A series of structures of the eukaryotic protein-synthesis machinery are imaged at high resolution in defined states of the elongation phase of protein synthesis. Analysis suggests that there are ...

Proteins are essential biological molecules that perform a vast array of functions crucial for life, from catalyzing ...

Many viruses, including that perennial winter affliction, the influenza virus, are protected by a lipid membrane on loan from the host cell. The fusion proteins on the surface of the membrane are ...

Janelia researchers have uncovered a novel way that two of the structures inside cells-the endoplasmic reticulum (ER) and lysosomes-coordinate the production of proteins, highlighting how interactions ...

In prokaryotes such as bacteria, the initial mRNA produced after transcription is mature and fully functional to take part in the subsequent steps of protein synthesis. Therefore, the need for ...

A new study shows that eukaryotic ribosomes can be modified to respond to antibiotics in the same way that prokaryotic ribosomes do. According to researchers at the University of Illinois Chicago, the ...

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 ...

This is a preview. Log in through your library . Abstract An inverted membrane vesicle fraction isolated from uninfected Escherichia coli and largely derived from the inner membrane has been shown to ...
