Lipoxygenases (LOX) play critical roles in mammalian biology in the generation of potent lipid mediators of the inflammatory response; consequently, they are targets for the development of isoform-specific inhibitors. The regio- and stereo-specificity of the oxygenation of polyunsaturated fatty acids by the enzymes is understood in terms of the chemistry, but structural observation of the enzyme-substrate interactions is lacking. Although several LOX crystal structures are available, heretofore the rapid oxygenation of bound substrate has precluded capture of the enzyme-substrate complex, leaving a gap between chemical and structural insights. In this report, we describe the 2.0 ? resolution structure of 8R-LOX in complex with arachidonic acid obtained under anaerobic conditions. Subtle rearrangements, primarily in the side chains of three amino acids, allow binding of arachidonic acid in a catalytically competent conformation. Accompanying experimental work supports a model in which both substrate tethering and cavity depth contribute to positioning the appropriate carbon at the catalytic machinery.

Mosses have substantial amounts of long chain C20 polyunsaturated fatty acids, such as arachidonic and eicosapentaenoic acid, in addition to the shorter chain C18 α-linolenic and linoleic acids, which are typical substrates of lipoxygenases in flowering p
Total synthesis of 12(R)-HETE, 12(S)-HETE, 2H2-12(R)-HETE and LTB4 from racemic glycidol via hydrolytic kinetic resolution
Rodríguez,Nomen,Spur,Godfroid,Lee
, p. 25 - 37 (2007/10/03)
The total synthesis of 12(R)-HETE, 12(S)-HETE (Samuelsson's HETE), [14,15-2H2]-12(R)-HETE and Leukotriene B4 from racemic glycidol is described. The key steps are the hydrolytic kinetic resolution of racemic TES-glycidol with salen-Co catalyst and the selective oxidation of primary silyl ethers, in the presence of secondary ones, under Swern conditions to give a short entry to both enantiomers of 12-HETE and LTB4.
