IntEnz Enzyme Nomenclature


Accepted name:
ABC-type taurine transporter
Other names:
tauABC (gene names)
taurine ABC transporter
taurine-transporting ATPase
Systematic name:
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. Formerly EC
