title: Stereochemistry of 2-phenylethylamine oxidation catalyzed by bacterial copper amine oxidase.
abstract: The stereochemical course of the reaction catalyzed by a copper amine oxidase from Arthrobacter globiformis has been investigated using 2-phenylethylamine stereospecifically deuterium-labeled at the C1 position. Measurements of deuterium content in the product, phenylacetaldehyde, by gas chromatography-mass spectrometry revealed stereospecific abstraction of the pro-S hydrogen during the enzymatic oxidation, as predicted from the structure modeling for the enzyme-bound substrate.
