RCSB PDB - 1HNY: The structure of human pancreatic alpha-amylase …
1995年6月28日 · The structure of human pancreatic alpha-amylase has been determined to 1.8 A resolution using X-ray diffraction techniques. This enzyme is found to be composed of three structural domains. The largest is Domain A (residues 1-99, 169-404), which forms a central eight-stranded parallel beta-barrel, to one end of which are located the active site ...

3D Structure of Human α-Amylase - Davidson
On this page, you can see the structure of human salivary α-amylase. In general, α-amylase is an enzyme that catalyzes the hydrolysis of α-1,4 gulcan linkages in starch. It is found widely among all three kingdoms of life. The following will highlight important structural aspects related to the function of α-amylase.
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 ...
Amylase - Pancreapedia
2019年3月25日 · The structure of human amylase protein is known and contains three domains termed A, B, and C starting at the amino terminal (9). The active site is located the A domain; calcium binds to the B domain and may stabilize the active site (10).
The α-amylase structural model, image was downloaded from the Protein …
Soluble alpha-amylases play an important role in the catabolism of polysaccharides. In this work, we show that the enzyme can interact with the lipid membrane and further alter its mechanical...

CDD Conserved Protein Domain Family: Alpha-amylase
2022年10月17日 · Alpha amylase is classified as family 13 of the glycosyl hydrolases. The structure is an 8 stranded alpha/beta barrel containing the active site, interrupted by a ~70 a.a. calcium-binding domain protruding between beta strand 3 and alpha helix 3, and a carboxyl-terminal Greek key beta-barrel domain.
