EC Tree
IUBMB Comments
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, ABC-type polyamine transporter.
