Polygalacturonase from Sitophilus oryzae: Possible horizontal transfer of a pectinase gene from fungi to weevils

Journal of Insect Science, 2003
Endo-polygalacturonase, one of the group of enzymes known collectively as pectinases, is widely distributed in bacteria, plants and fungi. The enzyme has also been found in several weevil species and a few other insects, such as aphids, but not in ...

The DENN Protein SMD1 Forms a Signalling Hub With Rab GTPase YPT1 to Regulate Diverse Biological Processes in Phytopathogenic Fungi and Serves as a HIGS Target for Crop Protection

Molecular Plant Pathology, Volume 27, Issue 6, June 2026.
The DENN domain‐containing protein SsSMD1 is highly conserved across phytopathogenic fungi. Functioning as a putative GEF for RAS GTPase SsYPT1, SsSMD1 orchestrates its activation to regulate cell wall integrity, sclerotia development, and virulence in Sclerotinia sclerotiorum.

Probing the role of cation-π interaction in the thermotolerance and catalytic performance of endo-polygalacturonases

Scientific Reports, 2016
AbstractUnderstanding the dynamics of the key pectinase, polygalacturonase, and improving its thermotolerance and catalytic efficiency are of importance for the cost-competitive bioconversion of pectic materials. By combining structure analysis and molecular dynamics (MD) simulations, eight mutagenesis sites having the potential to form cation-π ...

Continuous Hydrolysis of Pectate by Immobilized Endo-polygalacturonase in a Continuously Stirred Tank Reactor

Bioscience, Biotechnology, and Biochemistry, 1998
Enzymatic hydrolysis of pectate was carried out continuously to produce pectate oligosaccharides by immobilized endo-polygalacturonase in a continuous stirred tank reactor (CSTR) with high efficiency. The enzyme was immobilized on to chitosan beads by the absorption method, and the reaction was performed with an initial pectate concentration of 10 gl ...

Safety evaluation of the food enzyme arabinan endo‐1,5‐α‐l‐arabinanase from the non‐genetically modified Aspergillus tubingensis strain ARS R7‐60

EFSA Journal, Volume 24, Issue 4, April 2026.
Abstract The food enzyme arabinan endo‐1,5‐α‐l‐arabinanase (5‐α‐l‐arabinan 5‐α‐l‐arabinanohydrolase; EC 3.2.1.99) is produced with the non‐genetically modified Aspergillus tubingensis strain ARS R7‐60 by Shin Nihon Chemical Co., Ltd. The food enzyme was considered free from viable cells of the production organism. It is intended to be used in four food

Some Properties of Endo-polygalacturonase fromTrichosporon penicillatumSNO-3

Agricultural and Biological Chemistry, 1982
Some properties of the endo-polygalacturonase from Trichosporon penicillatum were investigated. The enzyme showed the highest activity around pH 5.0 and was stable at this pH up to 50°C. The enzyme catalyzed the hydrolysis of galacturonic acid oligomers as well as its polymer.
