Biased mutagenesis in the N-terminal region by degenerate oligonucleotide gene shuffling enhances secretory expression of barley alpha-amylase 2 in yeast.

Only registered users can translate articles

Recombinant barley alpha-amylase 1 (rAMY1) and 2 (rAMY2), despite 80% sequence identity, are produced in very different amounts of 1.1 and <0.05 mg/l, respectively, by Saccharomyces cerevisiae strain S150-2B. The low yield of AMY2 practically excludes mutational analysis of structure-function

Comparison of standardized patients with high-fidelity simulators for managing stress and improving performance in clinical deterioration: A mixed methods study.

Only registered users can translate articles

BACKGROUND The use of standardized patients in deteriorating patient simulations adds realism that can be valuable for preparing nurse trainees for stress and enhancing their performance during actual patient deterioration. Emotional engagement resulting from increased fidelity can provide

[The adaptational-compensatory reactions of the digestive system during the development of pancreatic atrophy].

Only registered users can translate articles

Adaptive-compensatory processes have been revealed in the digestive system in pancreatic atrophy. These processes promote: a) the compensation of the pancreatic enzymatic insufficiency and of the cavitary digestion decrease by the alpha-amylase adsorbed at the small intestinal epithelium, b) the

[Physiological and biochemical characteristics of changes in pancreatic secretory activity during the development of atrophy in dogs].

Only registered users can translate articles

In pancreatic atrophy the normal digestive dynamics of pancreatic juice volume, concentrations and outputs of proteolytic enzymes, alpha-amylase and bicarbonate are disturbed. The changes of enzymic dynamics are revealed before those of pancreatic juice volume and bicarbonate concentration. The

Gibberellin induces alpha-amylase gene in seed coat of Ipomoea nil immature seeds.

Only registered users can translate articles

Two full-length cDNAs encoding gibberellin 3-oxidases, InGA3ox1 and InGA3ox2, were cloned from developing seeds of morning glory (Ipomoea nil (Pharbitis nil) Choisy cv. Violet) with degenerate-PCR and RACEs. The RNA-blot analysis for these clones revealed that the InGA3ox2 gene was

Potential Bacillus subtilis alpha-amylase-based time-temperature integrators to evaluate pasteurization processes.

Only registered users can translate articles

Thermal inactivation kinetics of Bacillus subtilis alpha-amylase (BSA) in different environmental conditions was studied by performing isothermal experiments. As a response property, residual enzymic activity and residual heat of enzyme deterioration were chosen. A comparison of processing values

Staling of white wheat bread crumb and effect of maltogenic α-amylases. Part 1: Spatial distribution and kinetic modeling of hardness and resilience.

Only registered users can translate articles

Bread staling is one of the most costly food deterioration processes. This study presents an in-depth, multivariate, statistical assessment of the differences in the staling process of white wheat bread as a function of storage time, usage of maltogenic α-amylases and spatial position in the loaf by

amyP, a reporter gene to study strain degeneration in Clostridium acetobutylicum ATCC 824.

Only registered users can translate articles

Clostridium acetobutylicum produces an extracellular alpha-amylase when grown on glucose as the sole carbon source. This enzyme was previously characterized from a biochemical point of view but its encoding gene was never identified. The 2283-bp amyP gene encodes a 83013-Da mature protein with an

[Device for measuring salivary alpha-amylase--application for pain assessment].

Only registered users can translate articles

The salivary enzyme alpha-amylase is an established non-invasive marker of psychological and physiological stress. Since there are positive correlations between salivary alpha-amylase secretion and sympathetic parameter increment during stress, salivary alpha-amylase might be an indicator of

Cloning and expression of the Clostridium thermohydrosulfuricum alpha-amylase-pullulanase gene in Escherichia coli.

Only registered users can translate articles

An alpha-amylase-pullulanase gene from Clostridium thermohydrosulfuricum DSM 3783 was cloned in Escherichia coli on a 7.0 kb EcoRI fragment using a lambda vector. The gene produced, from an indigenous promoter, active thermostable alpha-amylase-pullulanase, seemingly mostly a soluble intracellular

Relationship of ribonucleic Acid metabolism in embryo and aleurone to alpha-amylase synthesis in barley.

Only registered users can translate articles

RNA metabolism of embryo and aleurone of barley grains (Hordeum vulgare L. cv. Himalaya) was studied to elucidate the role of these tissues in the control of alpha-amylase synthesis and germination. The extent of (3)H-uridine incorporated into various RNA classes of the embryo during the first 12

Mildly disturbed hepatic and pancreatic function during early abstention from alcohol is associated with brain atrophy and with disturbed psychometric performance.

Only registered users can translate articles

OBJECTIVE To investigate the relation of liver status and pancreatic function to disorders of the central nervous system during early abstention from alcohol. METHODS Sixty-seven alcohol-dependent patients (47 male) with a mean age of 42.3 +/- 12.5 years, were assessed by clinical history, abdominal

Overexpression in Escherichia coli of chemically synthesized gene for active 0.19 alpha-amylase inhibitor from wheat kernel.

Only registered users can translate articles

A synthetic gene encoding 0.19 alpha-amylase inhibitor (alpha-AI) from wheat kernel was obtained by enzymatic assembly of 18 oligodeoxynucleotides which were chemically synthesized. The synthetic gene was introduced into vector pET15b for expression in Escherichia coli BL21(DE3) under the control of

Suppression of α-amylase genes improves quality of rice grain ripened under high temperature.

Only registered users can translate articles

High temperature impairs rice (Oryza sativa) grain filling by inhibiting the deposition of storage materials such as starch, resulting in mature grains with a chalky appearance, currently a major problem for rice farming in Asian countries. Such deterioration of grain quality is accompanied by the

Beneficial effects of fermented sardinelle protein hydrolysates on hypercaloric diet induced hyperglycemia, oxidative stress and deterioration of kidney function in wistar rats.

Only registered users can translate articles

This study investigated the potential effects of fermented sardinelle protein hydrolysates (FSPHs) obtained by two proteolytic bacteria, Bacillus subtilis A26 (FSPH-A26) and Bacillus amyloliquefaciens An6 (FSPH-An6), on hypercaloric diet (HCD) induced hyperglycemia and oxidative stress in rats.
