Descrição geral
Molecular mass: 51-54 kDa.
α-Amylase isolated from porcine pancreas is a glycoprotein. It is a single polypeptide chain of ~475 residues containing two SH groups and four disulfide bridges and a tightly bound Ca2+ necessary for stability. Chloride ions are necessary for activity and stability. The pH range for activity is 5.5 to 8.0, with the pH optimum at 7.

The amylose extender (ae(-)) mutant of maize lacks starch branching enzyme IIb (SBEIIb) activity, resulting in amylopectin with reduced branch point frequency, and longer glucan chains. Recent studies indicate isozymes of soluble starch synthases form high molecular weight complexes with

Starch is the major source of food glucose and its digestion requires small intestinal alpha-glucosidic activities provided by the 2 soluble amylases and 4 enzymes bound to the mucosal surface of enterocytes. Two of these mucosal activities are associated with

Altered monoamine neurotransmission accompanied by hypothalamic-pituitary-adrenal axis dysfunction and autonomic nervous system hyperactivity have been associated with major depressive disorder (MDD). Salivary α-amylase (sAA) is indicative of autonomic activation and reflects central noradrenergic activity. Scarce studies on sAA in MDD

Neurotrophins such as nerve growth factor (NGF) may represent a stress-responsive system complementing the better known neuroendocrine (hypothalamic-pituitary-adrenal axis) and autonomic nervous system, but there is little evidence for NGF response to acute stress in humans because noninvasive measures have

The action pattern of Bacillus licheniformis thermostable α-amylase (BLA) was analyzed using a series of (14)C-labeled and non-labeled maltooligosaccharides from maltose (G2) to maltododecaose (G12). Maltononaose (G9) was the preferred substrate, and yielded the smallest Km=0.36 mM, the highest kcat=12.86
