CC -!- FUNCTION: Part of the ABC transporter complex PotFGHI involved in
CC putrescine uptake (PubMed:8416922, PubMed:23719730). Responsible for
CC energy coupling to the transport system (PubMed:23719730). Imports
CC putrescine for maintenance of the optimal concentration of polyamines
CC necessary for cell growth in the presence of glucose (PubMed:23719730).
CC {ECO:0000269|PubMed:23719730, ECO:0000269|PubMed:8416922}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O + putrescine(out) = ADP + H(+) + phosphate +
CC putrescine(in); Xref=Rhea:RHEA:29995, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:43474,
CC ChEBI:CHEBI:326268, ChEBI:CHEBI:456216; EC=7.6.2.16;
CC Evidence={ECO:0000269|PubMed:23719730};
CC -!- ACTIVITY REGULATION: Transport is feedback inhibited by intracellular
CC polyamines. {ECO:0000269|PubMed:23719730}.
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=0.57 uM for putrescine {ECO:0000269|PubMed:23719730};
CC Vmax=23.0 nmol/min/mg enzyme {ECO:0000269|PubMed:23719730};
CC -!- SUBUNIT: The complex is composed of two ATP-binding proteins (PotG),
CC two transmembrane proteins (PotH and PotI) and a solute-binding protein
CC (PotF). {ECO:0000269|PubMed:23719730, ECO:0000269|PubMed:8416922}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000305}; Peripheral
CC membrane protein {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the ABC transporter superfamily. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAA24410.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
