Details | THE STRUCTURE WAS DETERMINED USING TRIPLE-RESONANCE NMR SPECTROSCOPY AND AUTOMATED ANALYSIS OF 3D STRUCTURE. THE COORDINATES IN THIS ENTRY WERE GENERATED FROM SOLUTION NMR DATA. PROTEIN DATA BANK CONVENTIONS REQUIRE THAT CRYST1 AND SCALE RECORDS BE INCLUDED, BUT THE VALUES ON THESE RECORDS ARE MEANINGLESS. |
