>TIGR00750 lao LAO/AO transport system ATPase; InterPro: IPR005129 Bacterial periplasmic transport systems require the function of a specific substrate-binding protein, located in the periplasm, and several cytoplasmic membrane transport components. In Escherichia coli K-12, the arginine-ornithine transport system requires an arginine-ornithine-binding protein and the lysine-arginine-ornithine (LAO) transport system includes a LAO-binding protein. Both periplasmic proteins can be phosphorylated by a single kinase, ArgK resulting in reduced levels of transport activity of the periplasmic transport systems that include each of the binding proteins. The ArgK protein acts as an ATPase enzyme and as a kinase..
