For molecular modelers, managing complex structural models can be a challenging task, especially when working with intricate biomolecular sequences. Deep insights often require seamless mapping between a structure’s sequence, 3D Viewport, and color-coded data representations. This is where SAMSON’s Sequence View becomes a highly valuable tool.
What is the Sequence View?
The Sequence View in SAMSON offers an intuitive way to explore and interact with the sequence of a molecular structure. By aligning residue selections across the document and visualization tools, it ensures that what you see corresponds consistently between different views. Imagine selecting residues in the sequence and seeing the corresponding atoms highlighted in the 3D viewport in real-time—it’s clarity made simple.
Key Features of the Sequence View
Dynamic Colorization: One of the most beneficial features of Sequence View is its ability to apply color codes to residues based on biophysical properties. For instance, you might color residues according to hydrophobicity, charge, or other individual properties. Even better, these color codes are not isolated—they can be seamlessly transferred to the 3D viewport for visual clarity. Here’s how it could look:
Multiple Chain Management: If working with structures containing multiple chains, SAMSON’s Sequence View makes it easy to navigate and choose precisely which sequence chains to display. A convenient pop-up dialog lets you select specific chains, which is crucial for detailed analysis of large assemblies or multi-chain proteins.
Accessing the Sequence View
There are multiple ways to access the Sequence View for your structure:
- From the Home menu, you can locate and click on the View sequence command:
- Alternatively, you can bring it up via the context menu. Simply right-click on the structure and select Structural model > View sequence:
Solving User Pains
Molecular modelers often face practical difficulties when managing residues in complex structures. Rigid workflows, lack of visual clarity, and limited interactivity between sequence and structure can slow analyses down considerably. SAMSON’s Sequence View eases this process by:
- Providing synchronized selection between the sequence and 3D views, ensuring intuitive exploration.
- Enabling advanced colorization which aids in identifying patterns or regions of interest within the structure.
- Simplifying the visualization of multi-chain systems through its selective sequence viewer dialog.
