An enantiomeric pair of C2-chiral bifunctionalised spin labels having a pyrrolidine nitroxide moiety, whose configurations were determined by X-ray crystal diffraction analysis, was prepared and applied to troponin C whose binding mode of double disulfide linkage was proved by EPR spectroscopy.

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.
