Understanding and analyzing complex molecular structures can be tricky, especially when trying to identify and interact with individual residues. For molecular modelers, one common challenge is ensuring smooth and precise control over residue selection while maintaining synchronization between the 2D sequence representation and the 3D structure. This is where the Sequence View in SAMSON can greatly simplify the workflow.
The Sequence View in SAMSON is seamlessly synchronized with the Document View and the 3D Viewport. When you select residues in one view, they automatically become selected in the other views, and vice versa. This means you can focus on detailed interactions, modify selections, or adjust colorizations across different representations without any hassle.
Streamlined Workflow for Residue Selection
Switching between a molecular viewer and sequence editor no longer needs to feel disjointed. With SAMSON’s Sequence View, residue selection syncs instantly, so you save time and avoid errors. For example, if a residue is selected in the Sequence View, it will highlight in the 3D Viewport as well, letting you visualize its spatial context immediately.
This synchronization is particularly useful for researchers working with large, complex structures where manually finding specific residues can be overwhelming. The Sequence View enables precise targeting and fine-grained interactions—perfect for tasks like inspecting active sites or visualizing mutation effects.
Enhanced Visualization with Residue Colorization
Beyond selection, the Sequence View also enables residue colorization based on biophysical properties. For instance, you can apply color schemes to highlight hydrophobic residues, charged residues, or any property relevant to your analysis. These colors are directly propagated to the 3D Viewport, creating an immediate connection between functional properties and the 3D molecular structure.
Colorization not only makes it easier to interpret molecular data but also facilitates effective communication when presenting or sharing insights with colleagues or collaborators. The visual clarity this feature offers can be a game-changer for researchers analyzing intricate systems like proteins, nucleic acids, or macromolecular assemblies.
Accessing the Sequence View
Accessing the Sequence View in SAMSON is quick and intuitive. You can choose either of the following methods:
- Click the View sequence command from the Home menu:

- Or, right-click on a structure in the 3D Viewport, then select Structural model > View sequence from the Context menu:

If you’re working with a large structure that contains multiple chains, a pop-up dialog allows you to specify which sequence(s) to display. This flexibility ensures that you can focus on exactly the parts of the structure you’re interested in:

Conclusion
SAMSON’s Sequence View provides molecular modelers with a powerful, intuitive way to simultaneously select, visualize, and colorize residues in both 2D and 3D representations. Simplify your workflows, enhance your analyses, and focus on what matters most: uncovering molecular insights.
