Palmitoylation is a widespread, reversible lipid modification that has been implicated in regulating a variety of cellular processes. Approximately one thousand proteins are annotated as being palmitoylated, and for some of these, including several oncog

artifacts through PPT, posters, cartoons and sitcoms in class. For example, in unit 4 Low-carbon Actions, students investigated the effect of greenhouse before class, they felt the urgency of addressing environmental problems, and stimulated the motivation to participate in Low-carbon Actions. In ...

Background Diesel fuel has a widespread use in engines that vary in size, speed, power output and application. This includes all forms of land and sea transportation, power genera- tion units and machinery for industrial use. The thermal ...
A major challenge in applying this technique to proteins will be obtaining the necessary signal-to-noise ratio in the XAS/XES spectra to discern changes in a single active-site sulfur atom that is involved in the reaction amid a background of multiple "bystander" sulfur atoms in Cys and Met...
even argued that the observed signals were due to instrumental artefacts caused by background luminescence, and not due to Raman scattering [83,84]. There appears to be still much potential for future discoveries of porphyrins and their metabolites and degradation products in dinosaurs and other ...
