Sphingomyelinase Activity of Trichomonas vaginalis Extract and Subfractions
Figure 4
Dose dependence of membrane-associated SMase-C activity. Several protein total concentrations (0–400 μg) of P30 incubated for 150 min at pH 7.5 were tested. Then [14C]-phosphorylcholine released was measured. Symbols correspond to mean ± SE of nine determinations of three independent experiments.
