This video shows you how to calculate the RMSD analysis of aa protein using the software VMD from the University of Illinois (http://www.ks.uiuc.edu/). VMD is a powerful tool for analysis of structures and trajectories. Numerous tools for analysis are available under the VMD Main menu item Extensions $ \rightarrow $ Analysis. In addition to these built-in tools, VMD users often use custom-written scripts to analyze desired properties of the simulated systems. VMD Tcl scripting capabilities are very extensive, and provide boundless opportunities for analysis. Example of a built-in analysis tool: the RMSD Trajectory Tool The built-in analysis tools in VMD are available under the menu item Extensions $ \rightarrow $ Analysis. These tools each features a GUI window that allow one to enter parameters and customize the quantities analyzed. In addition, all tools can be invoked in a scripting mode, using the TkConsole window. We will learn how to work with one of the most frequently used tools, the RMSD Trajectory Tool.
Paul Labute and Martin SantavyChemical Computing Group Inc.Introduction | Methodology | Results | Summary | References Introduction Active sites in proteins are usually hydrophobic pockets that involve sidechain atoms. It is non-trivial to quantify this rule of thumb. Methods such as [Goodford 1985] or [Miranker 1991] use interaction energies between the receptor and different probes in an […]
Nuclear receptors (NRs) are evolutionary conserved proteins that are expressed in the animal kingdom. The wide-ranging family of NRs contains more than 150 members that are represented by both steroidal and nonsteroidal receptors and by a multitude of orphan receptors, whose physiologically relevant ligands have not yet been identified. Many of these proteins act, in […]
