Accepted name: ABC-type taurine transporter
Reaction: ATP + H2O + taurine-[taurine-binding protein][side 1] = ADP + phosphate + taurine[side 2] + [taurine-binding protein][side 1]
Other name(s): tauABC (gene names); taurine ABC transporter; taurine-transporting ATPase
Systematic name: ATP phosphohydrolase (ABC-type, taurine-importing)
Comments: 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.
