In order to do that, we will use a menu within the H-Bond Parameters panel: We will now display only specific H bonds for a residue of interest, and as an example it will be the hydroxyl of Serine 92. Click the Apply button at the bottom to reveal all H-bonds that can be displayed: within the helices, displayed side-chains and water molecules.Tools > Structure Analysis > FindHBond to find all hydrogen bonds in the structure using default parameters already selected.The first step is to find all hydrogen bonds with the defaults options.

In this exercise we will explore how to show hydrogen bonds and using selection methods to show them only for specific residues, in our example on the hydroxyl of Serine 92 ( SER 92.A OC.) The Publication menus alter the view prepared by the Interactive menu. Note: the Interactive menu options create a view. Publication 3 (depth-cued, rounded ribbon) Publication 1 (silhouette, rounded ribbon) Protein is wireframe, ligands are spheres The difference is that the ribbon is rainbow-colored from a blue-colored N-termial blue to a red-colored C-terminus.Įngage the Presets menus to explore the preset representations that are offered. The first one ** Presets > Interactive1(ribbon)** looks very similar to the current display when a molecule is opened. Bottom line, UCSF Chimera is a powerful application for molecular analysis that packs many useful features without feeling intimidating.Once you have found a suitable view, you can try the “ Presets” menus that alter the display of the molecule with preset options. The utility comes with a streamlined interface, a hefty documentation, tutorials and examples that can help you get started right away. You should also know that UCSF Chimera enables you to change the background, namely you can change the graphics window to a single color, a vertical gradient of multiple colors or even load an image from your computer. Without over complicating things, it should be mentioned that the tool comes with support for interactive shadows, morphing, Ramachandran plots and blast proteins. It also comes with a sequence viewer that actually makes it possible for you to find, view and edit sequence alignments. First off, you should know that it can generate high-quality images and animations. When it comes to features, the utility offers more than you would be tempted to believe upon first sight. Comes with an extensive set of visualization and analysis tools It also comes with a hefty documentation section that you should take a bit of time to read, as it may help you cut in half the learning period. Therefore, UCSF Chimera sacrifices a bit of practicality for the sake of offering a distraction-free environment for molecule analysis. Upon first launching the application, you are met by an almost too simple main window with nothing more than a visualization panel and a compact menubar, unlike other molecular analysis tools that usually go with extensive toolbars. Offers a set of useful features and a clear-cut interface
