Researchers at Rensselaer Polytechnic Institute Discover New Method To Boost Enzymatic Activity Proteins are critically important to life and the human body. They are also among the most complex molecules in nature, and there is much we still don't know or understand about them. One key challenge is the stability of enzymes, a particular type of protein that speeds up, or catalyzes, chemical reactions. Taken out of their natural environment in the cell or body, enzymes can quickly lose their...

A new study reveals that a group of ancient enzymes adapted to substantial changes in ocean temperature and acidity during the last four billion years, providing evidence that life on Early Earth evolved from a much hotter, more acidic environment to the cooler, less acidic global environment that exists today.The study found that a group of ancient enzymes known as thioredoxin were chemically stable at temperatures up to 32 degrees Celsius (58 degrees Fahrenheit) higher than their modern...

Surprising new research shows that, contrary to conventional belief, remains of chitin-protein complex"”structural materials containing protein and polysaccharide"”are present in abundance in fossils of arthropods from the Paleozoic era. Previously the oldest molecular signature of chitin-protein complex was discovered in 25 million year old Cenozoic fossils and remnants of structural protein have also been discovered in 80 million-year-old Mesozoic fossils. Carnegie's George Cody...

A School of Science at Indiana University-Purdue University Indianapolis biophysicist has developed a new method to identify communication pathways connecting distant regions within proteins. With this tool, Andrew J. Rader, Ph.D., assistant professor of physics, has identified a mechanism for cooperative behavior within an entire molecule, a finding that suggests that in the future it may be possible to design drugs that target anywhere along the length of a molecule's communication pathway...

Researchers have determined the structure and mechanism of an enzyme that performs the crucial first step in the formation of cholesterol and a key virulence factor in staph bacteria. Chemists at the University of Illinois and collaborators in Taiwan studied a type of enzyme found in humans, plants, fungi, parasites, and many bacteria that begins the synthesis of triterpenes "“ one of the most abundant and most ancient classes of molecules. Triterpenes are precursors to steroids such as...

New insights from the nano world The mechanism for binding oxygen to metalloporphyrins is a vital process for oxygen-breathing organisms. Understanding how small gas molecules are chemically bound to the metal complex is also important in catalysis or the implementation of chemical sensors. When investigating these binding mechanisms, scientists use porphyrin rings with a central cobalt or iron atom. They coat a copper or silver support surface with these substances. An important...

New research at the University of North Carolina at Chapel Hill investigating the effect of temperature on extremely slow chemical reactions suggests that the time required for evolution on a warm earth is shorter than critics might expect. There has been controversy about whether life originated in a hot or cold environment, and about whether enough time has elapsed for life to have evolved to its present complexity. But new research at the University of North Carolina at Chapel Hill...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
