Determining the structure of OST was not easy: to start with, Jilliane Eyring, the third lead author of the report, modified the yeast cells so that the enzyme could be targeted and purified. Wild first had to extract the enzyme, which is embedded in a membrane in the cell, from large quantities of these yeast ...
One difficulty in understanding how de novo DNA methylation works is that the structures of these enzymes are not known. The UC Riverside-led team has now solved the crystal structure for substrate-bound DNMT3A. This breakthrough reveals how the enzyme recognizes and methylates its substrates ...

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 ...
Sometimes the body doesn't make enough digestive enzymes. This can slow the digestion process and lead to uncomfortable symptoms. For example, if you don't make enough of the enzyme lactase, you'll have a hard time digesting lactose -- the sugar in milk and milk-based products. "If you don't have ...
Dr. Wolfgang Hess from the University of Freiburg have now identified an enzyme, a special pair of RNA scissors, which is involved in CRISPR/Cas systems and the correct regulation of gene expression -- in other words, in reading genes and translating their information into proteins. The researchers have ...

The deadly ebola virus incorporates a cellular enzyme into its virus particles, facilitating the infection to the target cells, according to new research published in the journal PLOS Pathogens. When this enzyme Xkr8 is activated, it flips a phospholipid called phosphatidylserine (PS) from the inner layer of the ...
"ADM is getting into enzymes," she told FeedNavigator. "The first enzyme that we're focusing on is an NSP enzyme - what that means is when we include higher levels of fiber [in feeds] there are portions of those ingredients that the pig or chicken cannot utilize well, so this is just like phytase, this is an ...
"Now we've worked out how to crystallise these enzymes and how they work, we're looking how to use bacteria to cheaply create highly efficient enzymes." Dr. Mylne led the team of Australian and US scientists that revealed the enzyme process through the Australian Research Council-supported study ...
Ann Donnelly was utterly confused the first time she examined her protein. On all counts, it behaved like an enzyme--a protein catalyst that speeds up biological reactions in cells. One could argue that enzymes, sculpted by eons of evolution, make life possible. There was just one problem: her protein ...

scientists at the University of Bonn have clarified a surprising dual function of ceramide synthase. The enzyme not only catalyzes a central step of the production of vital lipids. It also has the ability to turn genes involved in lipid metabolism on or off. The study is being published in the journal Cell Reports.
Supplementing certain digestive enzymes can be helpful for digestion problems. However, since there are so many enzymes that play a role in digestion, and so many available products with varying degrees of purity, reasonable claims, etc., it is not easy for a consumer to try to choose their own enzyme ...
... enzymes that produce them have barely changed over many millions of years of evolution. For example, the ceramide synthase of the Drosophila fruit fly is very similar to that of humans. However, in contrast to the insect which is only a few millimeters in size, we have six different variants of the enzyme.
An international group of researchers demonstrated that the enzyme EXD2 has a key role in the production of mitochondrial protein. The study, "EXD2 governs germ stem cell homeostasis and lifespan by promoting mitoribosome integrity and translation," was published in the journal Nature cell biology.

ADM's initial focus for the upcoming enzyme work will be on production for monogastric animals, he said. "ADM has vast experience and expertise in the area of feed and feed ingredients - both on the macro and the micro level," he said of the focus for the work. "We are able to approach the enzymes ...
These proteins were then screened to see if any could rescue E. coli that were missing a gene essential to survival. Three proteins succeeded, which indicates that they compensated for the missing gene's essential function. But they did not do so by acting as a catalyst (meaning they weren't enzymes).
The tiny molecule can change how proteins function. But new research featured in Molecular Cell suggests supplementing nitric oxide -- NO -- is only the first step. Researchers have discovered previously unknown enzymes in the body that convert NO into "stopgap" molecules -- SNOs -- that then modulate ...
What happens when you chuck an active enzyme into the wrong solvent? Well, it stops working (or at the very least, it stops working as well as it did). And how do you know which one is the wrong solvent? Why, those are the ones that make it stop working. That round trip is to illustrate that there's often ...
Atsushi Matsuzawa at Tohoku University and colleagues in Japan used gene silencing techniques and cell culture studies to investigate how molecules regulate an enzyme known as apoptosis signal-regulating kinase 1 (ASK1). Irregular ASK1 activation is linked to some cancers, and inflammatory and ...
Low concentrations of tannins caused changes in enzyme conformation thereby increasing its catalytic activity. In contrast, high concentrations of tannins show the opposite effect by decreasing the catalytic activity of enzymes. Furthermore, Adamczyk and colleagues also showed that tannins interact not ...

DHODH also binds a lipid in the cell's mitochondrial respiratory chain complex, suggesting the enzyme might use special lipids to locate the correct binding ...
"Each step has an enzyme that catalyzes it, because otherwise those reactions wouldn't go fast enough for life to exist. An enzyme is a protein that is a catalyst. They're the best catalysts in the universe because evolution has spent billions of years selecting them. enzymes can increase the speed of a ...
Syn-F4 "not only replaced the function of a naturally evolved enzyme but, remarkably, used a completely different sequence, structure, and mechanism to do so," adds Burckhard Seelig of the University of Minnesota.

Unfortunately, the enzyme is also extremely fussy about how it operates, in part as a result of the evolutionary events that put it in plants in the first place. But now, a team of German scientists has figured out how to get the enzyme to work in the standard lab bacteria, E. coli, opening the door slightly to ...
