Remark 700 | SHEET SHEET 2 HAS A BETA BULGE AT RESIDUE SER A 207 AND SHEET 4 HAS A BETA BULGE AT RESIDUE GLY B ...SHEET SHEET 2 HAS A BETA BULGE AT RESIDUE SER A 207 AND SHEET 4 HAS A BETA BULGE AT RESIDUE GLY B 29. ADDITIONALLY, IN EACH OF SHEETS 2 AND 4, STRAND 4 CONTAINS AN EXTRA RESIDUE WHICH DISRUPTS THE HYDROGEN BONDING PATTERN. THIS IS REPRESENTED BY PRESENTING THE SHEETS TWICE (DESIGNATED SHEETS S2A, S2B AND S4A, S4B RESPECTIVELY) WHERE THE TWO REPRESENTATIONS DIFFER IN THEIR FIRST AND LAST STRANDS. |
