General annotation (Comments)

Function

Involved in beta-(1-->2)glucan export. Its export to the periplasmic space is required to exert its action as a virulence factor. Transmembrane domains (TMD) form a pore in the inner membrane and the ATP-binding domain (NBD) is responsible for energy generation Probable. Ref.1

Catalytic activity

ATP + H2O + beta-glucan(In) = ADP + phosphate + beta-glucan(Out).

Subunit structure

Homodimer By similarity.

Subcellular location

Cell inner membrane; Multi-pass membrane protein Ref.1.

Domain

In NdvA the ATP-binding domain (NBD) and the transmembrane domain (TMD) are fused.

Sequence similarities

Belongs to the ABC transporter superfamily. Beta-(1-->2)glucan exporter (TC 3.A.1.108.1) family. [View classification]

Contains 1 ABC transmembrane type-1 domain.

Contains 1 ABC transporter domain.
