Russian biologists from Moscow State University have recently published a study devoted to the structure of part of the telomerase enzyme. One of the authors noted that the study will help develop treatments that can both stimulate or inhibit the enzyme's activity. Telomerase is required for the proper ...

WASHINGTON, April 2 (Xinhua) -- American and Chinese scientists have identified how a multi-functional enzyme works to fight diseases including HIV infection and autoimmune disorders. The study, published on Monday in the journal Proceedings of the National Academy of Sciences, has detailed how ...

Eddie the Enzyme is ready to break down food and take on the competition in pancreatic enzyme products. The spokescharacter, created by Allergan, works in “interdigestive space” with a friendly message about the need for prescription enzymes for people with exocrine pancreative insufficiency (EPI).

The new study shows that the synthetic compound is capable of inhibiting the activities of several DNA-processing enzymes, including the 'integrase' used by the Human Immunodeficiency Virus (HIV) to insert its genome into that of its host cell. The successful demonstration of the efficacy of the synthetic ...

For more than eight decades, National Enzyme Company has been working in the dietary supplement business. Dr. Edward Howell started NEC in 1932 with a vision of replacing the enzymes lost in cooking and he created enzyme supplements, according to the company's website. His enzyme ...

"Even if we know exactly what an enzyme does," Li says, "we still don't have a sense for how much of that protein the cell will make. Thinking about biochemical pathways is even more complicated. If we gave biochemists three enzymes in a pathway that, for example, break down sugar into energy, they ...

Crystal structure of the host enzyme, Acyloxyacyl Hydrolase (AOAH), in complex with lipopolysaccharide (LPS) shown in grey sticks, which is a potent bacterial toxin. The figure shows one of the six fatty acid chains of LPS swung out and …more. Biochemists from McGill University are getting a good look at ...

Protein Hydrolysis Enzymes Market Report covers the comprehensive market, vendor landscape, present scenario, and the growth prospects of the Protein Hydrolysis Enzymes for 2017-2022. report, consists of various factors such as definitions, applications, and classifications. Global Sales Volume, Sales ...

... researchers at UC Davis' Siegel Lab are conducting a series of lab experiments on native wheat enzymes in several varieties of wheat to determine their activity and sensitivity to heat. The study will examine a series of mutations to find one that could be injected into the enzyme to make it heat stable.

Researchers in Hong Kong may have identified a factor behind the rise of the superbugs after discovering a type of enzyme that can break down antibiotics. The team from the Hong Kong University of Science and Technology said the find could help pharmaceutical companies develop more effective drugs ...

Scientists at UC Berkeley have created a protein mat that can absorb chemical pollution, providing a breakthrough in scientific research that could potentially be applied to war zones and contaminated sites. The applications of this groundbreaking discovery include degrading pollutants such as pesticides ...

Sitting inside the Schwann cells, an enzyme known as fatty acid synthase (FASN) acts as a central "switch" in the process of synthesising lipids. The team found that this enzyme is essential for the correct composition of lipids in the insulating layers, for the cells to start myelination, and for the healthy growth ...

Unactivated alkenes have been transformed into four stereoisomers of cyclopropane by a group of enzymes – the first example of a biocatalytic reaction performed by haem proteins that does not occur in nature. The set of biocatalysts could serve as starting points for 'green' synthesis of cyclopropanated ...

But the exact influence of the molecules to the enzyme is not yet fully understood. For that reason, Ben Bdira studied these different molecules to produce a molecule that could be used against Gaucher's disease. In the future, he hopes this knowledge can be used to reduce the effects of metabolic diseases ...

... the mechanism appears to differ from that of the bacterial version of the enzyme, suggesting that it could be possible to design antibiotics that selectively block the bacterial enzyme. "People have been trying to figure out whether there is something different enough that you could inhibit bacterial enzymes ...

The research findings may prove useful in the future for developing new antibiotics and in industrial contexts where it is important to be able to switch enzymes on and off in the production of chemicals. "This function could potentially be used to stick other unrelated proteins together to prevent them from ...

Instead, they are first synthesized with chains of amino acids that block their activity until they are removed by enzymes called "proprotein convertases" (PCs). This family of enzymes plays significant but very different roles in various cancers, and regulating the activity of PCs could help develop cancer ...

"By considering these key enzymes and figuring out what are the differences and similarities, we can see if there's anything in the bacterial enzyme that could be targeted with small-molecule drugs." Drennan is one of the senior authors of the study, which appears in the Feb. 20 issue of the journal eLife.

Enzymes are proteins that speed up or catalyze a reaction in living organisms. Bacteria can produce enzymes that make them resistant to antibiotics. Specifically, the TEM beta-lactamase enzyme enables bacteria to develop a resistance to beta-lactam antibiotics, such as penicillin and cephalosporins.

Knocking back an enzyme swept mouse brains clean of protein globs that are a sign of Alzheimer's disease. Reducing the enzyme is known to keep these nerve-damaging plaques from forming. But the disappearance of existing plaques was unexpected, researchers report online February 14 in the ...

While he notes that "[t]his is probably not the only pathway accounting for energy expenditure in fasting or obesity," he adds, "[T]his information provides new insight into how we might develop drugs that inhibit TBK1 or other enzymes involved in metabolism." Still, the researchers note that taking special ...

Under optimum conditions, enzymes can work quickly — up to 20,000 times per second — to speed up the chemical process of fermentation. Most of the enzymes in forage inoculants break down complex materials into simpler materials. Each type of enzyme contributes differently to the ensiling process.

With some engineering in the lab, a quartet of iron-containing heme proteins from microbes can convert inert alkenes into each possible stereoisomer of cyclopropanes, which are valuable motifs in medicinally active compounds (ACS Cent. Sci. 2018, DOI: 10.1021/acscentsci.7b00548). Previous ...

In both nature and industrial processes, enzymes from this family are among the most significant enzymes for breaking down cellulose. A projected 2,000-ton-per-day cellulosic ethanol plant could potentially use up to 5,000 tons of enzyme per year, and half of that enzyme cocktail could be from this enzyme ...
