(1R,3aS,3bR,5aR,7R,9aS,9bS,11aR)-1-[(2R)-6-fluoro-5-oxohexan-2-yl]-9a,11a-dimethylhexadecahydro-1H-cyclopenta[a]phenanthren-7-yl hydrogen sulfate (non-preferred name)

Structural diversity of bile salt hydrolases reveals rationale for substrate selectivity

0.2 M Lithium Sulfate, 0.1 M CAPS:NaOH, pH 10.5, 2M Ammonium Sulfate. Crystals formed in a 2:1 ratio of protein:mother liquor. 2.5 uM protein was incubated with 50 uM inhibitor for 1h at 37oC. Mixture was washed 3x with buffer in a spin concentrator and then concentrated to 8 mg/mL final concentration.
