Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (Q9AJF5_THEVU | Q9AJF5)
molecular function
    GO:0005363    maltose transmembrane transporter activity    Enables 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.
biological process
    GO:0015768    maltose transport    The directed movement of maltose into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Maltose is the disaccharide 4-O-alpha-D-glucopyranosyl-D-glucopyranose, an intermediate in the catabolism of glycogen and starch.
