Comments "This glucose level was chosen to ensure saturating conditions for glucose uptake (the Ks value for the glucose-specific phosphoenolpyruvate:- carbohydrate phosphotransferase system (PtsG) is known to be half-saturated at 3 to 10 µM, and that of the mannose- specific PtsM at 1.3 mM [primary sources])."
