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 ...

Scientists have unraveled the step-by-step activation process of a protein with a deep evolutionary history in all domains of life, opening the door to harnessing its functions for use as a ...

All proteins are built from the same 20 amino acids. One of these, cysteine, was assumed not to have been present at the origin of life. In a new study, scientists have recreated how cysteine was ...

An international team of scientists have used advanced microscopy to image how ribosomes recruit to mRNA. Within a cell, DNA carries the genetic code for building proteins. To build proteins, the cell ...

In this new article publication from Acta Pharmaceutica Sinica B, authors Wei Shi, Wanzhen Li, Jianxin Zhang and colleagues from Shanghai Institute of Materia Medica Chinese Academy of Sciences, ...

In an important step during the early evolution of life on Earth, the formation of the amino acid cysteine delivered vital catalysts, which enabled the earliest protein molecules to form in water, ...
