SHEET
THE TWO SHEETS PRESENTED AS *BAA* AND *BAB* ON SHEET
RECORDS BELOW ARE ACTUALLY EIGHT-STRANDED BETA-BARRELS.
EACH IS REPRESENTED BY A NINE-STRANDED SHEET IN WHICH THE
FIRST AND LAST STRANDS ARE IDENTICAL.

THIS IS MODEL(18) AS DESCRIBED IN THE JRNL RECORDS ABOVE. EACH OF THE TWO MONOMERS OF THE TETRAMER IN THE ASYMMETRIC UNIT HAVE ONE MG++, ONE AL+++, AND ONE D-XYLOSE/XYLULOSE BOUND AT PH 6.
