1.1.1.360 acetone 20% (v/v), 40% loss of activity 333 1.1.1.360 ATP inhibition displays Michaelis-Menten kinetics in a noncompetitive mode with respect to the cofactor NADP+ 4 1.1.1.360 ethanol 20% (v/v), 20% loss of activity 69 1.1.1.360 methanol 20% (v/v), 30% loss of activity 83 1.1.1.360 additional information EDTA added at up to 10 mm causes no loss of activity. Pyruvate, phosphoenolpyruvate, 3-phosphoglycerate, 2-phosphoglycerate, phosphate and diphosphate do not affect the activity when added to the standard assay at 5 or 20 mm 2
