General annotation (Comments)

Function	Part of the ABC transporter complex ThiBPQ involved in thiamine import. Responsible for energy coupling to the transport system By similarity.
Subunit structure	The complex is composed of two ATP-binding proteins (ThiQ), two transmembrane proteins (ThiP) and a solute-binding protein (ThiB) Potential.
Subcellular location	Cell inner membrane; Peripheral membrane protein By similarity.
Sequence similarities	Belongs to the ABC transporter superfamily. Thiamine importer (TC 3.A.1.19.1) family. [View classification] Contains 1 ABC transporter domain.
