New bend on budding
JCB • VOLUME 170 • NUMBER 7 • 2005 1016 New bend on budding OPII vesicles form from the endoplasmic reticulum (ER). Now, Marcus Lee, Randy Schekman (University of California, Berkeley), and Lelio Orci (University of Geneva, Switzerland) find that insertion of the amphipathic helix of the Sar1 GTPase causes membrane deformation that initiates, and eventually ends, this vesicle formation process....

متن کاملThe Dependency of Nematic and Twist-bend Mesophase Formation on Bend Angle
We have prepared and studied a family of cyanobiphenyl dimers with varying linking groups with a view to exploring how molecular structure dictates the stability of the nematic and twist-bend nematic mesophases. Using molecular modelling and 1D 1H NOESY NMR spectroscopy, we determine the angle between the two aromatic core units for each dimer and find a strong dependency of the stability of bo...
متن کاملAccelerated Bend Minimization
We present an O(n) algorithm for minimizing the number of bends in an orthogonal drawing of a plane graph. It has been posed as a long standing open problem at Graph Drawing 2003, whether the bound of O(n7/4√logn) shown by Garg and Tamassia in 1996 could be improved. To answer this question, we show how to solve the uncapacitated min-cost flow problem on a planar bidirected graph with bounded c...
متن کاملBend into shape
Bacteria come in a variety of shapes, as most species elaborate on the ‘default’ sphere to resemble ovoids, rods, bend rods, spirals, branched filaments or other more complicated forms. How cells that are under considerable turgor pressure maintain a nonspherical shape is unclear, though it is known to depend on structural elements on either side of the cytoplasmic membrane: the murein (peptido...
