Abstract

Acid phosphatase activity has been studied in the ameba Mayorella palestinensis. Optimum activity of the enzyme was found to be at a pH of 3.2. The enzyme is inhibited by fluoride ion, but is not sensitive to Mg⁺⁺. The activity was found to be correlated with age of culture. Two maxima have been obtained, one from cultures in the logarithmic phase, and the other during the period of maximal cell encystation. These results suggest that acid phosphatase play an important role in cell metabolism during growth and differentiation processes of this ameba.
