Two proteins (Q9KXM8 and Q9KYD4) were 12 TMS proteins that proved to be members of the Drug:H+ Antiporter-3 (DHA3) Family within the Major Facilitator Superfamily (MFS). These 2 proteins were assigned TC numbers 2.A.1.21.18 and 2.A.1.21.19. A third protein proved to belong to the Cation Diffusion Facilitator (CDF) Family. This protein (Q9X897; 234 aas; 6 TMSs) was assigned to a new CDF Subfamily, TC# 2.A.4.8.1. A homologue (Q9RD35; 238 aas; 6 TMSs) was so similar to its paralogue, Q9X897 (83 % identity and 90% similarity with 1 gap), that

selleck products it was not entered into TCDB. A fifth protein (O86513; 334 aas; 9TMSs) proved to belong to the Drug Metabolite Exporter (DME) Family within the Drug Metabolite Transporter (DMT) Superfamily and was assigned TC# 2.A.7.3.43. A sixth protein (Q9KY69; 338 aas; 10 TMSs) was shown to belong to the Telurite-resistance/Dicarboxylate Transporter (TDT) Family and was assigned TC# 2.A.16.4.6. Finally, a seventh protein (Q9RJJ1; 429 aas; 12 TMSs) defined a new family within the Multi-drug Oligosaccharide-lipid/Polysaccharide (MOP) Flippase Superfamily, and this protein was assigned TC# 2.A.66.11.1. A single protein (Q9KYG0; 239 aas; 2 TMSs) was found that showed low sequence similarity with an auxilary transport protein found within TC category 8. It belongs to the Membrane-Periplasmic Auxilary-1 (MPA1) Protein with Cytoplasmic (C) Domain (MPA1-C or MPA1+ C) Family of complex carbohydrate exporters

[30, 31]. Proteins of this family function in conjunction with members of the Polysaccharide ADAMTS5 Transport (PST) Family (TC# 2.A.66.2) within the MOP Superfamily. It is not known if this auxiliary protein functions together with the MOP Superfamily homologue, 2.A.66.11.1. However, it was encoded by a gene that is adjacent to a glycosyl transferase and a polysaccharide deacetylase, suggesting a role in polysaccharide export. Q9KYG0 was assigned TC# 8.A.3.4.1. Five additional proteins were identified that are homologues of proteins currently CYC202 in vivo listed in TC Class 9 (putative transporters of unknown mechanism of action). The first of these, a YvaB homologue (Q9XA27; assigned TC# 9.A.31.1.2; 10 TMSs and 436 aas), is a distantly related member of the SdpC Peptide Antibiotic-like Killing Factor exporter (SdpAB) Family [32]. Members of this family had been previously identified only in species closely related to bacilli.
