<p>I have a list of Protein ID such as Q9S9U6, A2XLL2, Q06402.
What name is this ID? UniProtKB ID?
And how can I get PDB ID from this list?
Is its PDB ID only one?</p>
<p>I'm using Python.</p>

I just wanna get an adjacency matrix from those IDs(Q9S9U6, A2XLL2, Q06402).

https://www.ebi.ac.uk/pdbe/docs/sifts/quick.html has the file you need for Uniprot <-> PDB

Not all proteins have knows structures, so it is expected that PDB IDs will not exist for all input UniProt IDs. Plus, some protein structures exist in multiple conformations, so there is no 1:1 mapping either.
