CC   -!- FUNCTION: Catalyzes both the uptake and excretion of putrescine. The
CC       uptake of putrescine is dependent on the membrane potential and the
CC       excretion involves putrescine-ornithine antiporter activity.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H(+)(in) + putrescine(in) = H(+)(out) + putrescine(out);
CC         Xref=Rhea:RHEA:28891, ChEBI:CHEBI:15378, ChEBI:CHEBI:326268;

CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=L-ornithine(out) + putrescine(in) = L-ornithine(in) +
CC         putrescine(out); Xref=Rhea:RHEA:28827, ChEBI:CHEBI:46911,

CC   -!- SIMILARITY: Belongs to the amino acid-polyamine-organocation (APC)
CC       superfamily. Basic amino acid/polyamine antiporter (APA) (TC 2.A.3.2)
CC       family.
