Biochemistry of Human Alpha Amylase Isoenzymes
CRC Critical Reviews in Clinical Laboratory Sciences, 1985The purpose of this article is to review recent literature on the isoenzymes of alpha amylase. Although some studies are cited from the literature of fields other than clinical biochemistry, the aim is to bring together findings that may be of interest to clinical laboratory physicians and scientists.

Alpha-amylase production by toxigenic fungi
Natural Product Research, 2010This study is concerned with the screening of Alternaria alternata (Fr.) Keissler and Alternaria tenuissima (Kunze ex Pers.) Wilts strains for the biosynthesis of alpha-amylases. Nine strains of A. alternata and three strains of A. tenuissima were grown on enzyme production medium (EPM) and potato dextrose agar (PDA) using three pH levels (4.5-6.5 ...

alpha-Amylase in resectable lung cancer
European Respiratory Journal, 1994Biochemical analysis and immunohistochemical techniques support the theory that hyperamylasaemia in lung cancer is due to amylase production in carcinoma cells. The vast majority of amylase-producing carcinomas are adenocarcinomas with amylase isoenzyme similar to the salivary type. This prospective study assesses alpha-amylase expression in resectable

Inhibition of Human Serum Alpha-Amylase Activity
Enzyme, 1983Amylase activity was measured in normal sera and serum of patients with acute pancreatitis and mumps. A significant decrease of enzyme activity in patients with acute pancreatitis was observed after incubation with specific antibody against hog pancreas amylase. A minimal effect of the antibody on normal serum and on that from mumps patients was noted.

Plant alpha-amylase inhibitors and their interaction with insect alpha-amylases.
European journal of biochemistry, 2002Insect pests and pathogens (fungi, bacteria and viruses) are responsible for severe crop losses. Insects feed directly on the plant tissues, while the pathogens lead to damage or death of the plant. Plants have evolved a certain degree of resistance through the production of defence compounds, which may be aproteic, e.g.

Proteinaceous alpha-amylase inhibitors.
Biochimica et biophysica acta, 2004Proteins that inhibit alpha-amylases have been isolated from plants and microorganisms. These inhibitors can have natural roles in the control of endogenous alpha-amylase activity or in defence against pathogens and pests; certain inhibitors are reported to be antinutritional factors.

alpha-Amylase adsorption on starch crystallites.
Biotechnology and bioengineering, 1991The goal of this work was to characterize the adsorption of Bacillus subtills alpha-amylase onto crystalline starchy materials of the B-type polymorph. Monodisperse spherulitic particles (R approximately equal to 5.0 microm), essentially resistant to alpha-amylolysis at 25 degrees C were prepared from short amylose chains (DP(n) approximately equal to ...
