Catalysis of the PEP-dependent, phosphoryl transfer-driven transport of substances across a membrane. The transport happens by catalysis of the reaction: protein N-phosphohistidine + lactose(out) = protein histidine + lactose phosphate(in). This differs from primary and secondary active transport in that the solute is modified during transport. Catalysis of the transfer of disaccharide from one side of the membrane to the other. Catalysis of the transfer of lactose from one side of the membrane to the other. Lactose is a disaccharide 4-O-beta-D-galactopyranosyl-D-glucose, and constitutes roughly 5% of the milk in almost all mammals. Catalysis of the transfer of a sugar from one side of the membrane to the other. A sugar is any member of a class of sweet, water-soluble, crystallizable carbohydrates, which are the monosaccharides and smaller oligosaccharides. Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: lactose(out) + H+(out) = lactose(in) + H+(in).
