title: Molecular cloning of sheep lung dipeptidase: a glycosyl phosphatidylinositol-anchored ectoenzyme that converts leukotriene D4 to leukotriene E4.
abstract: Sheep lung dipeptidase was released from a plasma membrane preparation by digestion with a phosphatidylinositol-specific phospholipase C. The dipeptidase was purified to homogeneity using affinity chromatography followed by high performance liquid chromatography. The NH2-terminal sequence was determined and employed to prepare a probe to clone the c-DNA of the enzyme. The primary structure of sheep lung dipeptidase, deduced from the c-DNA exhibited a high homology to kidney dipeptidases cloned from other animal species. Northern analysis detected the m-RNA of the dipeptidase in lung, kidney, and intestinal tissues of the sheep.
