[Biopython] finding single domain proteins

[Charitha Fernando]

Hi guys,

I know this is not the appropriate forum to ask this question , I am really
sorry for doing so.
I am just begining to find my way through protein science--I have a question
I want a list of all Single domain proteins in the PDB, I am not sure if
there is a list like that?

I tried to play with both CATH/SCOP but I am not getting anywhere, is there
a list someone has of all the single domain proteins, does not matter if it
is all alpha or mixed, just need a list of them
Thanks,
Fernando
