Details | THE ACTIVE FORM OF THE ENZYME IS THE WHOLE UNIT CELL CONTENT. IT CONSISTS OF 12 PROTOMERS. EACH PROTOMER IS MADE OF TWO POLYPEPTIDE CHAINS AND ONE FE(III). THE ASYMMETRIC UNIT CONSISTS OF 6 PROTOMERS. THEY ARE: CHAINS (A, M), CHAINS (B, N), CHAINS (C, O), CHAINS (D, P), CHAINS (E, Q), CHAINS (F, R). EACH PROTOMER CONTAINS AN ACTIVE SITE WITH FE(III) AS THE CENTER AND A VESTIGIAL SITE. THE ACTIVE SITES ARE NAMED: ACA, ACB, ACC, ACD, ACE, ACF. THE VESTIGIAL SITES ARE NAMED VEA, VEB, VEC, VED, VEE AND VEF. THE CHAIN IDENTIFIERS HAVE BEEN ASSIGNED AS FOLLOWS: ALPHA BETA WATERS A M G B N H C O I D P J E Q K F R L |

Refinement | Method to determine structure: NATIVE MODEL PHASES / Resolution: 2.19→6 Å / σ(F): 1 Details: APART FROM BINDING THE INHIBITOR AT THE ACTIVE SITE OF EACH PROTOMER, ONE MOLECULE OF THE INHIBITOR CORRESPONDING TO EACH PROTOMER ALSO BINDS AT THE LOCAL THREE-FOLD SYMMETRY. THE ...Details: APART FROM BINDING THE INHIBITOR AT THE ACTIVE SITE OF EACH PROTOMER, ONE MOLECULE OF THE INHIBITOR CORRESPONDING TO EACH PROTOMER ALSO BINDS AT THE LOCAL THREE-FOLD SYMMETRY. THE NONSTANDARD UNIT CELL I 2 WAS CHOSEN OVER THE EQUIVALENT C 2 CELL BECAUSE OF THE CONVENIENCE OF HAVING A BETA ANGLE NEAR 90 DEGREES AND TO MAINTAIN CONSISTENCY WITH THE INITIAL CRYSTALLIZATION REPORT. TO CONVERT FROM FRACTIONAL I 2 TO FRACTIONAL C 2, USE THE FOLLOWING TRANSFORMATION: [ 1.0 ][ 0.0 ][ 0.0 ] (XFRAC_I2) (XFRAC_C2) [ 0.0 ][ 1.0 ][ 0.0 ] X (YFRAC_I2) = (YFRAC_C2) [ -1.0 ][ 0.0 ][ 1.0 ] (ZFRAC_I2) (ZFRAC_C2) THE ORTHOGONAL COORDINATE SYSTEM CHOSEN FOR THIS ENTRY IS THAT DEFINED BY THE LOCAL SYMMETRY OF THE COMPLEX (23).
