ENZYME entry: EC 7.4.2.6

Accepted Name
ABC-type oligopeptide transporter.
Alternative Name(s)
Oligopeptide ABC transporter.
Oligopeptide permease.
Oligopeptide-transporting ATPase.
Reaction catalysed
ATP + H(2)O + oligopeptide-[oligopeptide-binding protein](Side 1) <=> ADP + phosphate + oligopeptide(Side 2) + [oligopeptide-binding protein](Side 1)
Comment(s)
  • 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 import of oligopeptides of varying nature.
  • The binding protein determines the specificity of the system.
  • Cf. EC 7.4.2.9.
  • Formerly EC 3.6.3.23.
