1	VAPOR DIFFUSION		293.15	SIRT3 (118-399) (10.3 mg/ml) was crystallized in complex with FDL (QPKKAC-7-amino-4-methylcoumarin) peptide (3 mM) and honokiol (1 mM) in 25% PEG 3350, 0.2 M Li2SO4 (or 0.2 M NaCl), and 0.1M HEPES, pH 7.5 as reservoir. Following formation of the ternary complex, crystals were soaked with carba-NAD (10 mM).
