THE LAST STRAND IS INTERRUPTED BY A BETA-BLOWOUT OF EIGHT RESIDUES, FOUR OF WHICH (162 - 165) FORM A BETA-TURN. THIS IS REPRESENTED BY PRESENTING THE SHEET TWICE WITH DIFFERENT LAST STRANDS. IN E. COLI DFR THIS STRAND IS CONTINUOUS. IN L. CASEI DFR A BETA BULGE IS PRESENT. RESIDUES 172 AND 175 PARTICIPATE IN BOTH TIGHT TURN 8 AND BETA STRANDS 7 AND 9. RESIDUES 115 AND 116 FORM A BETA-BULGE IN STRAND E. RESIDUES 110 AND 111 FORM A BETA-BULGE IN STRAND E. |
