title: [The pleiotropic function of the phosphoenolpyruvate-dependent phosphotransferase system in bacteria. Communication II].
abstract: The structure and function of regulators and anti-terminators is under discussion in gram-positive bacteria. The regulators of lichen and levan operons (LiR and LevR) as well as the implementation of both gram-positive and negative regulations of operons by them are in the focus of attention. Po-independent termination is regarded by the example of the regulatory activity for the utilization systems of glucose (GlcT) beta-glucosides (LicT), sucrose (low-efficiency system SacY-SacX) and of glycerin (GlcP). Changes in the functional activity of the above systems, which are dependent on a condition of anti-terminators (phosphorylated or dephosphorylated forms and an ability to demirelize etc.) are regarded from the viewpoint of a possibility of occurrence of catabolic repression.
