REMARK 3 REMARK 3 REFINEMENT. REMARK 3 PROGRAM : X-PLOR REMARK 3 AUTHORS : BRUNGER REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: MOLECULAR MODELS WERE OBTAINED BY REMARK 3 DGII IMPLEMENTED IN INSIGHT II (BIOSYM INC., SAN DIEGO, CA), REMARK 3 FOLLOWED BY REFINEMENT WITH SIMULATED ANNEALING IN X-PLOR REMARK 3 (T.F.HAVEL, A.T.BRUNGER). RESIDUE 1 IN RESTRAINTS CORRESPONDS REMARK 3 TO RESIDUE 35 IN DSX. TWO ZINC BINDING SITES ARE: C44,C47,H59, REMARK 3 C63 AND H50,C68 C70, C73 EACH IN A TETRAHEDRAL PATTERN. (I.E., REMARK 3 10,13,25,29 AND 16,34,36,39 IN THE COORDINATES). RESIDUE 35-40 REMARK 3 AND 82-105 IN DEX ARE DISORDERED. STRUCTURES ARE GIVING FOR REMARK 3 RESIDUES 35 TO 86, CORRESPONDING TO 1 TO 52 NUMBERED IN THE REMARK 3 COORDINATES. NO MINOR CONFORMERS WERE DETECTED.
