1	VAPOR DIFFUSION, SITTING DROP	8.5	293	Holo protein at 10 mg/mL in 10 mM Tris-HCl pH 7, 100 mM NaCl and 2.5 mM 2-mercaptoethanol was mixed withf 1 mM compound 7b and 1 mM TCEP (final concentrations) and incubated on ice for 1 hr. Crystals of MshC in complex with compound 7b were grown in the Morpheus screen by dispensing droplets comprised of 300 nL protein mixture and 150 nL reservoir solution containing PEG550MME 20% (v/v), PEG20000 10% (w/v), Morpheus divalent 60 mM and Morpheus buffer system 3 pH 8.5.
