Ontology: Molecular Function (GO:0005363)

Definition: 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.

Synonyms: maltose porter activity
