The broader command is simply “transparency” … it applies to not only surfaces, but also atomic representations, ribbons, etc. (whichever you specify) and there is a “frames” option for fading in/out over a specified number of frames. So for example with this ligand in 2gbp, the last command would fade it from the initial 0% to 100% transparent over 100 frames:
repr sphere :bgc
transp 100,a :bgc frames 100
… in this case “ligand” could be used instead of “:bgc” but I showed a more general case of specifying by residue name, since “ligand” doesn’t always get what you want. The “,a” means to affect atomic representations, not surfaces, ribbons, etc. See the manpage:
The “surftransparency” manpage (e.g. shown with command “help surftransparency” refers to this “transparency” command which essentially replaces it, although surftransparency still works too. See also the movie-related commands list, including “coordset” to play through your morph.
There is also a list of all commands, of course…
… and you can also use "Help… Search Documentation” in the menu to search for specific terms like “transparency"
I hope this helps,

I want to change it in the course of a morph between substrate-bound and substrate free forms of the same enzyme. I will probably have other questions, but this seems like a good place to start...
