    Details THIS ENTRY CONTAINS SOLUTION NMR STRUCTURE OF A 39 RESIDUE SYNTHETIC PEPTIDE CONTAINING THE TWO ZINC BINDING DOMAINS FROM THE HIV-1 P7 NUCLEOCAPSID PROTEIN. THE TWO DOMAINS ARE COMPLETELY INDEPENDENT AND WERE SOLVED SEPARATELY. THE FIRST DOMAIN (CHAIN *N*, RESIDUES 1 - 17) WAS BASED ON 147 APPROXIMATE INTERPROTON DISTANCE RESTRAINTS. THE SECOND DOMAIN (CHAIN *C*, RESIDUES 22 - 39) WAS BASED ON 148 APPROXIMATE INTERPROTON DISTANCE RESTRAINTS. THE LINKER REGION IS HIGHLY FLEXIBLE AND CANNOT BE DEFINED FROM THE NMR DATA. THE METHOD USED TO DETERMINE THE STRUCTURES IS THE HYBRID METRIC MATRIX DISTANCE GEOMETRY-DYNAMICAL SIMULATED ANNEALING METHOD (NILGES, CLORE, AND GRONENBORN, FEBS LETT. 229, 317 (1988)). A TOTAL OF 15 SIMULATED ANNEALING STRUCTURES WAS CALCULATED FOR EACH DOMAIN. THE COORDINATES OF THE DOMAINS WERE THEN AVERAGED AND SUBJECTED TO RESTRAINED REGULARIZATION TO YIELD THE RESTRAINED MINIMIZED STRUCTURES. ONLY THESE COORDINATES ARE LISTED. THE FIRST CHAIN IS THE N-TERMINAL DOMAIN, AND THE SECOND IS THE C-TERMINAL DOMAIN. THE FIELD PRESENTED IN COLUMNS 61 - 66 IN THIS COORDINATE FILE REPRESENTS THE ATOMIC RMS DEVIATION OF THE INDIVIDUAL STRUCTURES ABOUT THE MEAN COORDINATE POSITIONS FOR EACH DOMAIN. THE COORDINATES OF THE TWO DOMAINS HAVE BEEN BEST FITTED TO EACH OTHER.
