Surface protein editing in bacteria

University of Minnesota researchers have discovered this previously unknown signaling pathway that regulates surface proteins on bacteria that can lead to new targets for antibiotics.

X-rays reveal layout of loaded drug transporter

Experiments at DESY's X-ray source PETRA III have revealed the first structure of a biological transporter protein loaded with a pro-drug. Prodrugs are inactive medications that are metabolized into an active, functional ...

New life form answers question about evolution of cells

Bacteria and Archaea are two of the three domains of life. Both must have evolved from the putative last universal common ancestor (LUCA). One hypothesis is that this happened because the cell membrane in LUCA was an unstable ...

New tool for the crystallisation of proteins

ETH researchers have developed a new method of crystallising large membrane proteins in order to determine their structure. This will be of benefit to biological research and the pharmaceutical industry.
