    • 229 → Ala, which is located in a functionally unimportant region of the FG loop. Isolation and purification of the membrane fraction containing HR were performed according to (33). HR, solubilized in 5% (w/v) cholate, 4 M KCl, and 50 mM tris-HCl (pH 7.2), was applied to a phenyl-sepharose CL-4B column (Pharmacia), washed with 0.4% (w/v) cholate buffer, and eluted by changing to 1% (w/v) β-octyl-glucoside in the same buffer. HR was concentrated on 50-kD cutoff membrane filters (Amicon) and batchwise incorporated into a cubic lipidic phase as previously described (14). Optimal crystallization conditions were found at a final composition of 58 to 62% (w/w) 1-monooleoyl-rac-glycerol, 4 M KCl, HR (3.3 to 4.0 mg/ml), and 50 mM tris-HCl (pH 6.5 to 7.4) (22°C, dark). Small crystals of HR formed within 2 weeks and attained final sizes of 0.1 mm by 0.1 mm by 0.02 mm.
