Rhinoviruses have a sweet tooth
By Vincent Racaniello
Glucose metabolism. After transport into cells via glucose transporters (Gluts) and phosphorylation by hexokinase, glucose can enter glycolysis or the pentose phosphate pathway for nucleotide synthesis. Glycolysis produces 2 molecules of pyruvate from 1 of glucose, with a net energy yield of 2 ATP and 2 NADH. Image credit. Viral ...

TWiV 507: The fusion of form and function
By Vincent Racaniello
The TWiV team discuss the biology of Ebola viruses, and how localization of the membrane proteins of vaccinia virus drive function: the fusion machinery sits at the tips of virions, and binding proteins are at the sides. <span data-mce-type="bookmark" style="display: inline-block; width: 0px; overflow: hidden; line-height: 0;" class="mce_SELRES_start"></span><span data-mce-type="bookmark" style="display: inline-block; ...
Viral glycoproteins are not always randomly distributed
By Vincent Racaniello
The membranes of enveloped viruses contain embedded proteins that are essential for attaching to cell receptors and fusing with cell membranes. We generally view these glycoproteins as evenly distributed over the surface of the virus particle, as illustrated for influenza virus. But many more envelope glycoproteins are involved in attachment ...
TWiV 506: A Cafeteria full of jelly rolls
By Vincent Racaniello
The TWiVniks explain how the three-dimensional structure of the giant Cafeteria roenbergensis virus suggests a new mode of assembly, and the apparent elimination of dengue fever in an Australian city by release of mosquitoes harboring Wolbachia. <span data-mce-type="bookmark" style="display: inline-block; width: 0px; overflow: hidden; line-height: 0;" class="mce_SELRES_start"></span><span data-mce-type="bookmark" style="display: inline-block; width: ...
