Transmembrane subunit (TM) found in Periplasmic Binding Protein (PBP)-dependent ATP-Binding Cassette (ABC) transporters which generally bind type 2 PBPs. These types of transporters consist of a PBP, two TMs, and two cytoplasmic ABC ATPase subunits, and are mainly involved in importing solutes from the environment. The solute is captured by the PBP which delivers it to a gated translocation pathway formed by the two TMs. The two ABCs bind and hydrolyze ATP and drive the transport reaction. For these transporters the ABCs and TMs are on independent polypeptide chains. These systems transport a diverse range of substrates. Most are specific for a single substrate or a group of related substrates; however some transporters are more promiscuous, transporting structurally diverse substrates such as the histidine/lysine and arginine transporter in Enterobacteriaceae. In the latter case, this is achieved through binding different PBPs with different specificities to the TMs. For other promiscuous transporters such as the multiple-sugar transporter Msm of Streptococcus mutans, the PBP has a wide substrate specificity. These transporters include the maltose-maltodextrin, phosphate and sulfate transporters, among others.

NifC-like ABC-type porter; This model describes a clade of ABC porter genes with relatively weak homology compared to its neighbor clades, the molybdate (TIGR02141) and sulfate (TIGR00969) porters. Neighbor-Joining, PAM-distance phylogenetic trees support the separation of the clades in this way. Included in this group is a gene designated NifC in Clostridium pasturianum. It would be reasonable to presume that NifC acts as a molybdate porter since the most common form of nitrogenase is a molybdoenzyme. Several other sequences falling within the scope of this model are annotated as molybdate porters and one, from Halobacterium, is annotated as a sulfate porter. There is presently no experimental evidence to support annotations with this degree of specificity.

thiamine ABC transporter, permease protein; The model describes thiamine ABC transporter, permease protein in bacteria. The protein belongs to the larger ABC transport system. It consists of atleast three components: the inner mebrane permease; thiamine binding protein; an ATP-binding subunit. It has been experimentally demonstrated that the mutants in the various steps in the de novo synthesis of the thiamine and the biologically active form, namely thiamine pyrophosphate can be exogenously supplemented with thiamine, thiamine monophosphate (TMP) or thiamine pyrophosphate (TPP).
