Morphing Movie

Morphing between atomic structures can be calculated wih the morph command and played back in an animation. This movie shows morphing between two conformations of the FGFR1 kinase domain:

• inactive structure (PDB 3C4F, chain A)
• activated structure (PDB 3GQI, chain A) with phosphorylated tyrosines and bound ATP analog

The tyrosine side chains and ATP analog are color-coded by element: light blue carbon, red oxygen, blue nitrogen, and orange phosphorus.

Morphing and other setup was done with the command file kmorph-prep.cxc, followed by interactively positioning the structure and saving the view with the command view name p1 (generally a session would also be saved at this point), then running kmorph-play.cxc to add 2D labels and record the movie.

Photosynthetic Reaction Center

The photosynthetic reaction center from a purple sulfur bacterium is shown as a cartoon with “tube” helices and membrane boundaries from the OPM database (Orientations of Proteins in Membranes, entry 1eys). Blue and red balls represent the cytoplasmic and periplasmic sides of the bacterial inner membrane, respectively. The title and other text labels were added with the 2dlabels command and repositioned interactively with the move label mouse mode . ChimeraX session file: prc.cxs
