A) KEEPING MANUAL ASSIGNEMENTS B) REMARK 3 ALLOWING MANUAL ASSIGNEMENTS TO VARIATE C) ADDING EXTRA CSVALUES REMARK 3 FROM STATISTICAL TABLES. REMARK 3 IF THE N-TERMINUS DOMAIN IS ALIGNED IT LOOKS STRUCTURED AND THE C- REMARK 3 TERMINUS ROTATES. THE TWO ALIGNMENTS GIVE A SOMEHOW DIFFERENT REMARK 3 IMPRESSION ABOUT THE PROTEIN AND VERIFY THAT EACH DOMAIN IS REMARK 3 INDIVIDUALLY STRUCTURED. REMARK 3 THERE ARE TWO B-SHEETS ONE WITH 4 STRANDS AND ONE WITH TWO LONG REMARK 3 STRANDS. REMARK 3 THE 4 STRANDS MIGHT BELONG TO THE SAME SHEET OR THEY MAY BE TWO REMARK 3 TIMES TWO STRANDS OR A SMALL B-BARREL. REMARK 3 THEY BIND AND THEY ARE STABILIZED BY ZN.
