Figure 2: SMase-C activity and unidentified esterase activity in TE and P30 fractions. Shadowed and clear bars correspond to specific activity of SMase-C or esterase activity from TE and P30 fractions from T. vaginalis trophozoites, respectively. The hydrolysis products were [14C]-phosphorylcholine for SMase-C activity and [14C]-choline for esterase activity. Each bar represents the mean ± SE from three independent experiments performed in triplicates.
