Get PDB ID + Chain ID from Uniprot ID?

Question

I have a list of Uniprot IDs and need to know the PDB IDs plus the Chain IDs. With the code given on the Uniprot website I can get the PDB IDs but not the Chain Information.

import urllib.parse
import urllib.request

url = 'https://www.uniprot.org/uploadlists/'

params = {
'from': 'ACC+ID',
'to': 'PDB_ID',
'format': 'tab',
'query': UniProtIDs
}

data = urllib.parse.urlencode(params)
data = data.encode('utf-8')
req = urllib.request.Request(url, data)
with open('UniProt_PDB_IDs.txt', 'a') as f:
   with urllib.request.urlopen(req) as q:
      response = q.read()
      f.write(response.decode('utf-8'))

so this code gets me this:

From    To
A0A075B6N1  5HHM
A0A075B6N1  5HHO
A0A075B6N1  5NQK
A0A075B6T6  1AO7
A0A075B6T6  4ZDH

for the Protein A0A075B6N1 with PDB ID 5HHM the Chains are E and J so i need a way to also retrieve the chains to get something like that:

A0A075B6N1  5HHM_E 
A0A075B6N1  5HHM_J
A0A075B6N1  5HHo_E
A0A075B6N1  5NQK_B

It doesen't has to be in this format, later I convert it into a dictionary with the UniProt IDs as keys and the PDB IDs as values.

Thank you for your help in advance!
