[ccp4bb] modelling C-terminal COOH in coot

2012-02-17 Thread Hubing Lou
Dear all, I have a structure solved by molecular replacement. The C-terminus at the end of the chain shows as CO, not COOH. How do I make it into COOH in COOT? I tried to place an O in the relevant position, but seems not working this way. Thanks, Hubing

There is a button for doing this - add OXT, which if I recall is hidden in the other modelling tools menu. Tony. Sent from my iPhone On 17 Feb 2012, at 10:26, Hubing Lou louhub...@gmail.com wrote: Dear all, I have a structure solved by molecular replacement. The C-terminus at the end
