Identify, engage, assassinate: How seahorse-like toxins kill insects

Researchers reveal the first-ever detailed structure of the bacterial toxin Mcf1: Useful for engineering novel biopesticides

02-Feb-2024 - Insect-killing bacteria typically release toxins to slay their hosts. The bacterium Photorhabdus luminescens, for example, pumps insect larvae full of the lethal ‘Makes caterpillars floppy 1’ (Mcf1) toxin, leading them to first become droopy and then dead. However, it has so far been a mystery ...

Fatty acid factory filmed at work

High-resolution images provide new insights into cellular fatty acid production: Potential for medicine and biotechnology

15-Nov-2023 - Fatty acids are essential in all living organisms: to store energy, form membranes, and multiply. They are produced by a complex cellular machinery – the fatty acid synthase (FAS). A team of the Max Planck Institute (MPI) for Multidisciplinary Sciences, led by Ashwin Chari and Holger Stark, have ...

Structure of key protein for cell division puzzles researchers

Researchers provide a first 3D snapshot of the CCAN protein complex and raise fundamental questions towards the creation of artificial chromosomes

17-May-2022 - Human cell division involves hundreds of proteins at its core. Knowing the 3D structure of these proteins is pivotal to understand how our genetic material is duplicated and passed through generations. The groups of Andrea Musacchio and Stefan Raunser at the Max Planck Institute of Molecular ...

World record resolution in cryo-electron microscopy

Novel technique visualizes individual atoms in a protein with cryo-electron microscopy for the first time

23-Oct-2020 - A crucial resolution barrier in cryo-electron microscopy has been broken. Holger Stark and his team at the Max Planck Institute (MPI) for Biophysical Chemistry have observed single atoms in a protein structure for the first time and taken the sharpest images ever with this method. Such ...

Why is Usain Bolt the fastest person on Earth?

Researchers observe muscles at work with the help of new microscopes

25-Jul-2016 - Twenty metres before the finish line Usain Bolt already opens his arms in triumph and ramps up his speed: even with his “handbrake” on, at 9.58 seconds, he runs the 100 metre stretch faster than anyone ever before in 2009 in Berlin. In the process, he reached a maximum speed of almost 45 ...
