✦ Synopsis

Gram-negative bacteria are able to respond chemotactically to carbohydrates which are substrates of the bacterial phosphoeno1pyruvate:sugar phosphotransferase system (PTS). The mechanism of signal transduction in PTS-mediated chemotaxis is different from the well-studied mechanism involving methyl-accepting chemotaxis proteins (MCPs). In PTS-mediated chemotaxis, carbohydrate transport is required, and phosphorylation seems to be involved in both excitation and adaptation. In this review the roles of the components of the PTS in chemotactic signal transduction are discussed. o 1993 WiIey-Liss, Inc
