简介
UCSF ChimeraX Cartoon Ribbon Rendering
- Ribbon Geometry: Cartoon ribbons pass through the exact α-carbon positions for helices and coils, but are smoothed by default for β-strands.
- Smoothing Mechanics: β-strand smoothing can be adjusted on a continuous scale from 0 (off) to 1.0 (fully on).
- Tethering: When sidechains are displayed, a tether is automatically drawn to connect them to the ribbon if they are detached; tether appearance is customizable.
- Granular Control: Smoothing adjustments can be applied globally or to specific residues.
- Command Syntax: The
cartooncommand (e.g.,cartoon :139,164 smooth 0) allows for precise, residue-specific control over ribbon smoothing without affecting the rest of the structure. - Example Case: Mandelate racemase (PDB 2mnr) is used as a reference to demonstrate the visual difference between smoothed and unsmoothed ribbon positions.
