Cloning, Expression, and Purification of a GDSL-like Lipase/Acylhydrolase from a Native Lipase-Producing Bacterium, Lactobacillus fermentum
Background: Lipase enzymes are of great importance in various industries. Currently, extensive efforts have been focused on exploring new lipase producer microorganism as well as genetic and protein engineering of available lipases to improve their functional features. Methods: For screening lipase-producing lactobacilli, isolated strains were inoculated onto tributyrin agar plates. Molecular ...
متن کاملStructural basis of the chiral selectivity of Pseudomonas cepacia lipase.
To investigate the enantioselectivity of Pseudomonas cepacia lipase, inhibition studies were performed with Sc- and Rc-(Rp,Sp)-1,2-dialkylcarbamoylglycero-3-O-p-nitrophenyl alkylphosphonates of different alkyl chain lengths. P. cepacia lipase was most rapidly inactivated by Rc-(Rp,Sp)-1,2-dioctylcarbamoylglycero-3-O-p-nitrophenyl octylphosphonate (Rc-trioctyl) with an inactivation half-time of ...
متن کاملCovalent immobilization of Pseudomonas cepacia lipase on semiconducting materials
Lipase from Pseudomonas cepacia was covalently immobilized on crystalline silicon, porous silicon and silicon nitride surfaces. The various stages of immobilization were characterized using FTIR (Fourier transform infrared) spectroscopy. The surface topography of the enzyme immobilized surfaces was investigated using scanning electron microscopy (SEM). The quantity of the immobilized active enz...
متن کاملPseudomonas cepacia lipase--mediated transesterification reactions of hydrocinnamates.
Use of lipase from Pseudomonas cepacia in transesterifcation reactions of ethyl hydrocinnamate with different alcohols has been examined. Among the alcohols tested, viz., n-butanol, iso-amyl alcohol, benzyl alcohol, n-octanol and 1-phenylethanol, only n-butanol yielded the transesterified product. Among the solvents tested, viz., n-heptane, n-hexane, cyclohexane, toluene, diisopropylether and n...
متن کاملCloning of a mineral phosphate-solubilizing gene from Pseudomonas cepacia.
We have recently shown that the ability of some gram-negative bacteria to dissolve poorly soluble calcium phosphates (Mps+ phenotype) is the result of periplasmic oxidation of glucose to gluconic acid via the quinoprotein glucose dehydrogenase (GDH), a component of the direct oxidation pathway. Escherichia coli K-12 derivatives synthesize apo-GDH but not the cofactor pyrroloquinoline-quinone (P...
