Role of the Nucleoid-Associated Protein H-NS in the Synthesis of Virulence Factors in the Phytopathogenic Bacterium Erwinia chrysanthemi

open access: yesMolecular Plant-Microbe Interactions, 2001
The ability of the enterobacterium Erwinia chrysanthemi to induce pathogenesis in plant tissue is strongly related to the massive production of plant-cell-wall-degrading enzymes (pectinases, cellulases, and proteases).

Identification of Potential IgE-Binding Epitopes Contributing to the Cross-Reactivity of the Major Cupressaceae Pectate-Lyase Pollen Allergens (Group 1)

open access: yesAllergies, 2022
Pectate-lyase allergens, the group 1 of allergens from Cupressaceae pollen, consist of glycoproteins exhibiting an extremely well-conserved three-dimensional structure and sequential IgE-binding epitopes.

Evaluation of the potential of free and immobilized thermophilic bacterial enzymes in the degradation of agro-industrial wastes [PDF]

open access: yesArchives of Biological Sciences, 2015
Agro-industrial wastes are potential starting materials for the production of useful value-added compounds, including prebiotic oligosaccharides. In this paper, we evaluated the potential of thermophilic bacterial pectin- and xylan-degrading ...

Identification and Characterisation of a Pectinolytic Enzyme from Paenibacillus xylanolyticus

open access: yesBioResources, 2014
Pectinolytic enzymes play an important role in the processing of lignocellulosic materials because of their ability to improve the access of cellulases to their substrate by removing pectins. The strain Paenibacillus xylanolyticus 2-6L3 was isolated from

Structure of pectate lyase A: comparison to other isoforms [PDF]

open access: yesActa Crystallographica Section D Biological Crystallography, 2002
Pectate lyase A is a virulence factor secreted by the plant-pathogenic bacteria Erwinia chrysanthemi. The enzyme cleaves the glycosidic bond of pectate polymers by a calcium-dependent beta-elimination mechanism. The crystal structure of pectate lyase A from E.

Synergism between Erwinia pectate lyase isoenzymes that depolymerize both pectate and pectin [PDF]

open access: yesMicrobiology, 1995
Phytopathogenic Erwinia bacteria cause tissue maceration by secretion of pectinolytic enzymes such as pectate lyase (PL). Sequencing of overlapping genomic fragments from Erwinia carotovora subsp. atroseptica established the organization of a 7.5 kbp region encoding PL isoenzymes.

Cloning and Characterization of an Esophageal-Gland-Specific Pectate Lyase from the Root-Knot Nematode Meloidogyne javanica

open access: yesMolecular Plant-Microbe Interactions, 2002
Root-knot nematodes (Meloidogyne javanica) are obligate sedentary endoparasites that must penetrate the host root to initiate their life cycle. Many enzymes are secreted by the nematode to facilitate host penetration; required enzymes may include pectate

Abundance and genetic diversity of microbial polygalacturonase and pectate lyase in the sheep rumen ecosystem. [PDF]

open access: yesPLoS ONE, 2012
Efficient degradation of pectin in the rumen is necessary for plant-based feed utilization. The objective of this study was to characterize the diversity, abundance, and functions of pectinases from microorganisms in the sheep rumen.A total of 103 unique

Colletotrichum gloeosporioides pelB Is an Important Virulence Factor in Avocado Fruit-Fungus Interaction

open access: yesMolecular Plant-Microbe Interactions, 2001
Colletotrichum gloeosporioides is an important pathogen of tropical and subtropical fruits. The C. gloeosporioides pelB gene was disrupted in the fungus via homologous recombination. Three independent isolates, GD-14, GD-23, and GD-29, did not produce or

The Role of Pectate Lyase and the Jasmonic Acid Defense Response in Pseudomonas viridiflava Virulence

open access: yesMolecular Plant-Microbe Interactions, 2007
Pseudomonas viridiflava is a common pathogen of Arabidopsis thaliana in wild populations, yet very little is known about mechanisms of resistance and virulence in this interaction. We examined the induced defense response of A.
