Catalysis of the transfer of disaccharide from one side of the membrane to the other. 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 + maltose(out) = protein histidine + maltose phosphate(in). This differs from primary and secondary active transport in that the solute is modified during transport. Catalysis of the transfer of maltose from one side of the membrane to the other. Maltose is the disaccharide 4-O-alpha-D-glucopyranosyl-D-glucopyranose, an intermediate in the enzymatic breakdown of glycogen and starch. This transporter is a porin so enables the energy independent passage of substances, sized less than 1000 Da, across a membrane. The transmembrane portions of porins consist exclusively of beta-strands which form a beta-barrel. They are found in the outer membranes of Gram-negative bacteria, mitochondria, plastids and possibly acid-fast Gram-positive bacteria. Catalysis of the transfer of maltose from one side of the membrane to the other. Maltose is the disaccharide 4-O-alpha-D-glucopyranosyl-D-glucopyranose, an intermediate in the enzymatic breakdown of glycogen and starch. Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: maltose(out) + H+(out) = maltose(in) + H+(in). Catalysis of the transfer of alpha-glucosides from one side of the membrane to the other. Alpha-glucosides are glycosides in which the sugar moiety is a glucose residue, and the anomeric carbon of the bond is in an alpha configuration. 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: ATP + H2O + maltose(out) = ADP + phosphate + maltose(in). Catalysis of the transfer of glucosides from one side of the membrane to the other. Glucosides are glycosides in which the sugar moiety is a glucose residue.
