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 9-STRANDED BARREL THIS IS REPRESENTED BY A 10-STRANDED SHEET IN WHICH THE FIRST AND LAST STRANDS ARE IDENTICAL.
THE BIOLOGICAL UNIT CORRESPOND A MONOMER OF ASYMMETRIC UNIT. THE CRYSTALLOGRAFIC DIMER IS A CRYSTALLIZATION ARTIFACT MEDIATED BY A DISULFIDE BRIDGE OF CYS15 OF EACH MONOMER. THE SIZE EXCLUSION CHROMATOGRAPHY EXPERIMENTS DO NOT SHOW EVIDENCE OF A DIMER POPULATION.
RESIDUES 69 TO 83 (SEQUENCE: ITRSGAFTGEVSLQI) WERE SUBSTITUTED BY RESIDUES 76 TO 83 (SEQUENCE: GNADALAS)
