New malaria enzyme laid bare with help of computer calculations
Using only computers, a research team at Uppsala University in Sweden has managed to reveal both the structure and the function of a newly discovered enzyme from the most dangerous malaria parasite, Plasmodium falciparum. All that was needed was the amino acid sequence of the enzyme. The findings may represent a breakthrough for future... view more... (2004-12-07)
Bigger is better when it comes to the G spot
DRUGS such as Viagra should work for some women- especially if they have a big G spot. This spot, famed for producing spectacular orgasms, turns out to be awash with the enzymes that these drugs act on. The term G spot, coined by Ernest Grafenberg in 1950, refers to an area a few centimetres up inside the vagina on the side closest to a woman`s... view more... (2002-07-03)
UCSD researchers discover cause of rosacea
Doctors can describe the symptoms of rosacea, a common inflammatory skin disease that causes facial redness and affects nearly 14 million Americans. They can tell patients what triggers can worsen their condition: spicy foods, heat, alcohol, even embarrassment. view more (2007-08-06)
Food additive inhibits longevity enzyme in yeast, increases cell toxicity, new study finds
A common additive found in food and cosmetics has been found to inhibit the activity of sirtuins, enzymes associated with lifespan control in yeast and other organisms, according to a new study led by researchers at the University of California, Berkeley. view more (2005-12-16)
Severe sleep apnea may be a risk factor for liver damage
Many patients with obstructive sleep apnea (OSA) are obese and therefore at risk of having fatty liver, a condition in which fat accumulates in the liver cells. But the link between OSA and liver injury independent of weight has yet to be examined. view more (2005-05-25)
'Computer-chemistry' yields new insight into a puzzle of cell division
Duke University biochemists aided by Duke computer scientists and computational chemists have identified the likely way two key enzymes dock in an intricate three-dimensional puzzle-fit to regulate cell division. view more (2005-12-09)
Scientists determine structure of enzyme that disrupts bacterial virulence
A team of biomedical researchers from Brandeis University and the University of Texas at Austin has determined the first 3-dimensional structure of an enzyme that may be pivotal in preventing certain bacterial infections in plants, animals and humans. view more (2005-08-31)
Rehydrate - your RNA needs it

Johns Hopkins scientists have discovered that a deceptively simple sugar is in fact a critical regulator of cells' natural life cycle. view more (2005-09-22)
Penn researchers discover key to how SARS virus infects cells
Researchers from the University of Pennsylvania School of Medicine have found that inhibitors of an enzyme called cathepsin L prevent the SARS (severe acute respiratory syndrome) virus from entering target cells. SARS is caused by an emergent coronavirus. view more (2005-08-02)
Vitamin D inhibits progression of some prostate cancers
Vitamin D can inhibit the spread of prostate cancer cells by limiting the activity of two specific enzymes, University of Rochester Medical Center scientists report. view more (2006-02-09)
Intelligently Designed Molecular Evolution
Evolutionary paths to new therapeutic drugs, as well as a wide assortment of other enzyme products, have been created through, of all things, intelligent design. A team of researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley have developed a technique in which the evolution of an... view more...

Little known DNA repair enzyme may be a tumor suppressor gene
The DNA in our cells is constantly being bombarded by environmental, chemical and cellular insults. Fortunately, our cells contain many enzymes devoted strictly to detecting and repairing any damage caused by these insults. view more (2006-01-04)
Flower power may bring ray of sunshine to cancer sufferers
A mini-protein found in sunflower seeds could be the key to stopping tumors spreading in prostate cancer patients, according to QUT researchers. view more (2008-05-01)
Night of the living enzyme
Inactive enzymes entombed in tiny honeycomb-shaped holes in silica can spring to life, scientists at the Department of Energy's Pacific Northwest National Laboratory have found. view more (2006-11-29)
Bacteria could make new library of cancer drugs that are too complex to create artificially
Researchers at the University of Warwick are examining a way of using bacteria to manufacture a new suite of potential anti-cancer drugs that are difficult to create synthetically on a lab bench. view more (2006-11-01)
Dartmouth researchers find that arsenic triggers unique mechanism in rare leukemia
Dartmouth Medical School (DMS) researchers have identified a new way that arsenite, a form of arsenic, acts in treating a rare cancer known as APL, or acute promyelocytic leukemia. Their study is published in the Jan. 3 issue of the Journal of the National Cancer Institute. view more (2007-01-09)
Plague agent helps UT Southwestern researchers find novel signaling system in cells
The bacterium that causes bubonic plague would seem unlikely to help medical scientists, but researchers at UT Southwestern Medical Center have harnessed it to uncover a new regulatory mechanism that inhibits the immune system. view more (2006-05-26)
