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.

B-factor Coloring

Atomic B-factor values are read from PDB and mmCIF input files and assigned as attributes that can be shown with coloring and used in atom specification. This example shows B-factor variation within a structure of the HIV-1 protease bound to an inhibitor (PDB 4hvp). For complete image setup, including positioning, color key, and label, see the command file bfactor.cxc.

Additional color key examples can be found in tutorials: Coloring by Electrostatic Potential, Coloring by Sequence Conservation
