1	VAPOR DIFFUSION, SITTING DROP	5.2		MUCONATE LACTONIZING ENZYME (MLE; 5-10 MG/ML) WAS DIALYZED AGAINST 0.2 MM MNCL2, 7 MM MERCAPTOETHANOL, 50 MM TRIS (PH 7), AND CIS, CIS-MUCONATE WAS ADDED TO A FINAL CONCENTRATION OF 0.2 MM. CRYSTALS WERE GROWN AT ROOM TEMPERATURE BY SITTING-DROP VAPOR DIFFUSION AGAINST A WELL SOLUTION OF 70 MM NACL, 70 MM SODIUM ACETATE (PH 5.2), 0.25% POLYETHYLENE GLYCOL (AVERAGE MOLECULAR WEIGHT 3350). DROPS CONTAINED EQUAL VOLUMES (10 MICRO L) OF WELL SOLUTION AND MLE., vapor diffusion - sitting drop
