Properties of yeast polygalacturonase

Archives of Biochemistry and Biophysics, 1954
Abstract Various properties were studied of the exocellular polygalacturonase of the yeast Saccharomyces fragilis (strain #351). Yeast polygalacturonase (YPG) was partially purified, until the activity was 2.03 (PGu)mgTN. YPG is not accompanied by pectinesterase.

Pectin-polygalacturonase in Citrus

Planta, 1976
Extracts from citrus [Citrus sinensis (L.) Osbeck] pedicles rated as containing polygalacturonase and cellulase gave activities both as measured with carboxymethylcellulose and with sodium polypectate. Gel electrophrosis of the extract demonstrated two region areas that contained cellulytic activity.

Polygalacturonases, polygalacturonase-inhibiting proteins and pectic oligomers in plant–pathogen interactions

Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2004
Polygalacturonases (PGs) are produced by fungal pathogens during early plant infection and are believed to be important pathogenicity factors. Polygalacturonase-inhibiting proteins (PGIPs) are plant defense proteins which reduce the hydrolytic activity of endoPGs and favor the accumulation of long-chain oligogalacturonides (OGs) which are elicitors of ...

TOMATO POLYGALACTURONASE EXTRACTABILITY

Journal of Food Biochemistry, 1995
The extractability of polygalacturonase (PG) activity from alcohol-insoluble solids (AIS) prepared from red-ripe tomato pericarp tissue was investigated using acetate (pH 4.5), citrate (pH 4.5) and MES (pH 6.0) buffers. The acetate buffer was also investigated with increasing concentrations of NaCl, CaCl 2 , MgCl 2 , ethylenediaminetetraacetic acid ...

Polygalacturonase activity ofAspergilli

Proceedings / Indian Academy of Sciences, 1951
1. Three strains ofAspergilli having good PG activity were isolated. 2. The conditions for maximum elaboration of PG were studied using synthetic liquid media as well as wheat bran. (i) The enzyme content was maximum after 4 days of growth; pH below 5 favoured the formation of enzyme.

Inhibition of polygalacturonase from Verticillium dahliae by a polygalacturonase inhibiting protein from cotton

Phytochemistry, 2001
An extracellular endo-polygalacturonase (PGase) [E.C. 3.2.1.15] was isolated from 18-day-old culture filtrates of Verticillium dahliae and partially purified using gel permeation chromatography. The band responsible for PGase activity was electrophoretically characterized as having a molecular mass of approximately 29 500 and an isoelectric point of 5 ...
