Abstract

This work describes the application of NMR to the measurement of secondary deuterium (2° 2H) and carbon-13 (13C) kinetic isotope effects (KIEs) at positions 9− 13 within the substrate linoleic acid (LA) of soybean lipoxygenase-1. The KIEs have been measured using LA labeled with either protium (11, 11-h2-LA) or deuterium (11, 11-d2-LA) at the reactive C11 position, which has been previously shown to yield a primary deuterium isotope effect of ...
