7.6.2.7 |
| 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. |
