The protein synthesis mechanism in the Giardia parasite

Cryo-electron microscopy was employed by Uppsala University researchers to reveal information on the protein synthesis mechanism in the parasite Giardia intestinalis, which causes diarrhea. The new findings could help in the development of specific medicines to combat Giardia and other protozoan parasites.

Researchers explore how tRNAs evolve in protein synthesis

In the process of protein synthesis, a peptide bond is formed between two amino acids that are bound to two different transfer RNAs (tRNAs). Researchers have long been perplexed as to how these tRNAs evolved to be so near to one another on the ribosome.

Viral RNA undergoes conformational changes to hijack host cells, says study

Scientists from the University of Colorado Anschutz Medical Campus recently identified how an RNA molecule from a virus develops a complex, three-dimensional structure, and is capable of changing its shape to hijack host proteins.

Researchers develop new approach to selectively turn on gene therapies in target cells

Researchers at MIT and Harvard University have designed a way to selectively turn on gene therapies in target cells, including human cells. Their technology can detect specific messenger RNA sequences in cells, and that detection then triggers production of a specific protein from a transgene, or artificial gene.
