Remark 700 | SHEET THE SHEETS PRESENTED AS *SA1*, *SA2*, *SB1*, AND *SB2* ON SHEET RECORDS BELOW ARE ACTUALLY ...SHEET THE SHEETS PRESENTED AS *SA1*, *SA2*, *SB1*, AND *SB2* ON SHEET RECORDS BELOW ARE ACTUALLY EIGHT-STRANDED BETA-BARRELS. THESE ARE REPRESENTED AS NINE-STRANDED SHEETS IN WHICH THE FIRST AND LAST STRANDS OF EACH SHEET ARE IDENTICAL. THERE ARE SEVERAL BIFURCATED SHEETS IN THIS STRUCTURE. THESE ARE REPRESENTED BY TWO SHEETS WHICH HAVE ONE OR MORE IDENTICAL STRANDS. SHEETS *SA1* AND *SB1* REPRESENT ONE BIFURCATED SHEET. SHEETS *SA2* AND *SB2* REPRESENT ANOTHER BIFURCATED SHEET. |
