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. |
