Ribosomes, the cellular machines that build proteins, are themselves made up of dozens of proteins and a few looping strands of RNA. A new study, reported in the journal Nature, offers new clues about how the ribosome, the master assembler of proteins, also assembles itself. "The ribosome has more than 50 different parts – it has the complexity of a sewing machine in terms of the number of parts," said University of Illinois physics professor Taekjip Ha, who led the research with U. of...

Berkeley Lab scientists reveal how protein-making machine bends without breaking It sounds like hype from a late-night infomercial: It can twist and bend without breaking! And wait, there's more: It could someday help you fend off disease! But in this case it's true, thanks to scientists from several institutions including the U.S. Department of Energy's Lawrence Berkeley National Laboratory. They derived atomic-scale resolution structures of the cell's protein-making machine, the ribosome,...

Researchers at the University of Illinois at Chicago have discovered a signaling mechanism in the bacterial ribosome that detects proteins that activate genes for antibiotic resistance. "The ribosome is one of the most complex molecular machines in the cell," said Alexander Mankin, UIC professor and director of the Center for Pharmaceutical Biotechnology. It is responsible for the production of all proteins in the cell, and in bacteria it is one of the major antibiotic targets. Understanding...

Even as research on the ribosome, one of the cell's most basic machines, is recognized with a Nobel Prize, scientists continue to achieve new insights on the way ribosomes work. Ribosomes are factories inside cells where messages coming from genes are decoded and new proteins pieced together on an assembly line. For the first time, scientists have a detailed picture of the ribosome trapped together with elongation factor G (EF-G), one of the enzymes that nudges the assembly line to move...

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...

 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...

A new, sharper picture of the nano-machine that translates our genetic program into proteins promises to help researchers explain how some types of antibiotics work and could lead to the design of better ones. The high-resolution snapshots of the bacterial ribosome were captured by scientists at the University of California, Berkeley, and Lawrence Berkeley National Laboratory (LBNL) with the lab's Advanced Light Source, which generates intense beams of X-rays that can reveal unprecedented...


Word of the Day
cruet
  • A vial or small glass bottle, especially one for holding vinegar, oil, etc.; a caster for liquids.
This word is Middle English in origin, and ultimately comes from the Old French, diminutive of 'crue,' flask.
