Scientists demonstrate feasibility of preventing malaria parasite from becoming sexually mature
Researchers have demonstrated the possibility of preventing the human malaria parasite, Plasmodium falciparum, which is responsible for more than a million malaria deaths a year, from becoming sexually mature. view more (2008-06-03)
Researchers Create Model of Cancer-Preventing Enzyme, Study How It Works
Proline dehydrogenase is important because it plays a role in apoptosis, the process of cell death, by enabling the creation of superoxide, a highly reactive electron-rich oxygen species. view more (2007-05-14)
SUMO protein guides chromatin remodeler to suppress genes
In an in vitro study, led by Grace Gill, PhD, Tufts University School of Medicine, researchers discovered how a protein called SUMO (Small Ubiquitin-related Modifier) guides an enzyme complex that alters the structure of chromatin to regulate expression of genes. view more (2009-04-28)
Scientists learn structure of enzyme in unusual virus
Biologists have determined the three-dimensional structure of an unusual viral enzyme that is required in the assembly of new viruses. view more (2007-09-18)
That '4 hour erection': new discovery may help prevent a complication of priapism
For men coping with painful erections lasting for long periods of time, or priapism, new research published online in The FASEB Journal (http://www.fasebj.org) offers hope. view more (2009-10-27)
Gladstone scientists reveal that fat synthesizing enzyme is key to healthy skin and hair
Scientists at the Gladstone Institutes of Cardiovascular Disease (GICD) have found that an enzyme associated with the synthesis of fat in the body is also an element in healthy skin and hair. view more (2009-02-13)

Nature's weapon against nerve agents
An enzyme found naturally in the blood could help protect soldiers against the effects of the deadly nerve agent sarin, reports Cath O'Driscoll in the Society of Chemical Industry's magazine Chemistry & Industry, the magazine of the SCI. view more (2007-07-30)
Study details structural changes of a key catalytic enzyme
Enzymes are complex proteins capable of catalyzing specific biochemical reactions in cells. view more (2006-09-21)
Biochemical 'on-switch' could solve protein purification challenge
Drugs based on engineered proteins represent a new frontier for pharmaceutical makers. Even after they discover a protein that may form the basis of the next wonder drug, however, they have to confront a long-standing problem: how to produce large quantities of the protein in a highly pure state. view more (2009-10-23)
UT Knoxville and ORNL researchers reveal key to how bacteria clear mercury pollution
Mercury pollution is a persistent problem in the environment. Human activity has lead to increasingly large accumulations of the toxic chemical, especially in waterways, where fish and shellfish tend to act as sponges for the heavy metal. view more (2009-10-02)
Texas A&M Researchers Examine How Viruses Destroy Bacteria
Viruses are well known for attacking humans and animals, but some viruses instead attack bacteria. Texas A&M University researchers are exploring how hungry viruses, armed with transformer-like weapons, attack bacteria, which may aid in the treatment of bacterial infections. view more (2009-11-19)
Using evolution, UW team creates a template for many new therapeutic agents
By guiding an enzyme down a new evolutionary pathway, a team of University of Wisconsin-Madison researchers has created a new form of an enzyme capable of producing a range of potential new therapeutic agents with anticancer and antibiotic properties. view more (2007-09-10)
Scientists develop new treatments for Alzheimer's disease
Scientists at the University of Liverpool have created a new chemical compound that could be developed into a drug treatment for Alzheimer's disease. view more (2006-10-27)
DNA size a crucial factor in genetic mutations, study finds
Researchers at Stanford University have created a larger-than-normal DNA molecule that is copied almost as efficiently as natural DNA. view more (2005-10-27)
Multiple sclerosis research charges ahead with new mouse model of disease
A new study highlights the role of a charge-switching enzyme in nervous system deficits characteristic of multiple sclerosis and other related neurological illness. view more (2008-11-06)
Study says normal but out-of-control enzyme may be culprit that signals some cells to become cancer
Working with human colorectal cancer cells, a University of Minnesota team, led by cancer biologists Zigang Dong and Ann Bode, has found the potential culprit among a network of enzymes that relay signals inside cells to regulate such functions as cell growth, cancer development and programmed cell death. view more (2007-08-01)
Atomic-resolution views suggest function of enzyme that regulates light-detecting signals in eye
An atomic-resolution view of an enzyme found only in the eye has given researchers at the University of Washington (UW) clues about how this enzyme, essential to vision, is activated. view more (2008-10-08)
New UW study offers strategy for treatment of fatal nervous system disorder
Working with mice, University of Wisconsin-Madison researchers have developed the basis for a therapeutic strategy that could provide hope for children afflicted with Krabbe's disease, a fatal nervous system disorder. view more (2005-12-13)
New therapy may mean less dietary restrictions for celiac sufferers
Scientists have discovered what may be a successful non-dietary therapy for celiac sprue, an inherited inflammatory disorder of the small intestine that impacts an estimated 1 in 200 people around the world. view more (2006-06-26)
