Lipoxidase

 

an enzyme of the oxydoreductase class that oxidizes unsaturated fatty acids to peroxides.

Lipoxidase was first discovered in 1934 in soybeans. It was later found to exist in the seeds of other plants and in the muscle tissue of fish and mammals. The principal substrates for lipoxygenase are linoleic, linolenic, and arachidonic acids and their respective esters. Lipoxidase is activated by polypeptides.

While specific inhibition of COX-2 with celecoxib alone was sufficient to cause increased utilization of arachidonate by the lipoxygenase pathway, increases of LTB4 production were even greater in the presence of indomethacin, suggesting that the inhibition of both COX-1 and COX-2 provided more arachidonate substrate for metabolism by the lipoxygenase pathway.
