Multifunctional protein that includes general (non sugar-specific) and sugar-specific components of the phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS). This major carbohydrate active transport system catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. The enzyme II FrwABC PTS system is involved in fructose transport. L-histidyl-[protein] + phosphoenolpyruvate = N(pros)-phospho-L-histidyl-[protein] + pyruvate D-fructose(out) + N(pros)-phospho-L-histidyl-[protein] = D-fructose 1-phosphate(in) + L-histidyl-[protein] The PTS EIIA type-2 domain is phosphorylated by phospho-HPr on a histidyl residue. Then, it transfers the phosphoryl group to the PTS EIIB type-2 domain. In contrast to classical PTS systems, the fructose-like PTS has no requirement for HPr and Enzyme I; PtsA combines a IIA domain with an Enzyme I and a HPr domains. Belongs to the PEP-utilizing enzyme family.
