Purification and Characterization of an Endo-Polygalacturonase fromAspergillus awamori

Bioscience, Biotechnology, and Biochemistry, 2000
An extracellular endo-polygalacturonase (PGase) produced by Aspergillus awamori IFO 4033 was isolated from the culture filtrate. The enzyme was purified to a homogeneous preparation with cation-exchange and size-exclusion chromatographies. Its properties were investigated, comparing them with that of recombinant pgx2 gene product, a PGase having ...

Determining Methyl-Esterification Patterns in Plant-Derived Homogalacturonan Pectins

Frontiers in Nutrition, 2022
Homogalacturonan (HG)-type pectins are nutrient components in plants and are widely used in the food industry. The methyl-esterification pattern is a crucial structural parameter used to assess HG pectins in terms of their nutraceutical activity.

Multiple Forms of Endo-Polygalacturonase fromSaccharomyces fragilis

Agricultural and Biological Chemistry, 1980
Three forms of endopolygalacturonase from Saccharomyces fragilis (Kluyveromyces fragilis) were separated by a procedure including adsorption on Amberlite IRC-50, CM Sephadex C-50 column chromatography and repeated preparative disc electrophoresis.

Enzyme activity in the micropylar region of Melanoxylon brauna Schott seeds during germination under heat stress conditions

Journal of Seed Science, 2020
: Recent studies indicate that global temperatures will rise substantially in the 21st century, leading to the extinction of several plant species, as plant metabolism and germination are greatly affected by temperature.

Purification and Characterization of an Endo-Polygalacturonase from a Mutant ofSaccharomyces cerevisiae

Bioscience, Biotechnology, and Biochemistry, 1999
An extracellular endo-polygalacturonase (PGase) produced by a mutant of Saccharomyces cerevisiae was isolated. The enzyme was regarded, immunologically, as a PGase belonging to the Kluyveromyces marxianus group. The enzyme had properties similar to the PGase from K. marxianus in heat and pH stability, and N-terminal amino acid sequence.
