|---|---|
| Catalytic Activity | (6Z,8E,10E,14Z)-(5S,12R)-5,12-dihydroxyicosa- 6,8,10,14-tetraenoate + NADPH + O(2) = (6Z,8E,10E,14Z)-(5S,12R)- 5,12,20-trihydroxyicosa-6,8,10,14-tetraenoate + NADP(+) + H(2)O. |
| Cofactor | Name=heme; Xref=ChEBI:CHEBI:30413; Evidence= ; |
| Enzyme Regulation | Inhibited by carbon monoxide (CO). |
| Function | Cytochromes P450 are a group of heme-thiolate monooxygenases. This enzyme requires molecular oxygen and NADPH for the omega-hydroxylation of LTB4, a potent chemoattractant for polymorphonuclear leukocytes. {ECO:0000250|UniProtKB:Q08477, ECO:0000269|PubMed:16380383}. |
| Induction | Up-regulated in myeloid dendritic cells upon induction with LPS in vitro. Down-regulated upon migration of induced cells to the lymph node. |
| Pathway | Lipid metabolism; leukotriene B4 degradation. |
| Similarity | Belongs to the cytochrome P450 family. |
| Subcellular Location | Endoplasmic reticulum membrane {ECO:0000250}; Single-pass membrane protein . Microsome membrane ; Single-pass membrane protein . |
| Tissue Specificity | Highest level in polymorphonuclear leukocytes and dendritic cells. Detectable in lymph nodes, spleen, bone marrow and peripheral blood. Highly expressed in ovary. Very low level in liver, kidney, and smooth muscle. |
