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 ...

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.

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

On the mechanism of alpha-amylase.
European journal of biochemistry, 2003Two inhibitors, acarbose and cyclodextrins (CD), were used to investigate the active site structure and function of barley alpha-amylase isozymes, AMY1 and AMY2. The hydrolysis of DP 4900-amylose, reduced (r) DP18-maltodextrin and maltoheptaose (catalysed by AMY1 and AMY2) was followed in the absence and in the presence of inhibitor. Without inhibitor,

Endocrine secretion of alpha-amylase by the pancreas
American Journal of Physiology-Gastrointestinal and Liver Physiology, 1981The effect of the gastrointestinal hormone, cholecystokinin-pancreozymin (CCK-PZ), on the flux of alpha-amylase across the basolateral surface of the pancreas into interstitial fluid was measured by following its appearance in the medium bathing whole rabbit pancreas in organ culture.

Bovine pancreatic alpha-amylase binds 1 mol of acarbose (a carbohydrate alpha-amylase inhibitor) per mol at the active site and also binds acarbose nonspecifically. The red kidney bean alpha-amylase inhibitor-bovine pancreatic alpha-amylase complex retained nonspecific binding for acarbose only.

A Nested Alpha-Amylase Gene in Drosophila ananassae
Journal of Molecular Evolution, 2003The amylase gene family of Drosophila ananassae consists in seven copies, scattered on several chromosomal arms. We have evidenced that a member of the family, Amy35, lies within an intron of a gene homologous to the CG14696 gene of D. melanogaster. This nested arrangement seems restricted to the D. ananassae subgroup. The nested and the nest genes are

[The polymorphism of alpha-amylase].
Sudebno-meditsinskaia ekspertiza, 1991Individual phenotypes, phenotypic and genetic frequencies of alpha-amylase enzyme were determined by means of population genetic study. The results of this study revealed absence of genetic linkage between alpha-amylase phenotypes, haptoglobins and serum factor G1m(1) of gammaglobulin system (Gm).
