7.6.2.7

ABC-type taurine transporter

ATP + H₂O + taurine-[taurine-binding protein]_{[side 1]} = ADP + phosphate + taurine_{[side 2]} + [taurine-binding protein]_{[side 1]}

tauABC (gene names), taurine ABC transporter, taurine-transporting ATPase

ATP phosphohydrolase (ABC-type, taurine-importing)

An ATP-binding cassette (ABC) type transporter, characterized by the presence of two similar ATP-binding domains/proteins and two integral membrane domains/proteins. Does not undergo phosphorylation during the transport process. A bacterial enzyme that interacts with an extracytoplasmic substrate binding protein and mediates the high affinity uptake of taurine. In Escherichia coli the enzyme imports a range of sulfonates (including taurine) that can be used as a source of sulfur.
