New interaction mechanism of proteins discovered

Researchers have discovered a previously unknown way in which proteins interact with one another and cells organize themselves. This new mechanism involves two fully unstructured proteins forming an ultra-high-affinity complex due to their opposite net charge. Proteins usually bind one another as a result of perfectly matching shapes in their three-dimensional structures. Source: Feed4

Film Memento helped uncover how the brain remembers and interprets events from clues

In the Christopher Nolan film Memento (2000) the protagonist suffers from long-term memory loss and is unable to retain new memories for no longer than a few minutes. The events unfold in reversed chronological order. The results deepen our understanding of how the brain functions, how narratives work in film, and memory mechanisms impaired by […]

Bacteria produce more substances than hitherto assumed

The bacterium Streptomyces chartreusis is an antibiotic-producing bacterium that releases more metabolites into the surrounding medium than scientists assumed based on the analysis of the genome. Many of the substances are likely released to mediate interactions with its environment. They might also include molecules that are of interest as potential pharmaceutical agents. A research team […]
