ID 7.6.2.16 DE ABC-type putrescine transporter. AN putrescine ABC transporter. AN putrescine transporting ATPase. CA putrescine(out) + ATP + H2O = putrescine(in) + ADP + phosphate + H(+). CC -!- ATP-binding cassette (ABC) type transporter, characterized by the CC presence of two similar ATP-binding domains/proteins and two integral CC membrane domains/proteins. CC -!- The enzyme from the bacterium Escherichia coli interacts with an CC extracytoplasmic substrate binding protein and mediates the high CC affinity uptake of putrescine. CC -!- Differs in specificity from EC 7.6.2.11, ABC-type polyamine CC transporter. DR Q9H7F0, AT133_HUMAN; Q95JN5, AT133_MACFA; Q5XF89, AT133_MOUSE; DR P31134, POTG_ECOLI ; //
