Human gastric lipase (HGL; triacylglycerol lipase; EC 3.1.1.3) plays an important role in the digestion of dietary triglycerides in the gastrointestinal tract, especially in patients suffering from pancreatic lipase deficiencies. The enzyme is secreted by the fundic mucosa of the stomach and hydrolyzes the ester bonds of triglycerides under acidic pH conditions, while cholesteryl esters are not...
We have determined the genotypes of two common polymorphisms in the lipoprotein lipase (S447X) and hepatic lipase (-480C/T) genes in a cohort of 285 representative selected Czech probands (131 male and 154 female), examined in 1988 and reinvestigated in 1996. The genotype distributions of both polymorphisms were in Hardy-Weinberg equilibrium and did not differ between male and female subjects. ...
To investigate the nutritional regulation of lipid metabolism in fish, molecular characterization of lipases was conducted in red sea bream Pagrus major, and the effects of fasting and refeeding on their gene expression was examined. Together with data from a previous study, a total of four lipase genes were identified and characterized as lipoprotein lipase (LPL), hepatic lipase (HL) and pancr...
AIMS To establish a relationship between lipase gene expression and aflatoxin production by cloning the lipA gene and studying its expression pattern in several aflatoxigenic and nontoxigenic isolates of Aspergillus flavus and A. parasiticus. METHODS AND RESULTS We have cloned a gene, lipA, that encodes a lipase involved in the breakdown of lipids from aflatoxin-producing A. flavus, A. parasi...
Candida antarctica lipase B (CALB) is one of the most widely used and studied enzymes in the world. In order to achieve the high-level expression of CALB in Pichia, we optimized the codons of CALB gene and α-factor by using a de novo design and synthesis strategy. Through comparative analysis of a series of recombinants with different expression components, we found that the methanol-inducible ...
A new system is presented for the generation of recombinant <span style="font-variant: normal; font-style: normal; font-family: Arial-ItalicMT; color: #231f20; font-size: 10pt...
Preliminary observations in a large-scale fermentation process suggested that the lipase expression of Pseudomonas alcaligenes can be switched on by the addition of certain medium components, such as soybean oil. In an attempt to elucidate the mechanism of induction of lipase expression, we have set up a search method for genes controlling lipase expression by use of a cosmid library containing...
The GDSL-lipase gene family is a very large subfamily within the supergene family of SGNH esterases, defined by the distinct GDSL amino acid motif and several highly conserved domains. Plants retain a large number of GDSL-lipases indicating that they have acquired important functions. Yet, in planta functions have been demonstrated for only a few GDSL-lipases from diverse species. Considering t...
Lipases have many applications in biotechnology, thanks to their ability of acylglycerides hydrolysis. They alsp possess the unique feature of acting at the lipid-water interface, which distinguishes them from esterases. Commercially useful lipases are produced by microorganisms with the extracellular lipase being produced by many bacteria including Pseudomonas. The greatest production of lipas...
