I'm using enzyme design to redesign a enzyme, and encountering a tough problem for me.
In the catalytic site, there is a protonated ASP, and a .cst file need to be given to constraint -OH of ASP and ligand.
Although I find the parameters of protonation state of ASP (ASP_P1.params or ASP_P2.params file) in the installation directory(.../rosetta_database/chemical/residue_type_sets/fa_standard/residue_types/protonation_states),
the 3 letter abbreviation of protonated ASP is also ASP, so I don't know how to inform the rosetta to recognize the ASPH.
I think a simple setting could sovle the problem, but it puzzuled me for a long time.Can someone give me a solution for this?
Thanks in advance for your suggestions.
