Sugar-coated antibiotics
Researchers from the John Innes Centre and the University of East Anglia have recently elucidated the structure and function of an enzyme which is involved in decorating antibiotics with sugar molecules. view more (2008-05-29)
Enzyme promotes fat formation
The enzyme TPPII may contribute to obesity by stimulating the formation of fat cells, suggests a study in EMBO reports this week. The enzyme, TPPII, has previously been linked to making people feel hungry, but Jonathan Graff and colleagues now show that it may be even more deeply involved in causing obesity. view more (2007-10-12)
The secret behind silkworm's hardy stomachs
Silkworms have a unique ability to eat toxic mulberry leaves without feeling ill, and researchers have come one step closer to understanding why: silkworms contain a special digestive enzyme that is not affected by mulberry's toxic chemicals. view more (2008-05-28)
UAB research could improve the prognosis and treatment of lung cancer
A group of scientists led by Professor Xavier Parés of the Department of Biochemistry and Molecular Biology at Universitat Autònoma de Barcelona, has published a research on AKR1B10, an enzyme that is detected in large quantities only in lung cancers, particularly those caused by smoking. view more (2008-01-08)
Gene variant linked to risk of stroke and heart attack for those on Plavix
A new study reports that a gene variant carried by about a third of the population plays a major role in this group's response to an anti-clotting medicine, clopidogrel (Plavix). People with the variant produce a defective version of the CYP2C19 enzyme and are less able to activate the drug. view more (2009-08-26)
The structure of resistance
A team of scientists from the University Paris Descartes has solved the structure of two proteins that allow bacteria to gain resistance to multiple types of antibiotics, according to a report in EMBO reports this month. view more (2008-02-25)
Gene-regulating enzyme is also a target for anti-depressive drugs
In 2005, professor Ramin Shiekhattar, Ph.D., at The Wistar Institute and his colleagues reported details about an enzyme involved in appropriately repressing sets of neuronal genes in non-neuronal cells. view more (2006-06-26)
Convincing results: Stopping the spread of cancer in the body
A team of Danish researchers have discovered that by blocking a specific enzyme, it is possible to check the spread of cancer in the body. This finding may be the first step towards preventing deaths due to cancer spreading to other parts of the body. The discovery may also help reduce the amount of chemotherapy used. view more (2004-11-22)
Discovery of new protein could provide new understanding of male fertility
Scientists have discovered a new enzyme involved in the degradation of proteins inside cells, a process that helps eliminate or recycle proteins that are no longer needed. view more (2007-08-03)
'Corrective genes' closer thanks to enzyme modification
Scientists from the Université de Montréal and McGill University have re-engineered a human enzyme, a protein that accelerates chemical reactions within the human body, to become highly resistant to harmful agents such as chemotherapy, according to a new study published in The Journal of Biological Chemistry. view more (2009-07-29)
Worth a thousand words: Hopkins researchers paint picture of cancer-promoting culprit
They say that a picture can be worth a thousand words. This especially is true for describing the structures of molecules that function to promote cancer. Researchers at Johns Hopkins have built a three-dimensional picture of an enzyme often mutated in many types of cancers. view more (2008-01-07)
UCLA researchers reconstitute enzyme that synthesizes cholesterol drug lovastatin
Researchers from the UCLA Henry Samueli School of Engineering and Applied Science have for the first time successfully reconstituted in the laboratory the enzyme responsible for producing the blockbuster cholesterol-lowering drug lovastatin. view more (2009-11-04)
New inhibitor has potential as cancer drug
Laboratory experiments have previously shown that cancer cells overproduce an enzyme, heparanase, which splits the body's own polysaccharide heparan sulfate into shorter fragments. view more (2007-10-23)
Gladstone scientists reveal key enzyme in fat absorption
Scientists at the Gladstone Institutes of Cardiovascular Disease (GICD) have found that a key enzyme involved in absorbing fat may also be a key to reducing it. view more (2009-03-16)
Enzyme discovery sheds light on vitamin D
Surprising findings by Queen's researchers have shed new light on how the "sunshine vitamin" D - increasingly used to treat and prevent cancer and other diseases - is broken down by our bodies. view more (2007-07-25)
Enzyme doesn't act alone in atrial fibrillation
An overactive enzyme is behind a leaky calcium channel that plays a role in the development of atrial fibrillation, which is the most common cardiac arrhythmia that is responsible for a third of all strokes. view more (2009-06-18)
Opening and closing the genome
At any given time, most of the roughly 30,000 genes that constitute the human genome are inactive, or repressed, closed to the cellular machinery that transcribes genes into the proteins of the body. view more (2007-02-26)
Success for fishy scientist
Scallops, oysters and mussels - the best of fare Scotland`s kitchens have resulted in a top Parisian award for a researcher from the University of Dundee. Matthew Gubbins is not a chef but a scientific expert on toxicity in shellfish. Matthew (26) has scooped the Daniel Jouvance award for his work on how shellfish become toxic and then lose their... view more... (2002-07-18)
Unlocking the function of enzymes
Fitting a key into a lock may seem like a simple task, but researchers at Texas A&M University are using a method that involves testing thousands of keys to unlock the functions of enzymes, and their findings could open the door for new targets for drug designs. view more (2007-11-07)
Towards the mechanism of cell respiration
Researchers at the Institute of Biotechnology of the University of Helsinki have for the first time identified an internal electron transfer reaction that initiates the proton pump mechanism of the respiratory enzyme. view more (2006-04-06)
