Molecular modelers often face the challenge of managing and interacting with complex biological structures, where hundreds or even thousands of residues are involved. Navigating seamlessly between sequence-level data and 3D representations can greatly accelerate workflows, especially when structures need further refinement or visualization. This is where SAMSON’s Sequence View comes in.
The Sequence View in SAMSON provides an intuitive way to visualize and interact with the sequence information of biological systems. Its integration with the Document View and the 3D Viewport makes it an essential feature for anyone looking to gain a streamlined, cohesive modeling experience. Here’s how it works and why it’s a game-changer for molecular design:
What Is Sequence View?
Sequence View is an interactive tool in SAMSON that allows you to work on residues in a sequence while being directly synchronized with the 3D viewport. For instance, selecting residues in the Sequence View will automatically highlight them in the 3D Viewport and vice versa. Thanks to this interplay, you can switch between sequence and structural contexts depending on the task at hand without losing your focus.
Colorization Based on Biophysical Properties
One of the most powerful features of Sequence View is the ability to colorize residues directly from the sequence interface. You can assign colors based on various biophysical properties (e.g., hydrophobicity, charge) to better interpret patterns within the model. These colors are then transferred to the residues in the 3D viewport, providing an immediate visual correlation between sequence and structure.
Whether you’re studying interactions, understanding mutation impacts, or refining your structural models, this feature helps bring critical patterns to the forefront.
How to Access Sequence View
SAMSON has made accessing the Sequence View incredibly simple:
- Option 1: Select the View sequence command from the Home menu. This is one of the quickest ways to bring up the Sequence View for your structures.
- Option 2: Alternatively, you can right-click on the structure of interest and select Structural model > View sequence from the context menu.
Both approaches allow you to open the Sequence View and start analyzing your model instantly.
Working with Structures Containing Multiple Chains
If your model contains multiple chains, SAMSON intelligently prompts you to specify which chain(s) you want to examine in the Sequence View. As shown below, selecting the relevant chain (or multiple chains) ensures you’re working only on the intended areas at any given time:
Conclusion
SAMSON’s Sequence View is an indispensable tool for any molecular modeler seeking to enhance productivity and obtain better insights. By effortlessly linking sequence edits to their 3D structural counterparts, it simplifies complex workflows and opens new possibilities for investigations and design.
