Chemists in Mlheim devise a new way of optimizing enzymes for industrial applications Engineers are unlikely to tinker with the cooling system if they want to increase the size of an engine. Yet chemists at the Max Planck Institute for Coal Research have adopted an approach similar to this in their efforts to optimize an enzyme for practical applications. They substituted two amino acids at a site relatively distal to the biocatalyst's binding pocket, the location where the chemical reaction...

Structure will help MU researchers determine function, develop drugs to inhibit enzyme If subway terminals didn't exist and people had to exit subway stations to switch subway lines, transit time would increase. People also may encounter distractions, such as grabbing a cup of coffee, instead of getting on the other line. Molecules also use "terminals" to save transit time during enzyme-catalyzed processes. Using advanced X-radiation techniques, University of Missouri researchers were able to...

Researchers report that they have discovered "“ and now know how to exploit "“ an unusual chemical reaction mechanism that allows malaria parasites and many disease-causing bacteria to survive. The research team, from the University of Illinois, also has developed the first potent inhibitor of this chemical reaction. The findings appear in the Proceedings of the National Academy of Sciences. "There is an urgent need for new drugs to combat malaria and bacterial diseases such as...

A new study by a research team at Uppsala University shows how new functions can develop in an enzyme. This can explain, for example, how resistance to toxins can occur so simply. The findings are now being published in the Journal of Biological Chemistry. Every biological being needs a large number of enzymes for the many functions of cells. In the spirit of Darwin, enzymes in an organism can change over time to meet new needs. This is done by alterations in the enzymes' building blocks that...

Researchers at the Indiana University and Stanford University schools of medicine have determined how a "chemical chaperone" does its job in the body, which could lead to a new class of drugs to help reduce the muscle damage caused by heart attacks. Such drugs would work by restoring the activity of a mutated enzyme, rather than taking the more common approach of blocking the actions of a disease-related protein. The team, led by Thomas Hurley, Ph.D., associate chair and professor of...

A strip of paper infused with carbon nanotubes can quickly and inexpensively detect a toxin produced by algae in drinking water. Engineers at the University of Michigan led the development of the new biosensor. The paper strips perform 28 times faster than the complicated method most commonly used today to detect microcystin-LR, a chemical compound produced by cyanobacteria, or blue-green algae. Cyanobacteria is commonly found on nutrient-rich waters. Microcystin-LR (MC-LR), even in very...

Scientists at Washington University have isolated a channel that shuttles the vital but vulnerable heme molecule across biological membranes In some ways a cell in your body or an organelle in that cell is like an ancient walled town. Life inside either depends critically on the intelligence of the gatekeepers. If too many barbarians sneak into town, the town may be put to the torch. And if the cellular gatekeepers can't control the flow of ions and molecules into and out of the cell, the...
