title: Cloning of a new cation ATPase from Plasmodium falciparum: conservation of critical amino acids involved in calcium binding in mammalian organellar Ca(2+)-ATPases.
abstract: In order to study molecules that may be involved in pH gradient formation in Plasmodium, we have identified a novel cation-translocating ATPase (P-type ATPase) gene from P. falciparum (Pf). We report the full-length nucleotide and deduced amino acid (aa) sequences of this gene that we called PfATPase4. The PfATPase4 protein shares features with the different members of eukaryotic P-type ATPases, such as a similar transmembrane (TM) organization and aa identity in functionally important regions. Interestingly, the PfATPase4 protein possesses conserved aa involved in calcium binding in mammalian organellar Ca(2+)-ATPases.
