SHEET DETERMINATION METHOD: DSSP THE SHEETS PRESENTED AS "AA" IN EACH CHAIN ON SHEET RECORDS BELOW ... SHEET DETERMINATION METHOD: DSSP THE SHEETS PRESENTED AS "AA" IN EACH CHAIN ON SHEET RECORDS BELOW IS ACTUALLY AN 35-STRANDED BARREL THIS IS REPRESENTED BY A 36-STRANDED SHEET IN WHICH THE FIRST AND LAST STRANDS ARE IDENTICAL. THE SHEETS PRESENTED AS "AC" IN EACH CHAIN ON SHEET RECORDS BELOW IS ACTUALLY AN 7-STRANDED BARREL THIS IS REPRESENTED BY A 8-STRANDED SHEET IN WHICH THE FIRST AND LAST STRANDS ARE IDENTICAL.
