The N‐acetyl‐D‐mannosamine (ManNAc) transport system of Escherichia coli K92 was studied when this bacterium was grown in a chemically defined medium containing ManNAc as carbon source. Kinetic measurements were carried out in vivo at 37°C in 25 mM phosphate buffer, pH 7.5. Under these conditions, the uptake rate was linear for at least 15 min and the calculated K m for ManNAc was 280 μM. The transport system was strongly inhibited by sodium arsenate (97%), potassium cyanide (84%) and 2,4… Expand
