as a diagnostic enzyme longer than any of the other enzymes. It is found in very high concentration in the pancreas in dogs and cats.
α-Amylase: an enzyme specificity found in various families of …
α-Amylase (EC 3.2.1.1) represents the best known amylolytic enzyme. It catalyzes the hydrolysis of α-1,4-glucosidic bonds in starch and related α-glucans. In general, the α-amylase is an enzyme with a broad substrate preference and product ...
Amylase - StatPearls - NCBI Bookshelf - National Center for ...
2023年11月12日 · Amylase enzymes are categorized into 3 main classes—alpha-, beta-, and gamma amylases—each targeting distinct segments of the carbohydrate molecule. Alpha amylase is present in humans, animals, plants, and microbes, whereas beta amylase is primarily found in microbes and plants.
Purification and characterisation of thermostable α-amylases from ...
Microorganisms, especially bacteria have proven to have short generation time and are one of the main sources of α-amylase. Thermophilic, mesophilic, and extremophilic bacteria are good sources for thermostable α-amylases. These enzymes work optimally at extreme temperatures.

2013年2月8日 · α-Amylases (E.C.3.2.1.1) are starch degrading enzymes that catalyses the hydrolysis of internal α-1,4 and α-1,6-glycosidic linkages in starch in low molecular weight products, such as glucose, maltose and maltotriose units.
Plants That Contain Amylase - Sciencing
2021年10月20日 · Alpha-amylase can be found in the pancreas or in saliva. In urine or blood tests, elevated amylase levels indicate potential disease markers. The opposite scenario, reduced amylase levels, can be found in other conditions .
