Rerefinement of SLV in 50 mM NaCl. Top: Original NMR ensemble (left, models 1–10 from pdb 1TBK) and minimized average structures from the rerefined NMR ensemble (right). Loop resides U₆₉₆ to U₇₀₀ in color. Bottom: U-turn loop residues in the original ensemble (left) and after rerefinement (right). Each ensemble is RMS fit on all heavy atoms. Three of the rerefined average minimized structures deviate from the rest of the ensemble and are highlighted green.
