SEGMENTS A1159-A1171, A1210-A1226, A1308-1334, A1387-A1395, A1512-A1516, A1534-A1541 ARE IN POOR DENSITY, AND THE CHAIN TRACE IN THOSE REGIONS IS APPROXIMATE. STEREOCHEMISTRY OF ZN A3000, A3001 COORDINATION IS POOR. DEPOSITED STRUCTURE FACTORS USED FOR REFINEMENT OF THIS ENTRY ARE FROM SOLVENT FLATTENED EM MAP EMD CODE 6337 AFTER PLACING THE DENSITY INTO A CELL WITH DIMESIONS 112.000, 143.000, 106.000 AND ANGLES 90.00,90.00,90.00. APPLY THE FOLLOWING TRANSFORMATION MATRIX TO THE COORDINATES IN ORDER TO PLACE THE MODEL INTO THE DENSITY CALCULATED FROM THE DEPOSITED STRUCTURE FACTORS: MODEL2SF 1 -0.492787 0.222962 -0.841098 139.886 MODEL2SF 1 -0.456450 -0.889187 0.031721 169.772 MODEL2SF 1 -0.740818 0.399552 0.539950 33.800
