THIS IS REPRESENTED BY A NINE-STRANDED SHEET IN WHICH THE FIRST AND LAST STRANDS ARE IDENTICAL. THE SHEET PRESENTED AS B1 ON SHEET RECORDS BELOW IS ACTUALLY AN EIGHT-STRANDED ALPHA/BETA-BARREL. THIS IS REPRESENTED BY A NINE-STRANDED SHEET IN WHICH THE FIRST AND LAST STRANDS ARE IDENTICAL. THE SHEET PRESENTED AS C1 ON SHEET RECORDS BELOW IS ACTUALLY AN EIGHT-STRANDED ALPHA/BETA-BARREL. THIS IS REPRESENTED BY A NINE-STRANDED SHEET IN WHICH THE FIRST AND LAST STRANDS ARE IDENTICAL. THE SHEET PRESENTED AS D1 ON SHEET RECORDS BELOW IS ACTUALLY AN EIGHT-STRANDED ALPHA/BETA-BARREL. THIS IS REPRESENTED BY A NINE-STRANDED SHEET IN WHICH THE FIRST AND LAST STRANDS ARE IDENTICAL. SHEETS A3A AND A3B ARE IDENTICAL EXCEPT FOR THE FIRST STRAND. THIS STRAND IS SPLIT INTO TWO DISTINCT AMINO ACID RUNS. THE BULGE OF 11 AMINO ACIDS (RESIDUES 282-292) INCLUDES A HYDROGEN-BONDED TURN (RESIDUES 286-292). SHEETS B3A AND B3B ARE IDENTICAL EXCEPT FOR THE FIRST STRAND. THIS STRAND IS SPLIT INTO TWO DISTINCT AMINO ACID RUNS. THE BULGE OF 11 AMINO ACIDS (RESIDUES 282-292) INCLUDES A HYDROGEN-BONDED TURN (RESIDUES 286-292). SHEETS C3A AND C3B ARE IDENTICAL EXCEPT FOR THE FIRST STRAND. THIS STRAND IS SPLIT INTO TWO DISTINCT AMINO ACID RUNS. THE BULGE OF 11 AMINO ACIDS (RESIDUES 282-292) INCLUDES A HYDROGEN-BONDED TURN (RESIDUES 286-292).
