Leishmania amazonensis inorganic phosphate transporter system is increased in the proliferative forms.

Here we characterize a high-affinity Pi transport system energized by a H+ gradient in Leishmania amazonensis. Pi uptake and transcription of LamPho84 gene are differentially regulated during parasite life cycle. Our data suggest that Pi acquisition could be a pivotal task for the success of the parasite throughout its life cycle.
