A characteristics difference between active transport systems in bacterial and animal cells is that the latter usually require sodium ions and operate by the process of co-transport. The melibiose permease system (TMG permease II) of Salmonella typhimurium has now been identified as a sodium-dependent co-transport system. Co-transport, and the analogous mechanism, counter-transport, may be the underlying mechanisms for the active transport of many solutes by bacterial cells, although they may be difficult to detect.
