Ovine pancreatic lipase : purification and some properties.
Lipase has been isolated from sheep pancreas. The lipoprotein complex formed in pancreas homogenates by the enzyme and endogenous lipids is split by treatment with acetone. Lipase is further purified by ion-exchange chromatography and gel filtration. The molecular weight and the amino-acid composition of ovine lipase are very similar to that of the porcine and bovine enzymes. As previously found in bovine lipase, no carbohydrate is covalently bound to the polypeptide chain which has a N-terminal residue of lysine. The study of the catalytic properties of ovine pancreatic lipase indicates that the enzyme is fully activated by colipase from various species in the presence of conjugated bile salt micellar solutions.
