CoA
-
in absence of KCl, 0.1 mM CoA inhibits activity over 40% irrespective of the concentration of glycine. In presence of KCl, CoA inhibits activity only slightly, less than 10%. In presence of potassium phosphate the inhibition is reduced to less than 2%. 2.5 mM, almost complete inhibition of salt-free enzyme
