SHEET DETERMINATION METHOD: DSSP THE SHEETS PRESENTED AS "AB" IN EACH CHAIN ON SHEET RECORDS BELOW ... SHEET DETERMINATION METHOD: DSSP THE SHEETS PRESENTED AS "AB" IN EACH CHAIN ON SHEET RECORDS BELOW IS ACTUALLY AN 8-STRANDED BARREL THIS IS REPRESENTED BY A 9-STRANDED SHEET IN WHICH THE FIRST AND LAST STRANDS ARE IDENTICAL.
MEMBER OF THE CELLULASE FAMILY OF GLYCOSYL HYDROLASES

OUR NUMBERING BEGIN AT THE FIRST RESIDUE OBTAINED AFTER CLEAVAGE OF THE PROSEQUENCE. ONLY THE CATALYTIC DOMAIN HAS CRYSTALLISED. THIS CORRESPOND TO RESIDUES 27 TO 329 IN THE DATABASE. THE FIRST 3 RESIDUES ARE NOT VISIBLE IN ELECTRON DENSITY. A THIRD CONFORMATION HAS BEEN BUILT FOR GLU 228. THE A CONFORMER IS THE ONE OBERVED IN THE MICKAELIS FORM.THE B AND C CONFORMERS ARE PART OF THE COVALENT INTERMEDIATE FORM. TYR 202 SOULD ALSO BE IN 3 CONFORMATIONS TO AVOID CLASHES WITH GLU 228 BUT IT COULD NOT BE BUILT DUE TO DISORDER
