Lingwood Lab discover new approach to rescue endogenous misfolded proteins

Newly made proteins which do not quite achieve the correct 3D shape in the ER are moved to the cell cytoplasm via a specific membrane pore, and broken down. Many disease causing gene mutations e.g. in cystic fibrosis, also result in misfolding of the mutant protein, and its transport though this pore, for cytoplasmic degradation. This pore is hijacked by some bacterial toxins which need to access the cytoplasm to […]

The roles of protein dynamics and water networks in catalysis visualized

The dimeric enzyme fluoroacetate dehalogenase is one of only a handful of protein catalysts that can break the strongest bond in organic chemistry, the one between carbon and fluorine atoms, in the process transforming the highly toxic pesticide fluoroacetate into glycolate, a benign molecule.  The laboratories of Emil Pai and Scott Prosser, together with the group of Régis Pomès and collaborators in the US and Japan, have […]

Proton pumping region of rotary ATPases revealed

In work led by postdoctoral fellow Mohammad T. Mazhab-Jafari, the Rubinstein laboratory used electron cryomicroscopy (cryo-EM) to determine the atomic structure of the membrane-bound region of a eukaryotic V-ATPase. This study, which was published in Nature, gives the first high-resolution structure for the membrane region of any rotary ATPase, a family of enzymes that includes proton pumping V-ATPases and proton-driven ATP synthases. The structure reveals several surprising features of […]
