2.3.1.192 | 5,5'-dithiobis(2-nitrobenzoate) |
phenylacetyl-CoA partially protects phenylacetyltransferase against 5,5'-dithiobis(2-nitrobenzoate) inactivation |

2.3.1.192 | CoA |
at physiologic concentrations of substrate, the arylacetyl transferase is extensively inhibited by CoA, inhibition is greatly reduced by ions. The 3-phosphate group on CoA is important for binding to the salt-free enzyme but in the presence of ions its importance is diminished |
|
2.3.1.192 | K2SO4 |
55 mM, 67% residual activity at physiological substrate concentration, 110% of initial activity at high substrate concentration |
