They were annealed by heating to 367K for 10 minutes and allowed to cool to room temperature. Crystals with oligonucleotide 5ov4 were grown at 290K with the D153K variant of T5Fen. The resulting T5FenD153K:5ov4 structure was determined from crystals grown in 0.2 M MgCl2, 0.1 M Bis-Tris buffer pH 5.5, 25% w/v PEG 3350. |
