Remark 700 | SHEET DETERMINATION METHOD: DSSP THE SHEETS PRESENTED AS "AD" IN EACH CHAIN ON SHEET RECORDS BELOW ... SHEET DETERMINATION METHOD: DSSP THE SHEETS PRESENTED AS "AD" 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. THE SHEET STRUCTURE OF THIS MOLECULE IS BIFURCATED. IN ORDER TO REPRESENT THIS FEATURE IN THE SHEET RECORDS BELOW, TWO SHEETS ARE DEFINED. |
