General annotation (Comments)

Function	The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active -transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. This system is involved in lichenan transport.
Catalytic activity	Protein EIIB N(pi)-phospho-L-histidine/cysteine + sugar = protein EIIB + sugar phosphate.
Subcellular location	Cytoplasm Potential.
Induction	Induced by lichenan, lichenan hydrolysate and cellobiose. Subject to carbon catabolite repression.
Domain	The EIIB domain is phosphorylated by phospho-EIIA on a cysteinyl or histidyl residue, depending on the transported sugar. Then, it transfers the phosphoryl group to the sugar substrate concomitantly with the sugar uptake processed by the EIIC domain.
Sequence similarities	Contains 1 PTS EIIB type-3 domain.
