As Dave pointed out, you definitely need a TER card after the protein
chain, and before the first water moleule. Where did "receptor.pdb"
come from? I don't recall seeing this problem with a "real" PDB file
(e.g. from rcsb.org).
(Aside: note that the receptor.pdb file itself has no OXT atom, and
there is no change in chain ID on going from protein to waters. So all
the usual hints that one has reached a C-terminal residue are
missing....)
