distance geometry	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.	DYANA
