Arachidonic acid is metabolized to leukotrienen A4 with 5,6-epoxide by 5-lipoxygenases, and the product is further transformed to leukotrienee B4 by leukotriene A hydrolase Ford-Hutchinson_AW et al.. Leukotriene B4 is metabolized to lose its bioactivities either by omega -oxidation Hammarstrom_S or by leukotriene B4 12-hydroxydehydrogenase Yokomizo_T et al..
Leukotriene B4 causes adhesion of leukocytes to endothelial cells, stimulates chemotaxis and chemokinesis of leukocytes Hammarstrom_S , and enhances superoxide anion production by human polymorphonuclear leukocytes Sumimoto_H et al.. Leukotriene B4 binds to a specific receptor with 7 transmembrane domains coupled to Gi/Go or Gq protein Yokomizo_T et al..
cDNA and genomic DNA of 5-lipoxygenase Funk_CD and cDNA for Leukotriene A hydrolase Funk_CD were cloned. cDNA for leukotriene B 12-hydroxydehydrogenase was cloned Yokomizo_T et al..
