THE REFINEMENT STATISTICS PRESENTED FOR THIS ENTRY CORRESPONDS TO THE REFINEMENT CARRIED OUT USING THE TWINNING OPTION OF THE CNS PROGRAM. FOR THE DEPOSITION THE DIFFRACTION DATA WERE DETWINNED USING THE CNS PROGRAM. THEREFORE, SOME REFLECTIONS WERE LOST DUE TO THE DETWINNING PROCEDURE AND ARE MISSING IN THE DEPOSITED SF FILE, WHEREAS THE REFINEMENT STATISTICS CALCULATED BASED ON THE DETWINNED DATA MIGHT BE SLIGHTLY DIFFERENT FROM THOSE OBTAINED DURING THE "TWINNED" REFINEMENT INCLUDED IN THIS ENTRY.
