Building a Peptide Sequence From Hand

There are more than one method in PyMOL for building a peptide sequence from hand.

  • Simply hold down the alt (option on Mac) key and type in the one-letter code for the sequence.
  • Use the fab command
  • Use the Builder in "Protein" mode
  • You can write a script like the following which will build the amino acid sequence "DCAHWLGELVWCT".
for aa in "DCAHWLGELVWCT": cmd._alt(string.lower(aa))
