New theory from University of Leicester scientists underpins drug development and food processing
Scientists at the University of Leicester have shown that the textbook explanation of how enzymes work is wrong - at least for some enzymes. view more (2004-10-05)
Dynamic molecular mechanism to keep brain activity stable
In the brain, many types of synaptic proteins are spatio-temporally regulated to maintain synaptic activity at a constant level. view more (2009-07-13)
Impersonating nature

Rushing fireball developed its own form of sugar digestion
Microbiologists from Wageningen have discovered a strange form of digestion in an exotic microorganism. The rushing fireball, Latin name Pyrococcus furiosus, has reinvented the wheel for several steps of sugar digestion. Pyrococcus furiosus, which was discovered 15 years ago on an Italian volcanic island, digests sugar somewhat differently from... view more... (2002-04-18)
Study could help target new pancreatitis treatments
Pancreatitis is often a fatal condition, in which the pancreas digests itself and surrounding tissue. view more (2009-06-30)
MGH researchers describe new way to identify, evolve novel enzymes
The intricate interplay of proteins and other chemicals that underlies most biological activities requires the participation of enzymes, specialized molecules that accelerate chemical reactions between molecules. view more (2007-08-16)
Pick your COX partners
Researchers at the University of Pennsylvania School of Medicine and Queen's University, Ontario, Canada report in the online edition of Nature Medicine this week that the COX enzymes — well-known for their contrasting role in cardiovascular biology — interact physically to form a previously unrecognized biochemical partnership and... view more...

Study offers innovative profile of enzyme that aids tumor growth
To date, understanding the roles of uncharacterized enzymes in cell physiology and pathology has remained problematic. view more (2006-10-23)
DNA repair mechanisms relocate in response to stress
Like doctors making house calls, some DNA repair enzymes can relocate to the part of the cell that needs their help, a collaborative team of scientists at Emory University School of Medicine has found. view more (2009-03-27)
Genetic double-agents unmasked
Babraham Institute and Cancer Research UK scientists have discovered that certain enzymes with a key activity in the immune system may be important in stem-cell development, but may also work against us by contributing to the occurrence of cancer. view more (2004-10-26)
Enzyme cocktail converts cellulosic materials, water into hydrogen fuel
Tomorrow's fuel-cell vehicles may be powered by enzymes that consume cellulose from woodchips or grass and exhale hydrogen. view more (2009-02-12)
New insights into how the oncogenic protein c-Myc regulates cell growth
New findings by Swedish and German scientists on the regulation of cellular growth are published in the March issue of Nature Cell Biology. view more (2005-02-20)
Newly found enzymes may play early role in cancer
Researchers have discovered two enzymes that, when combined, could be involved in the earliest stages of cancer. Manipulating these enzymes genetically might lead to targeted therapies aimed at slowing or preventing the onset of tumors. view more (2008-12-29)
Scientists identify specific enzymes that make meningitis hard to fight
Two enzymes in meningitis bacteria which prevent the body from successfully fighting off the disease, and make the infection extremely virulent, have been identified in new research published today. view more (2007-02-23)
Researchers pinpoint enzyme involved in arthritis onset
Researchers from Cardiff University have uncovered a molecular pathway that plays a pivotal role in the onset of arthritis. Their research, published this week in Arthritis Research & Therapy, could aid in the discovery of novel targets for arthritis drugs. The researchers found that inhibiting the enzyme PKR could prevent two processes... view more... (2003-11-06)
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)
New understanding of COX-1 and COX-2 enzymes could lead to revised classification of pain meds, Queen's study shows
COX-1 and COX-2 enzymes may be blocked by pain medications such as Advil and Vioxx in a more complex manner than was previously understood, a Queen's University study has found. view more (2006-05-30)
How Montezuma gets his revenge
Every year, about 500 million people worldwide are infected with the parasite that causes dysentery, a global medical burden that among infectious diseases is second only to malaria. view more (2008-06-16)
New method of oxidising terpenes holds exciting possibilities for perfumery, flavouring and pharmaceuticals
Researchers in Oxford University’s Department of Chemistry have devised a new method of selectively oxidising terpenes to produce compounds of particular interest to the perfumery, flavour and pharmaceutical industries. view more (2002-08-02)
Record-breaking tuning lasers lead to better data flow
A novel two-chip approach for fabricating tunable lasers using a micro-machined mirror membrane was developed by IST project TUNVIC. Such lasers allow the free selection of a wavelength out of a wide range that will ultimately lead to an increase in flexibility of future optical networks. view more (2004-03-11)
