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 ...

The enzyme with the iron heart

Results could lead to new biocatalysts for sustainable biotechnology

11-Dec-2023 - Nitrogenases are the only enzymes capable of reducing atmospheric nitrogen to bioavailable nitrogen (ammonia), a process essential for all life on Earth. Using cryogenic electron microscopy, researchers at the Max Planck Institute for Terrestrial Microbiology in Marburg, Germany, have now solved ...

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 ...
