1	VAPOR DIFFUSION, HANGING DROP	7.5	298	mtBioA was dialysed against fresh PLP (50 uM), desalted (25 mM HEPES pH 7.5, 50 mM NaCl) and concentrated to 10 mg/mL. Wells consisted of 100 mM HEPES pH 7.5, 100 mM MgCl2, and 5 mM small molecule ligand, and rows 1-6 of the plate contained a range of 9-14% w/v PEG 8000
