7.3.2.4 |
| Accepted name: |
ABC-type nitrate transporter |
| Reaction: |
ATP + H2O + nitrate-[nitrate-binding protein][side 1] = ADP + phosphate + nitrate[side 2] + [nitrate-binding protein][side 1] |
| Other name(s): |
nitrate-transporting ATPase (ambiguous) |
| Systematic name: |
ATP phosphohydrolase (ABC-type, nitrate-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. The enzyme, found in bacteria, interacts with an extracytoplasmic substrate binding protein and mediates the import of nitrate, nitrite, and cyanate. |
