A Penicillium simplicissimum strain has been found to produce an inducible extracellular lipase. Triolein was the best inducer for the enzyme production with the highest activity being achieved after 48 h of incubation. The purified lipase showed a molecular weight of 56,000 by SDS-PAGE. The enzyme exhibited a high ratio of apolar amino acids. The lipase was stable in the pH range of 5-7 and at 50 degrees C for 15 min. The optimum assay conditions were 37 degrees C and pH 5.0. The enzyme showed a high stability in water immiscible organic solvents. Lipase from P. simplicissimum is nonspecific and hydrolyses each of the three bonds of triacylglycerols.

UI MeSH Term Description Entries
D008049 Lipase An enzyme of the hydrolase class that catalyzes the reaction of triacylglycerol and water to yield diacylglycerol and a fatty acid anion. It is produced by glands on the tongue and by the pancreas and initiates the digestion of dietary fats. (From Dorland, 27th ed) EC 3.1.1.3.

D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
D010407 Penicillium A mitosporic Trichocomaceae fungal genus that develops fruiting organs resembling a broom. When identified, teleomorphs include EUPENICILLIUM and TALAROMYCES. Several species (but especially PENICILLIUM CHRYSOGENUM) are sources of the antibiotic penicillin. Penicilliums

D004790 Enzyme Induction An increase in the rate of synthesis of an enzyme due to the presence of an inducer which acts to derepress the gene responsible for enzyme synthesis. Induction, Enzyme
D006031 Glycosylation The synthetic chemistry reaction or enzymatic reaction of adding carbohydrate or glycosyl groups. GLYCOSYLTRANSFERASES carry out the enzymatic glycosylation reactions. The spontaneous, non-enzymatic attachment of reducing sugars to free amino groups in proteins, lipids, or nucleic acids is called GLYCATION (see MAILLARD REACTION).
