The mechanism behind ice-forming bacteria

Researchers unlock mechanism of ice-nucleating bacteria

05-Nov-2024 - Particular „Ice-nucleating proteins“ produced by certain bacteria have the ability to control the freezing point of water – so efficiently that no other known material can compete. An interdisciplinary team led by Konrad Meister from the Max Planck Institute for Polymer Research has now uncovered ...

Researchers can measure distances in molecules optically

MINFLUX microscopy allows the determination of distances within biomolecules using an optical microscope

15-Oct-2024 - A team led by physicists Steffen Sahl and Stefan Hell at the Max Planck Institute for Multidisciplinary Sciences in Göttingen and the Max Planck Institute for Medical Research in Heidelberg has succeeded in measuring distances within biomolecules using a light microscope, down to one nanometer ...

Egg cell maintenance: Long-lived proteins may be essential

New findings on female fertility

11-Jul-2024 - Female mammals – including humans – are born with all of their egg cells. Of a woman’s one to two million egg cells, about 400 mature before menopause and can be fertilized. Some egg cells therefore survive for several decades – and need to remain functional over this long time. Extremely ...

Discovery of the first fractal molecule in nature

‘We stumbled on this structure completely by accident and almost couldn’t believe what we saw when we first took images of it using an electron microscope’

12-Apr-2024 - Snowflakes, fern leaves, romanesco cauliflower heads: many structures in nature have a certain regularity. Their individual parts resemble the shape of the whole structure. Such shapes, which repeat from the largest to the smallest, are called fractals. But regular fractals that match almost ...

From thousands of hours to a few minutes: Software Speeds Up Drug Development

Researchers develop novel method to predict the morphology of sugar coats on clinically relevant proteins within minutes

05-Mar-2024 - Sugars cover nearly all proteins present at the surface of the cells in our bodies, forming a shield around the proteins. Thus, these sugars influence how cells interact with their environment including pathogens, playing an important role in medical drug development. GlycoSHIELD, a new ...

Thianthrenium chemistry allows for reactivity switch of a nucleophilic amino acid into a versatile intermediate

Useful and broadly applicable tool in the field of chemical biology

03-Jan-2024 - Chemical diversification of proteins is an important concept in the study of biological processes and the complex structures of the proteins themselves. It involves using quick and mild reactions that selectively target a specific amino acid and therefore a building block of proteins. Cysteine is ...

New way to force pathogenic proteins into degradation

Researchers develop novel cancer protein killer and discover a new ligase for PROTACs

13-Dec-2023 - Most diseases are caused by proteins that have spun out of control. Unfortunately, so far, conventional drugs have been able to stop only a fraction of these troublemakers. A new class of drugs known as PROTACs holds great promise in pharmaceutical research. They mark proteins for targeted ...

Deciphering the secrets of spinal cord regeneration protein by protein

"With this understanding, we hope to develop new therapeutic approaches for spinal cord injury in humans in the future"

14-Nov-2023 - Scientists have long sought to understand how certain animals, such as zebrafish, are able to regrow nerve fibers and regain lost motor function after spinal cord injury. In humans, these injuries are irreparable and result in permanent loss of function, such as paralysis. An international team ...

Small protein, big impact

A small protein acts as a sensitive alarm for bacteria to be alert to antimicrobial peptides

16-Oct-2023 - Nature uses antimicrobial peptides as broad-spectrum antibiotics: They form the first line of defense against invading pathogens. Bacteria, in turn, have developed ways to circumvent these defenses. Microbiologists at the Max Planck Institute in Marburg have investigated how a small protein ...

New "radar" detects active cellular destroyers

Study provide an unprecedented look at the actors involved in the dynamic changes of our protein balance

04-Sep-2023 - Our cells have a fleet of 300 molecular machines, called cullin-RING ligases, or "CRLs" for short, that each is capable of triggering destruction of specific proteins for the well-being of our cells. However, most proteins are needed, therefore only those that block newly required cellular paths ...
