ethanol
-
does not affect the adhS gene expression but induces PQQ-ADH activity
pentylamine
-
the alcohol oxidation activity of PpADH is strongly enhanced by pentylamine and the affinity for substrates is also improved by pentylamine as an activator, inhibitory at high concentrations
additional information
-
the enzyme requires ammonia or primary amines as activators in in vitro assays with artificial electron acceptors, the enzyme is activated by various primary amines, dimethylamine, and trimethylamine. tert-Butylamine is a poor activator. The hydrophobic interaction contributes to the binding of amine activators to the binding site in the enzyme

methylamine is a 5fold better activator for enzyme ExaF in vitro than ammonium
