THESE ARE REPRESENTED BY TWO SHEETS WHICH HAVE ONE OR MORE IDENTICAL STRANDS. SHEETS *N2A* AND *N2B* REPRESENT ONE BIFURCATED SHEET AND STRAND FOUR OF SHEET BN1 IS ALSO PART OF THIS SHEET. SHEETS *C2A* AND *C2B* REPRESENT ONE BIFURCATED SHEET AND STRAND FOUR OF SHEET BC1 IS ALSO PART OF THIS SHEET. THE RESIDUES LISTED IN REMARK 500, TORSION ANGLES OUTSIDE THE EXPECTED RAMACHANDRAN REGIONS, ARE IN WELL DEFINED GAMMA-TURNS AT POSITIONALLY HOMOLOGOUS SITES ON BOTH LOBES. THE PEPTIDE BOND IN REMARK 500 AND ITS POSITIONAL HOMOLOG ARE ALSO SUBSTANTIALLY NON-PLANAR IN LACTOFERRIN |
