摘要：
We have isolated and sequenced a cDNA for human liver LTB(4) omega-hydroxylase. The cDNA encoded a protein of 520 amino acids with a molecular weight of 59,853 Da. The cDNA-deduced amino acid sequence showed 87.3% homology to that of human polymorphonuclear leukocytes (PMN) LTB(4) omega-hydroxylase (CYP4F3). Northern blot analysis revealed that the mRNA hybridized to the specific cDNA fragment is expressed in human liver, but not in human PMN. The microsomes from yeast cells transfected with the cDNA catalyzed the omega-hydroxylation of LTB(4) with a K-m of 44.8 mu M. These results clearly show that a new form of the CYP4F LTB(4) omega-hydroxylase exists in human liver.
