Hard to tell which PDB it is, because people seem to really like looking at this lad: https://www.ncbi.nlm.nih.gov/ipg/1RI7_A. Well, probably 1RI7.
PDB-REDO says 3 peptides flipped. Indeed, some parts of the structure get vastly improved with remixing! I don't think they were same residues (PDB# 26, 56) though…
