Figure 5. Phenylacetate decarboxylase activity in the presence of potential inhibitors, including 2-phenylacetamide, 2-(4-hydroxyphenyl)acetamide, phenaceturic acid, and Atenolol.

For 2-(4-hydroxyphenyl)acetamide, inhibition of p-hydroxyphenylacetate decarboxylase activity is also shown (in blue). Activity is shown as relative to toluene production from phenylacetate in the absence of an inhibitor, except for the blue bar, which is relative to p-cresol production from p-hydroxyphenylacetate in the absence of an inhibitor. Error bars represent one standard deviation.
