Piloting ribosomes past proline pairs

Certain proteins are known to require Translation Factor EF-P for their synthesis, and a new study enlarges the size of the set. As some of its members are involved in bacterial pathogenicity, the results are also of therapeutic ...

Researchers develop model of 'near-optimal' genetic code

Researchers have created a model that may explain the complexities of the origins of life. Their work, which appears in the Journal of the Royal Society Interface, offers new insights into how RNA signaling likely developed ...

Study offers insight into the origin of the genetic code

An analysis of enzymes that load amino acids onto transfer RNAs—an operation at the heart of protein translation—offers new insights into the evolutionary origins of the modern genetic code, researchers report. Their ...

How the bat beats the lifespan rule

From the elephant to the mayfly, biologists say there is a general rule about longevity: the bigger the animal, the longer it lives.

Fly study finds two new drivers of RNA editing

RNA editing gives organisms a way to adapt the instructions that their DNA provides for making proteins. Few people would have described RNA editing as a simple process, but a new paper in Nature Communications demonstrates ...

Streamlining a common survival strategy in marine microbes

(Phys.org) —Despite advances made in the fields of DNA sequencing and analysis, researchers have barely begun to scratch the tip of the iceberg in cataloging the planet's microbial diversity, mainly because only a minute ...

Study reveals key step in protein synthesis

Scientists at the University of California, Santa Cruz, have trapped the ribosome, a protein-building molecular machine essential to all life, in a key transitional state that has long eluded researchers. Now, for the first ...
