Sphingomyelinase Activity of Trichomonas vaginalis Extract and Subfractions
Figure 5
Effect of pH on membrane-associated SMase-C activity. Fractions of P30 containing 400 μg of proteins total by assay were tested by several pH values (2–10). Then [14C]-phosphorylcholine released was measured. Symbols correspond to mean ± SE of nine determinations of three independent experiments.
