The endothelium interacts extensively with lipids and lipoproteins, but there are very few data regarding the ability of endothelial cells to secrete lipases. In this study, we investigated the ability of endothelial cells to secrete the triglyceride lipase and phospholipase activities characteristic of endothelial lipase (EL), a recently described member of the triglyceride lipase gene family....
a new system is presented for the generation ofrecombinant bacillus subtilis strains without antibioticmarkers. this system is based on two plasmids constructed in escherichia coli. the first plasmid phm30contains an incomplete hisi gene, the last gene in thehistidine biosynthesis operon of b. subtilis and part ofthe genes yvca and yvcb of unkown function flankinghisi at the 3´-end. the spectin...
Endothelial lipase (EL) is a new member of the triglyceride lipase gene family previously reported to have phospholipase activity. Using radiolabeled lipid substrates, we characterized the lipolytic activity of this enzyme in comparison to lipoprotein lipase (LPL) and hepatic lipase (HL) using conditioned medium from cells infected with recombinant adenoviruses encoding each of the enzymes. In ...
Streptomyces cinnamomeus Tü89 secretes a 30-kDa esterase and a 50-kDa lipase. The lipase-encoding gene, lipA, was cloned from genomic DNA into Streptomyces lividans TK23 with plasmid vector pIJ702. Two lipase-positive clones were identified; each recombinant plasmid had a 5.2-kb MboI insert that contained the complete lipA gene. The two plasmids differed in the orientation of the insert and the...
aquatic animals are important resources for extraction of valuable compounds such as enzymes. in this study, lipase was extracted from the intestine of rainbow trout. samples were defatted with acetone several times; ammonium sulphate (60%) was used for precipitation followed by ultrafiltration for concentrating the samples. the final purification of the enzyme was performed by passing of the s...
The tremendous mounting interest in lipase production is pertinent to the biotechnological applications that these enzymes offer. Lipase, belonging to the hydrolyze enzymes, is involved in copious biological functions including: hydrolysis insoluble triacylglycerol to mono and diacylglycerols and glycerol. Submerge fermentation technique was applied for the efficient production of this. Briefly...
Background and purpose: Pancreatic lipase is a major digestive enzyme in digestion and absorption of fats. Inhibition of the pancreatic lipase activity has always been one of the goals of researchers to control obesity and related disorders. Current inhibitory agents have several side effects. The aim of this study was to investigate the inhibitory effect of Ferula persica, Ginkgo biloba, Nel...
A gene encoding a thermotolerant lipase with broad pH was isolated from an Antarctic Pseudomonas strain AMS3. The recombinant lipase AMS3 was purified by single-step purification using affinity chromatography, yielding a purification fold of approximately 1.52 and a recovery of 50%. The molecular weight was approximately ∼60 kDa including the strep and affinity tags. Interestingly, the purified...
BACKGROUND The mammary gland is a conserved site of lipoprotein lipase expression across species and lipoprotein lipase attachment to the luminal surface of mammary gland vascular endothelial cells has been implicated in the direction of circulating triglycerides into milk synthesis during lactation. PRINCIPAL FINDINGS Here we report generation of transgenic mice harboring a human lipoprotein...
