[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.
