Hi,

I'm new to Pymol and am looking at the structure of pepsinogen (PDB: 3psg). This protein contains a 44 residue prodomain, which the pdb file says is assigned an insertion code 'P' and labelled 1 - 44. This prodomain is cleaved to yield pepsin (5pep), whose sequence is labelled 1 - 326. I gather Pymol should be able to see these as separate parts of the sequence, but it instead seems to interleave the sequences - I don't know if this affects the structure or not? Other programs (Chimera) show the sequence as it should be (P1-44...1-326).

Is there a way to have the sequence parts recognised in the sequence viewer? This would make it much easier for me to manipulate these sections. Please let me know if I haven't been clear.

Thanks,
Nick.
