Scientists decode black widow spider venom

Cryo-EM and MD simulations unveil the mechanism of the potent neurotoxin α-latrotoxin in forming calcium-permeable membrane pores

10-Oct-2024 - The black widow spider is one of the most feared spider species. Its venom is a cocktail of seven different toxins that attack the nervous system. These so-called latrotoxins specifically paralyse insects and crustaceans, but one of them, the α-latrotoxin, targets vertebrates and is also ...

A new drug target for psychiatric disorders

11-Sep-2024 - Misha Kudryashev’s lab at the Max Delbrück Center has identified a molecular intermediate of a serotonin receptor that is involved in diseases such as depression and schizophrenia. The study points to a potentially new target for therapeutics. A new study published in “The EMBO Journal” points ...

Cloud-based platform for analyzing cryo-EM data secures pre-seed investment

Dutch biotech start-up aims to accelerate the development of new active ingredients

04-Mar-2024 - CryoCloud, a biotech start-up based in Utrecht in the Netherlands, recently closed a financing round of 500,000 euros. The company has thus reached an important milestone on its way to optimizing cryo-electron microscopy (cryo-EM). CryoCloud was founded in 2021 by Munich-based Robert Englmeier, ...

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 ...

A close-up of biological nanomachines

Researchers take a deep look at peroxisomal processes

28-Sep-2023 - Every system has its waste disposal system. The cell organelles known as “peroxisomes” dispose toxic substances and fats in the human body, among other things, and, in doing so, they prevent serious illnesses. The “Pex” group of proteins (peroxisomes biogenesis factors) keep these “detox units” ...

Antibiotic ribosomal compounds deciphered

Combating multidrug-resistant bacteria through high-resolution structural imaging

10-Aug-2023 - A European research team led by the Department of Chemistry at the University of Hamburg presents structures of 17 different antibiotic ribosomal compounds with high detail resolution in a study. The knowledge could pave the way for the development of novel antibiotics to combat ...
