Researchers at the University of California, Berkeley, have for the first time captured elusive nanoscale movements of ribosomes at work, shedding light on how these cellular factories take in genetic instructions and amino acids to churn out proteins.Ribosomes, which number in the millions in a single human cell, have long been considered the "black boxes" in molecular biology. "We know what goes in and what comes out of ribosomes, but we're only beginning to learn about what is going on in...

Researchers report this week that they have found a surprising but reliable marker of colony collapse disorder, a baffling malady that in 2007-2008 killed off more than a third of commercial honey bees in the U.S.Their study, in the Proceedings of the National Academy of Sciences, is the first to identify a single, objective molecular marker of the disorder, and to propose a data-driven hypothesis to explain the mysterious disappearance of American honey bees. The team included researchers...

Study questions current dogma Case Western Reserve University School of Medicine assistant professor in the Center for RNA Molecular Biology, Jeff Coller, Ph.D., and his team discovered that messenger RNA (mRNA) predominately degrade on ribosomes, fundamentally altering a common understanding of how gene expression is controlled within the cell. The study, "Co-translational mRNA decay in Saccharomyces cerevisiae", is published in the latest issue of Nature. "Many genetic diseases are linked...

As letters of the alphabet spell out words, when amino acids are linked to one another in a particular order they "spell out" proteins. But sometimes the cell machinery for building proteins in our bodies makes a mistake and the wrong amino acid is inserted. The consequences can be devastating, resulting in a garbled protein that no longer has the correct function, possibly leading to cancers and other diseases.Now scientists at The Scripps Research Institute have examined how an enzyme...

Selenium is a trace element crucial to life - too little or too much of it is fatal. In the July 17 issue of the journal Science, researchers at Yale University and University of Illinois at Chicago detail the molecular mechanisms that govern its metabolism in the human body. "It must require an intricately regulated uptake system," said Dieter Söll, co-senior author of the paper, Sterling Professor of Molecular Biophysics and Biochemistry at Yale. "There are 25 human selenoproteins, and...

Recycling is important not only on a global scale, but also at the cellular level, since key molecules tend to be available in limited numbers. This means a cell needs to have efficient recycling mechanisms. Researchers at the European Molecular Biology Laboratory (EMBL) and Heidelberg University, Germany, have now uncovered the first step in the recycling of a crucial molecular tag which ensures the instructions encoded in our genes are correctly carried out. The study, published this week...

According to a study in the Journal of Biological Chemistry, researchers have found the structure of a key genetic mechanism in bacteria, which may allow them to design a new type of antibiotic.Information stored in genes is translated into proteins, the workhorse molecules that make up the body's structure.  DNA (deoxyribonucleic acid) chains store instructions which are copied into mRNAs (messenger ribonucleic acids). The mRNAs are then transported to ribosomes that pair with transfer...

 In a new study, researchers at the University of Illinois have identified and visualized the signaling pathways in protein-RNA complexes that help set the genetic code in all organisms. The genetic code allows information stored in DNA to be translated into proteins.The researchers report their findings in a paper accepted for publication in the Proceedings of the National Academy of Sciences, and posted on the journal's Web site."Using molecular dynamics simulations and new...
