1.1.2.8 ammonium - 742793 1.1.2.8 Butylamine - 742110 1.1.2.8 Dimethylamine - 742110 1.1.2.8 dipropylamine - 742110 1.1.2.8 ethanol does not affect the adhS gene expression but induces PQQ-ADH activity 725154 1.1.2.8 ethylamine inhibitory at high concentrations 742110 1.1.2.8 heptylamine - 742110 1.1.2.8 Hexylamine - 742110 1.1.2.8 Isobutylamine slight activation 742110 1.1.2.8 methylamine - 742110 1.1.2.8 methylamine methylamine is a 5fold better activator for enzyme ExaF in vitro than ammonium 742793 1.1.2.8 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 742110 1.1.2.8 octylamine - 742110 1.1.2.8 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 742110 1.1.2.8 Propylamine - 742110 1.1.2.8 triethylamine - 742110 1.1.2.8 trimethylamine - 742110 1.1.2.8 tripropylamine - 742110
