Confers resistance to a diverse group of cationic or zwitterionic lipophilic compounds such as ethidium bromide, tetraphenylphosphonium, rhodamine, daunomycin, benzalkonium, rifampicin, tetracycline, puromycin, and to chemically unrelated, clinically important antibiotics such as chloramphenicol, erythromycin, and certain aminoglycosides and fluoroquinolones. Overexpression results in isopropyl-beta-D- thiogalactopyranoside (IPTG) exclusi [...] (410 aa) |
| | artJ | Arginine ABC transporter periplasmic binding protein; Part of the ABC transporter complex ArtPIQMJ involved in arginine transport. Binds L-arginine with high affinity. (243 aa) |
| | abgT | P-aminobenzoyl-glutamate transporter; Essential for aminobenzoyl-glutamate utilization. It catalyzes the concentration-dependent uptake of p-aminobenzoyl- glutamate (PABA-GLU) into the cell and allows accumulation of PABA-GLU to a concentration enabling AbgAB to catalyze cleavage into p- aminobenzoate and glutamate. It seems also to increase the sensitivity to low levels of aminobenzoyl-glutamate. May actually serve physiologically as a transporter for some other molecule, perhaps a dipeptide, and that it transports p-aminobenzoyl-glutamate as a secondary activity. The physiological ro [...] (508 aa) |
| | narK | Nitrate/nitrite transporter; Catalyzes nitrate uptake, nitrite uptake and nitrite export across the cytoplasmic membrane. Functions as a nitrate/nitrite exchanger, and protons are probably not co-transported with the substrate. (463 aa) |
| | chaA | Calcium/sodium:proton antiporter; Sodium exporter that functions mainly at alkaline pH. Can also function as a potassium/proton and calcium/proton antiporter at alkaline pH. Does not play a major role in calcium export. (366 aa) |
| | dauA | C4-dicarboxylic acid transporter; Responsible for the aerobic transport of succinate from the periplasm to the cytoplasm at acidic pH. Can transport other C4- dicarboxylic acids such as aspartate and fumarate. May also play a role in the regulation of C4-dicarboxylic acid metabolism at pH 7, via regulation of expression and/or activity of DctA. May act as a co- sensor of DcuS. (559 aa) |
| | cvrA | Putative cation/proton antiporter; K(+)/H(+) antiporter that extrudes potassium in exchange for external protons and maintains the internal concentration of potassium under toxic levels (By similarity). Participates in control of cell volume in low-osmolarity conditions; Belongs to the monovalent cation:proton antiporter 1 (CPA1) transporter (TC 2.A.36) family. NhaP2 subfamily. (578 aa) |
| | ssuA | Aliphatic sulfonate ABC transporter periplasmic binding protein; Part of a binding-protein-dependent transport system for aliphatic sulfonates. Putative binding protein; Belongs to the bacterial solute-binding protein SsuA/TauA family. (319 aa) |
| | ssuC | Aliphatic sulfonate ABC transporter permease; Part of a binding-protein-dependent transport system for aliphatic sulfonates. Probably responsible for the translocation of the substrate across the membrane; Belongs to the binding-protein-dependent transport system permease family. CysTW subfamily. (263 aa) |
| | ssuB | Aliphatic sulfonate ABC transporter ATPase; Part of the ABC transporter complex SsuABC involved in aliphatic sulfonates import. Responsible for energy coupling to the transport system (Probable). (255 aa) |
| | focA | Formate channel; Involved in the bidirectional transport of formate; Belongs to the FNT transporter (TC 2.A.44) family. (285 aa) |
| | cydD | Glutathione/cysteine ABC transporter export permease/ATPase; Somehow involved in the cytochrome D branch of aerobic respiration. Seems to be a component of a transport system. (588 aa) |
| | cydC | Glutathione/cysteine ABC transporter export permease/ATPase; Somehow involved in the cytochrome D branch of aerobic respiration. Seems to be a component of a transport system; Belongs to the ABC transporter superfamily. Cysteine exporter (TC 3.A.1.129.1) family. (573 aa) |
| | ybjE | Putative transporter; Mediates export of lysine; Belongs to the LysO family. (299 aa) |
| | artP | Arginine ABC transporter ATPase; Part of the ABC transporter complex ArtPIQMJ involved in arginine transport. Probably responsible for energy coupling to the transport system. (242 aa) |
| | artI | Arginine transporter subunit; Part of the ABC transporter complex ArtPIQMJ involved in arginine transport. (243 aa) |
| | artQ | Arginine ABC transporter permease; Part of the ABC transporter complex ArtPIQMJ involved in arginine transport. Probably responsible for the translocation of the substrate across the membrane. (238 aa) |
