Modern eukaryotic cells have proteins that enable chromosome segregation during cell division, new discoveries shed light on their origin in simpler prokaryotic organisms. Modern nucleated (eukaryotic ...

Prokaryotic Argonaute proteins (pAgos) represent a diverse family of enzymes that play pivotal roles in the defence systems of bacteria and archaea. They function by utilising short guide nucleic ...

This study was led by Prof. Ming Li and Prof. Hua Xiang (Institute of Microbiology, Chinese Academy of Sciences). Early bioinformatic analyses revealed that, in haloarchaeal genomes, the ago genes are ...

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 ...

Prokaryotic cells, which include all bacteria and archaea, are ancient, and relatively simple compared to eukaryotic cells, which are found in fungi, plants, and animals. Scientists have long sought ...

As a means of identifying and determining protein structures, artificial intelligence (AI) keeps growing stronger. For example, it is no longer limited to the study of protein monomers. It is ...
