Positive regulator of the licABCH operon. The regulatory activity of LicR is modulated by phosphorylation and dephosphorylation of the various LicR domains. It becomes activated via phosphoryl group transfer from PEP, EI and HPr on the two conserved histidine residues in the PRD 2 domain, whereas phosphorylation of the EIIA-like domain on His-559 by the PTS EIIB component LicB inactivates LicR (By similarity). Belongs to the transcriptional antiterminator BglG family.
