NWO ENW Open Competition M1 Grant

In May 2024, Toon de Kroon was awarded an ENW-M1 grant to carry out the project “Regulation of membrane lipid acyl chain length: a tug of war between two enzymes?”. Optimal membrane fluidity is essential to ensure proper function of biological membranes. A key factor determining membrane fluidity is the length of the acyl chains attached to the lipids that constitute the membrane matrix. We aim to elucidate the regulation of lipid acyl chain length in the model eukaryote S. cerevisiae (baker’s yeast), including the players involved. The underlying hypothesis states that acyl chain length is determined by a tug of war between acetyl-CoA carboxylase and fatty acid synthase, the key enzymes catalyzing fatty acid synthesis.

Co-publication in Nature

Several group members of MBB have together with the group of Markus Weingarth, Kim Lewis from the US and others published in the August 11, 2022 issue of Nature. In this article the NMR structure of the complex of a rather novel antibiotic teixobactin in interaction with its target Lipid II is shown. Besides this, we demonstrate that it forms, together with Lipid II, fibrillar like structures on the membrane that are likely to be responsible for the additional membrane perturbation that teixobactin causes. Read the article Teixobactin kills bacteria by a two-pronged attack on the cell envelope.
Congratulations to Rhythm and all co-authors!
