Main Structural Targets for Engineering Lipase Substrate Specificity
Microbial lipases represent one of the most important groups of biotechnological biocatalysts. However, the high-level production of lipases requires an understanding of the molecular mechanisms of gene expression, folding, and secretion processes ...

Drosophila Lipase 3 Mediates the Metabolic Response to Starvation and Aging
The human LIPA gene encodes for the enzyme lysosomal acid lipase, which hydrolyzes cholesteryl ester and triacylglycerol. Lysosomal acid lipase deficiency results in Wolman disease and cholesteryl ester storage disease.

Lipase catalysis in organic solvents: advantages and applications
Lipases are industrial biocatalysts, which are involved in several novel reactions, occurring in aqueous medium as well as non-aqueous medium. Furthermore, they are well-known for their remarkable ability to carry out a wide variety of chemo-, regio- and

6-O-glucose palmitate synthesis with lipase: Investigation of some key parameters [PDF]
Fatty acid sugar esters represent an important class of non-ionic bio-based surfactants. They can be synthesized from vinyl fatty acids and sugars with enzyme as a catalyst. Herein, the influence of the solvent, the lipase and the temperature on a model reaction between vinyl palmitate and glucose via enzymatic catalysis has been investigated and the ...

Superfluous amylase/lipase testing at a tertiary care hospital: a retrospective study
BACKGROUND: Measuring both serum amylase and lipase in the setting of acute pancreatitis is not recommended and monitoring changes in amylase and lipase levels after diagnostic results is of little added value.

Correctly validating results from single molecule data: the case of stretched exponential decay in the catalytic activity of single lipase B molecules [PDF]
The question of how to validate and interpret correctly the waiting time probability density functions (WT-PDFs) from single molecule data is addressed. It is shown by simulation that when a stretched exponential WT-PDF, with a stretched exponent alfa and a time scale parameter tau, generates the off periods of a two-state trajectory, a reliable ...
