THE COORDINATES FOR THE 25 MODELS WHICH WERE SUBMITTED TO SCIENCE REPRESENT THE BEST-FIT SUPERPOSITION OF THE BACKBONE C, CA AND N ATOMS OF HIV-1 NUCLEOCAPSID PROTEIN (FROM LYS 3 - GLU 51) AND ALL HEAVY ATOMS OF SL3 RNA RECOGNITION ELEMENT (FROM C 4 - G17). THE STRUCTURES WERE GENERATED WITH A TOTAL OF 719 EXPERIMENTAL DISTANCE RESTRAINTS WITH THE USE OF THE PROGRAM DYANA. HYDROGEN BOND RESTRAINTS WERE USED TO IMPROVE CONVERGENCE OF THE STRUCTURES, BUT NOT ALTER THE GLOBAL FOLD.
