Dear Sudipta, for me, what works best is the following: - centre on the cysteine you want to "mutate";
- Extensions -> Modelling -> Replace residue; - enter the appropriate code (for cysteine sulfenic acid is "CSX"). This way, the chain ID, numbering, etc, is all kept. HTH, best, Jose ######################################################################## To unsubscribe from the CCP4BB list, click the following link: https://www.jiscmail.ac.uk/cgi-bin/webadmin?SUBED1=CCP4BB&A=1
