Chimeras of Hepatic Lipase and Lipoprotein Lipase

Chimeric molecules between human lipoprotein lipase (LPL) and rat hepatic lipase (HL) were used to identify structural elements responsible for functional differences. Based on the close sequence homology with pancreatic lipase, both LPL and HL are believed to have a two-domain structure composed of an aminoterminal (NHz-terminal) domain containing the catalytic Ser-His-Asp triad and a smaller ...

Lipoprotein lipase, hepatic lipase, and carnitine in premature infants.

Twenty six preterm infants were studied at the age of 2, 7, and 26 days. The activities of lipoprotein and hepatic lipase in plasma taken 15 minutes after a heparin bolus of 100 IU/kg had been given and the concentrations of carnitine in serum and urine were measured. The mean gestational age was 31 weeks (range 26-35 weeks) and birth weight 1580 g (range 840-2280 g). Thirteen infants weighed u...

Hepatic lipase, lipoprotein metabolism, and atherogenesis.

The role of hepatic lipase as a multifunctional protein that modulates lipoprotein metabolism and atherosclerosis has been extensively documented over the last decade. Hepatic lipase functions as a lipolytic enzyme that hydrolyzes triglycerides and phospholipids present in circulating plasma lipoproteins. Hepatic lipase also serves as a ligand that facilitates lipoprotein uptake by cell surface...

Functional characterization of a chimeric lipase genetically engineered from human lipoprotein lipase and human hepatic lipase.

Lipoprotein lipase (LPL) and hepatic lipase (HL) mediate the hydrolysis of triglycerides and phospholipids present in circulating lipoprotein particles and are essential for normal lipid metabolism. Both enzymes have a similar primary amino acid structure and share requirements for intact catalytic, lipid binding, and heparin binding domains. However, LPL and HL exhibit different substrate spec...

Inheritance of high density lipoprotein and lipoprotein lipase and hepatic lipase activity.

The role of genetic and environmental factors in the regulation of plasma high density lipoprotein (HDL) was estimated in 17 monozygotic (MZ) and 18 dizygotic (DZ) male twins randomly selected from the Finnish Twin Cohort Study. In addition to HDL cholesterol, we determined the HDL subfractions, HDL2 and HDL3, and the major HDL apoproteins (apo) A-I and A-II. The activities of lipoprotein lipas...
