REMARK 3 AS BETA-MERCAPTOETHANOL FRAGMENT IS COMMON TO BOTH, A REMARK 3 DISULFIDE BRIDGE WITH BETA-MERCAPTOETHANOL WAS MODELLED REMARK 3 AT RESIDUES 22 AND 50 AND REFINED INTO DENSITY WITH A S-S REMARK 3 DISTANCE OF 2.08 A. ELECTRON DENSITY FOR THE CYS 22 REMARK 3 ADDUCT INDICATED TWO POSITIONS. THE MAJOR SITE (55% REMARK 3 OCCUPANCY) IS A RIGHT HANDED DISULFIDE, WITH CHI 3 = 85, REMARK 3 THE MINOR SITE (45% OCCUPANCY), IS A LEFT HANDED SPIRAL REMARK 3 DISULFIDE, CHI 3 = -79. A RIGHT HANDED DISULFIDE, REMARK 3 CHI 3 = 87 WAS BUILT INTO THE ELECTRON DENSITY AT CYS 50. REMARK 3 THESE MODELS WERE SUBSEQUENTLY REFINED USING RESTRAIN. REMARK 3 THE RESULTING CONFORMATIONS OF THE MIXED DISULFIDES WERE REMARK 3 CONFIRMED BY CALCULATING OMIT ELECTRON DENSITY MAPS.
