The essential translocase of the inner membrane (TIM) chaperones escort these proteins through the intermembrane space, but the structural and mechanistic details remain elusive. We have used an integrated structural biology approach to reveal the functional principle of TIM chaperones. Multiple clamp-like binding sites hold the mitochondrial membrane proteins in a translocation-competent elongated form, thus mimicking characteristics of co-translational membrane insertion. The bound preprotein undergoes conformational dynamics within the chaperone binding clefts, pointing to a multitude of dynamic local binding events. Mutations in these binding sites cause cell death or growth defects associated with impairment of carrier and β-barrel protein biogenesis. Our work reveals how a single mitochondrial “transfer-chaperone” system is able to guide α-helical and β-barrel membrane proteins in a “nascent chain-like” conformation through a ribosome-free compartment.}, author = {Weinhäupl, Katharina and Lindau, Caroline and Hessel, Audrey and Wang, Yong and Schütze, Conny and Jores, Tobias and Melchionda, Laura and Schönfisch, Birgit and Kalbacher, Hubert and Bersch, Beate and Rapaport, Doron and Brennich, Martha and Lindorff-Larsen, Kresten and Wiedemann, Nils and Schanda, Paul}, issn = {0092-8674}, journal = {Cell}, keywords = {General Biochemistry, Genetics and Molecular Biology}, number = {5}, pages = {1365--1379.e25}, publisher = {Elsevier}, title = {{Structural basis of membrane protein chaperoning through the mitochondrial intermembrane space}}, doi = {10.1016/j.cell.2018.10.039}, volume = {175}, year = {2018}, } @article{8439, abstract = {Lipopolysaccharides (LPS) are complex glycolipids forming the outside layer of Gram-negative bacteria.

Recently, the natural products cyclomarin, ecumicin, and lassomycin have been shown to efficiently kill Mycobacterium tuberculosis persisters. Their target is the N-terminal domain of the hexameric AAA+ ATPase ClpC1, which recognizes, unfolds, and translocates protein substrates, such as proteins containing phosphorylated arginine residues, to the ClpP1P2 protease for degradation. Surprisingly, these antibiotics do not inhibit ClpC1 ATPase activity, and how they cause cell death is still unclear. Here, using NMR and small-angle X-ray scattering, we demonstrate that arginine-phosphate binding to the ClpC1 N-terminal domain induces millisecond dynamics. We show that these dynamics are caused by conformational changes and do not result from unfolding or oligomerization of this domain. Cyclomarin binding to this domain specifically blocked these N-terminal dynamics. On the basis of these results, we propose a mechanism of action involving cyclomarin-induced restriction of ClpC1 dynamics, which modulates the chaperone enzymatic activity leading eventually to cell death.}, author = {Weinhäupl, Katharina and Brennich, Martha and Kazmaier, Uli and Lelievre, Joel and Ballell, Lluis and Goldberg, Alfred and Schanda, Paul and Fraga, Hugo}, issn = {0021-9258}, journal = {Journal of Biological Chemistry}, keywords = {Cell Biology, Biochemistry, Molecular Biology}, number = {22}, pages = {8379--8393}, publisher = {American Society for Biochemistry & Molecular Biology}, title = {{The antibiotic cyclomarin blocks arginine-phosphate–induced millisecond dynamics in the N-terminal domain of ClpC1 from Mycobacterium tuberculosis}}, doi = {10.1074/jbc.ra118.002251}, volume = {293}, year = {2018}, } @article{13374, abstract = {Confining molecules to volumes only slightly larger than the molecules themselves can profoundly alter their properties.

Mechano-stimulation of mitochondria – via encounter with motile intracellular pathogens, via external pressure applied by an atomic force microscope, or via cell migration across uneven microsurfaces – results in the recruitment of the mitochondrial fission machinery, and subsequent division. We propose that MFF, owing to affinity for narrow mitochondria, acts as a membrane-bound force sensor to recruit the fission machinery to mechanically strained sites.

In anaphase, p120 is enriched at the cleavage furrow where it binds MKLP1 to spatially control RhoA GTPase cycling.
