THE COMPLETE C- REMARK 3 TERMINUS IS VISIBLE. IT FORMS A SALT-BRIDGE WITH THE N-TERMINUS. REMARK 3 ARG 39 IS DISORDERED IN TWO CONFORMATIONS. IN ADDITION, IT IS REMARK 3 ADJACENT TO CYS 38 OF THE DISORDERED 14-38 DISULFIDE AND IS PART REMARK 3 OF A DISORDERED ARGININE CAGE. ALA 58 IS THE C-TERMINAL RESIDUE. REMARK 3 IT IMMEDIATELY FOLLOWS THE DISORDERED GLY 56 - GLY 57 DOUBLET. REMARK 3 THE CYS14-CYS38 DISULFIDE BRIDGE IS OBSERVED IN TWO DISTINCT REMARK 3 CHIRALITIES (60 % RIGHT-HANDED, 40 % LEFT-HANDED). THE MAIN REMARK 3 CHAIN OF THREE RESIDUES AND THE SIDE CHAINS OF 10 RESIDUES ARE REMARK 3 MODELED IN TWO CONFORMATIONS. EIGHT SULFATE ANIONS (TWO WITH TWO- REMARK 3 FOLD SYMMETRY) ARE PRESENT IN THE ASYMMETRIC UNIT. ONE OF THEM REMARK 3 SHARES A SITE WITH THREE WATER MOLECULES. TWO ETHYLENE GLYCOL REMARK 3 MOLECULES MODELED PER ONE PROTEIN MOLECULE. REFINEMENT CONCLUDED REMARK 3 USING ONE CYCLE OF BLOCKED FULL-MATRIX LEAST-SQUARES ALGORITHM.
