How oxygen destroys the core of important enzymes

06-Nov-2019

New findings are expected to help protect the hydrogen-producing enzymes from harmful oxygen – which is interesting for biotechnological applications. Certain enzymes, such as hydrogen-producing hydrogenases, are unstable in the presence of oxygen. Researchers at Ruhr-Universität Bochum (RUB) ...

Dynamic images show rhomboid protease in action

01-Nov-2019

Rhomboid proteases are clinically relevant membrane proteins that play a key role in various diseases. Using solid-state NMR spectroscopy, researchers from Berlin’s Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP) have now been able to watch rhomboid proteases in a native lipid ...

New insights into the evolution of proteins

23-Oct-2019

How do bacteria manage to adapt to synthetic environmental toxins and, for example, to even develop strategies for using a pesticide and chemical warfare agent as food within less than 70 years? The evolutionary adaptations underlying such processes have now been studied in detail by an ...

The recipe for making a fruit fly

Scientists use mass spectrometry to determine the absolute copy number of nuclear proteins and histone marks

21-Oct-2019

Currently, most if not all of the proteins that are required for constructing a multicellular organism are known. However, it is largely unclear how many copies of each protein species are present and needed to permit an animal to develop into a complete organism. Researchers at the Max Planck ...

Chronobiology: Sleep and synaptic rhythms

15-Oct-2019

Chronobiologists at Ludwig-Maximilians-Universität (LMU) in Munich, Germany, show in two articles in the journal Science how critical the sleep-wake cycle is for protein and phosphorylation dynamics in synapses to ultimately regulate its activity. The internal clock controls virtually all ...

New method for quicker and simpler production of lipidated proteins

15-Oct-2019

Some of the body’s proteins are not just made up of amino acids, they are also ‘decorated’ with lipid chains, which significantly influence the biological functions of the protein. An example is the Ras protein, which plays a role in the development of many types of cancers and is only active and ...

New technology to streamline drug discovery

09-Oct-2019

George Mason University researchers have discovered the exact location where two proteins responsible for hiding cancer cells from the immune system bind. This discovery provides a novel approach to developing new cancer immunotherapy medicines that can be administered as a pill, compared to ...

Healthy organelles, healthy cells

02-Oct-2019

It has recently become clear just how important membraneless organelles are for cells. Now biochemists at ETH Zurich have discovered a novel mechanism that regulates the formation of these organelles. This has laid the foundation for more targeted research into diseases such as Alzheimer’s or ...

Spider silk: A malleable protein provides reinforcement

30-Sep-2019

Scientists from the University of Würzburg have discovered that spider silk contains an exceptional protein. It generates high bonding strength by making use of an amino acid scientists have hitherto paid little attention to. The finding could have important implications in many areas. Why are ...
