Identifier

MALK

Protein name

RecName: Full=Maltose/maltodextrin import ATP-binding protein MalK; EC=3.6.3.19;

Gene name

malK

FUNCTION: Part of the ABC transporter complex MalEFGK involved in maltose/maltodextrin import. Responsible for energy coupling to the transport system (By similarity).

CATALYTIC ACTIVITY: ATP + H(2)O + maltose(Out) = ADP + phosphate + maltose(In).

SUBUNIT: The complex is composed of two ATP-binding proteins (MalK), two transmembrane proteins (MalG and MalK) and a solute-binding protein (MalE) (By similarity).

SUBCELLULAR LOCATION: Cell membrane; Peripheral membrane protein (By similarity).

SUBCELLULAR LOCATION: Cell inner membrane; Peripheral membrane protein (By similarity).

SIMILARITY: Belongs to the ABC transporter superfamily. Maltooligosaccharide importer (TC 3.A.1.1.1) family.
