Method	Details	Software
	THE STRUCTURE OF THE 15N/13C-LABELED HIRAN DOMAIN WAS DETERMINED IN THE PRESENCE OF UNLABELED SSDNA (DTTTTTTTTTT). THE DNA STRUCTURE WAS NOT DETERMINED. DNA-BINDING SITE WAS MAPPED USING NMR CHEMICAL SHIFT CHANGES. THE VALUES OF DNA-BINDING INDUCED CHEMICAL SHIFT CHANGES ARE AVAILABLE AS PART OF BMRB DEPOSITION 25492.	Sparky
