Polygalacturonase-Inhibiting Proteins Can Function as Activators of Polygalacturonase [PDF]

Molecular Plant-Microbe Interactions, 2004
The interaction between fungal endopolygalacturonases (EPGs) and polygalacturonase-inhibiting proteins (PGIPs) found in plant cell walls has been well established. The typical EPG/PGIP interaction is characterized by high affinity, reversibility, and a 1:

Pulsed light inactivation of polygalacturonase

Food Chemistry, 2019
Pulsed light is a non-thermal technology capable to inactivate enzymes. This study investigated the effect of pulsed light on the activity of polygalacturonase, and on the structure of the enzyme by means of fluorescence emission spectra, free sulphydryl detection and analysis of changes in parameter A and phase-diagram.

Revisiting interactions between polygalacturonases and polygalacturonase-inhibiting proteins and their effects on plant health: a review. [PDF]

Front Plant Sci
Polygalacturonases (PG) are recognized as key cell-wall-degrading enzymes in phytopathogenic fungi. Plants have a well-developed defense mechanism to counter invasive pathogens, yet such attacks harm the plants. The present review aims to understand the interactions of fungal polygalacturonases with their host invasions affecting plant health.

Insights into the Activity and Substrate Binding of Xylella fastidiosa Polygalacturonase by Modification of a Unique QMK Amino Acid Motif Using Protein Chimeras. [PDF]

PLoS ONE, 2015
Polygalacturonases (EC 3.2.1.15) catalyze the random hydrolysis of 1, 4-alpha-D-galactosiduronic linkages in pectate and other galacturonans. Xylella fastidiosa possesses a single polygalacturonase gene, pglA (PD1485), and X. fastidiosa mutants deficient

Polygalacturonase Production by Sarocladium strictum T4 Isolate using Apricot Pulp as Substrate in Non-Sterile Culture Conditions

Turkish Journal of Agriculture: Food Science and Technology, 2023
In this study, 34 molds showing pectin degradation activity were isolated from the soil of orchards, by several tests.  By using these isolates, pectinase group enzymes; studies on pectin lyase and polygalacturonase production were performed in the batch

Transcriptomic Responses of Rhizobium phaseoli to Root Exudates Reflect Its Capacity to Colonize Maize and Common Bean in an Intercropping System

Frontiers in Microbiology, 2021
Corn and common bean have been cultivated together in Mesoamerica for thousands of years in an intercropping system called “milpa,” where the roots are intermingled, favoring the exchange of their microbiota, including symbionts such as rhizobia. In this

Quantitative Genetic Analysis of Interactions in the Pepper–Phytophthora capsici Pathosystem

Molecular Plant-Microbe Interactions, 2022
The development of pepper cultivars with durable resistance to the oomycete Phytophthora capsici has been challenging due to differential interactions between the species that allow certain pathogen isolates to cause disease on otherwise resistant host ...

Production of polygalacturonase by Aspergillus niger BC23 isolated from Irvingia gabonensis (African mango) fruit [PDF]

Hemijska Industrija, 2016
Polygalacturonase was produced from Aspergillus niger BC 23 which was isolated from spoiled Irvingia gabonensis fruit. The influence of carbon substrates on enzyme production showed that the medium containing sucrose produced a maximum enzyme ...

Pear Juice Clarification Using Polygalacturonase from Beauveria bassiana : Effects on Rheological, Antioxidant and Quality Properties

Polish Journal of Food and Nutrition Sciences, 2022
Although pear is one of the most preferred fruits globally due to its high nutrient content, its juice products have not received equal consumer acceptability due to their undesirable haziness and turbidity. However, enzymatic treatment of juice has been

Production and Properties of a Thermostable, pH—Stable Exo-Polygalacturonase Using Aureobasidium pullulans Isolated from Saharan Soil of Algeria Grown on Tomato Pomace

Foods, 2016
Polygalacturonase is a valuable biocatalyst for several industrial applications. Production of polygalacturonase using the Aureobasidium pullulans stain isolated from Saharan soil of Algeria was investigated. Its capacity to produce polygalacturonase was
