Protein
Putrescine transporter PotE
Organism
Haemophilus influenzae (strain ATCC 51907 / DSM 11121 / KW20 / Rd)
Function
Catalyzes both the uptake and excretion of putrescine. The uptake of putrescine is dependent on the membrane potential and the excretion involves putrescine-ornithine antiporter activity.
Similarity
Belongs to the amino acid-polyamine-organocation (APC) superfamily. Basic amino acid/polyamine antiporter (APA) (TC 2.A.3.2) family.
