TauBC
TauBC refers to a two-subunit membrane protein complex that forms part of the high-affinity taurine uptake system in many bacteria. In most organisms, TauB and TauC function as the transmembrane components of an ATP-binding cassette (ABC) transporter; they cooperate with a periplasmic binding protein TauA and an ATPase subunit to import taurine (2-aminoethanesulfonate) and related sulfonates from the periplasm into the cytoplasm.
TauB is predicted to consist of multiple transmembrane helices and contributes to the substrate translocation pathway;
Transport mechanism typically involves TauA binding taurine in the periplasm and delivering it to the TauBC
Genetics and regulation of TauBC are commonly linked to the tau gene cluster. TauABC components are often
Distribution and significance: the TauBC components are widely distributed among Gram-negative bacteria and play a key
