A colorimetric method to quantify endo-polygalacturonase activity
(Elsevier Science Inc, 2011-02)
We report a new colorimetric assay to quantify endo-polygalacturonase activity, which hydrolyzes polygalacturonic acid to produce smaller chains of galacturonate. Some of the reported polygalacturonase assays measure the ...
Inhibition of an extracellular polygalacturonase from Geotrichum candidum by a proteinaceous inhibitor isolated from lemon fruits
(Slovak University of Agriculture in Nitra. Faculty of Biotechnology and Food Sciences, 2017-03)
An extracellular polygalacturonase [EC 3.2.1.15], named PG-543, was purified from the culture of Geotrichum candidum IEV 543, a phytopathogenic fungi isolated from infected lemon. The molecular mass of the enzyme was ...
Inibidores de poligalacturonase (PGIPs) oriundos do feijão: produção recombinante e estudos funcionais
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Genética Evolutiva e Biologia Molecular - PPGGEvCâmpus São Carlos, 2019-03-01)
Pectic substances are components of the middle lamella of the plant cell wall and are composed of partially methyl-esterified galacturonic acid residues linked by α-1,4 glycosidic bonds. These substances are naturally ...
Alterações do abacate 'hass' submetidos à aplicação do 1-MCP
(2013)
The present study aimed at the conservation of avocado 'Hass' with the use of 1-methylcyclopropene (1- MCP). The fruits after harvest were selected and exposed to different concentrations of 1-MCP (200 ppm, 300 ppm and 400 ...
Purification and characterization of the exopolygalacturonase produced by Aspergillus giganteus in submerged cultures
(Springer Heidelberg, 2010-06-01)
Polygalacturonases are pectinolytic enzymes that catalyze the hydrolysis of the plant cell-wall pectin backbone. They are widely used in the food industry for juice extraction and clarification. Aspergillus giganteus ...

Estudos de poligalacturonases do fungo mutualista Leucoagaricus gongylophorus
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Química - PPGQ, 2014-08-12)
Polygalacturonases (PGases) are enzymes which hydrolyze glycosidic linkages - 1,4 between pectic acid residues, and are produced by plants, fungi, bacteria and yeasts. The fungus L. gongylophorus, Atta sexdens ant ...
