RESIDUE NUMBERING FOLLOWS THE ORIGINAL DESCRIPTION OF CITATION 1, EXCEPT THAT FOR THE PURPOSES OF STRUCTURE CALCULATIONS, THE N-TERMINAL RESIDUE WAS TAKEN AS ASN8. THEREFORE, RESIDUES 30-36 IN THIS DEPOSITION CORRESPOND TO RESIDUES 1-7 IN CITATION 1 AND RELATED PDB ENTRY 1KAL. STRUCTURES WERE REFINED IN THE ABSENCE OF ANY ARTIFICIAL CONSTRAINTS DEFINING DISULFIDE BONDS UNTIL ALL NOES HAD BEEN ASSIGNED AND LOW TARGET FUNCTIONS WERE ACHIEVED (TF=0.6). 15 ADDITIONAL CALCULATIONS WERE PERFORMED WITH THESE INPUT DATA AND THE INCLUSION OF CONSTRAINTS DEFINING ALL POSSIBLE DISULFIDE PAIRING COMBINATIONS. THE STRUCTURES CONTAINING DISULFIDES BETWEEN [5(34)-13], [17-29] AND [22-27] DISPLAYED THE LOWEST TARGET FUNCTION (0.74, SECOND LOWEST WAS 1.54). ON THE BASIS OF THIS RESULT AND ANALYSIS OF NOES OBSERVED BETWEEN CYS SIDECHAIN PROTONS, THIS DISULFIDE BONDING ARRANGEMENT WAS ASSUMED TO BE CORRECT AND SERVED AS THE BASIS FOR THIS DEPOSITION. ; _pdbx_nmr_refine.software_ordinal 1 # loop_ _pdbx_nmr_software.classification _pdbx_nmr_software.name _pdbx_nmr_software.version _pdbx_nmr_software.authors _pdbx_nmr_software.ordinal refinement DYANA 1.5 'P.
