Metabolite Identification
Common NameLeukotriene B4
DescriptionLeukotriene B4, also known as LTB4 or 5,12-dihete, belongs to the class of organic compounds known as leukotrienes. These are eicosanoids containing a hydroxyl group attached to the aliphatic chain of an arachidonic acid. Leukotrienes have four double bonds, three (and only three) of which are conjugated. Thus, leukotriene B4 is considered to be an eicosanoid lipid molecule. Leukotriene B4 is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.

Enzymes

General function:
Amino acid transport and metabolism
Specific function:
Epoxide hydrolase that catalyzes the final step in the biosynthesis of the proinflammatory mediator leukotriene B4. Has also aminopeptidase activity (By similarity).

General function:
Involved in G-protein coupled receptor protein signalin
Specific function:
Receptor for extracellular ATP > UTP and ADP. The activity of this receptor is mediated by G proteins which activate a phosphatidylinositol-calcium second messenger system. May be the cardiac P2Y receptor involved in the regulation of cardiac muscle contraction through modulation of L-type calcium currents. Is a receptor for leukotriene B4, a potent chemoattractant involved in inflammation and immune response (By similarity).
