Activity profile PfM1AAP at low pH. Aminopeptidase activity of (A) recombinant PfM1AAP and (B) soluble extracts of P. falciparum malaria parasites in the acidic pH range of 5.0–5.5 (0.1 M sodium acetate buffer) compared with neutral pH 7.2 (PBS). The preparations were incubated in the buffers just prior to the addition of 10 μM substrates (H-Ala-NHMec, H-Leu-NHMec and H-Arg-NHMec).
