ENZYME entry: EC 7.6.2.16

Accepted Name
ABC-type putrescine transporter.
Alternative Name(s)
Putrescine ABC transporter.
Putrescine transporting ATPase.
Reaction catalysed
ATP + H(2)O + putrescine-[putrescine-binding protein](Side 1) <=> ADP + phosphate + putrescine(Side 2) + [putrescine-binding protein](Side 1)
Comment(s)
  • 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 from the bacterium Escherichia coli interacts with an extracytoplasmic substrate binding protein and mediates the high affinity uptake of putrescine.
  • Differs in specificity from EC 7.6.2.11, ABC-type polyamine transporter.
