[PyMOL] Capping the ends of peptides

[Peter K. <pk...@se...>]

Dear All,

I made a tripeptide of the form gly-X-gly using the Build function. The 
amino end has a single hydrogen on the nitrogen, and the carboxyl end 
has only one oxygen so that additional amino acids could be added to 
it.  How do I make the amino end into an -NH3with a plus charge and the 
carboxyl end into a COO with a minus charge?

Thanks,
Peter
