Biochemists uncover new rules of mitochondrial protein import

Graphical abstract. Credit: Cell (2025). DOI: 10.1016/j.cell.2025.07.021 Mitochondria are cellular organelles that play an important role in making ATP (adenosine triphosphate), the molecular fuel that powers most cellular functions. These organelles originated over a billion years ago when a primitive archaeal cell entered into a symbiotic relationship with an ancestral bacterium. Over time, mitochondria became

Researchers uncover key insights into cholesterol’s structure in cell membranes

Graphical abstract. Credit: The Journal of Physical Chemistry A (2024). DOI: 10.1021/acs.jpca.4c02860 A new study by Rice University researchers led by Jason Hafner could open new pathways for understanding how cholesterol influences cell membranes and their receptors, paving the way for future research on diseases linked to membrane organization. This research was published in the

AI tools help uncover enzyme mechanisms for lasso peptides

Credit: Nature Chemical Biology (2024). DOI: 10.1038/s41589-024-01727-w Lasso peptides are natural products made by bacteria. Their unusual lasso shape endows them with remarkable stability, protecting them from extreme conditions. In a new study, published in Nature Chemical Biology, researchers have constructed and tested models for how these peptides are made and demonstrated how this information
