Determination of Polygalacturonase in Fruits

Nature, 1962
THE action of polygalacturonase1 is most commonly investigated either by viscometry2 or by the Willstatter-Schudel hypoiodite procedure3. Recently, Foda4 showed that the enzyme action was more conveniently and rapidly measured by using a colorimetric method based on that of Willaman and Davison5.

Studies on polygalacturonase of certain yeasts

Archives of Biochemistry and Biophysics, 1951
Abstract 1. 1. Among a considerable number of yeast species, representing nearly all yeast genera, only six were found which were capable of causing certain changes in pectin, when grown in its presence. These six cultures could all be identified with Saccharomyces fragilis (and a variety of this species) and its imperfect form Candida ...

Characterization of polygalacturonases

Gene, 1993
Lei et al. [Gene 117 (1992) 119-124] recently published the nucleotide sequence of the peh gene of Erwinia carotovora subsp. carotovora (Ecc) and a characterization of its product endopolygalacturonase (Peh). The gene appears highly similar to previously described peh sequences of Ecc [Hinton et al., Mol. Microbiol. 4 (1990) 1029-1036; Saarilahti et al.

Polygalacturonase activity in starfruit

Food Chemistry, 1987
Abstract Polygalacturonase (PGase) was extracted and partially purified from ripe starfruit (Averrhoa carambola, L.). 2·3- and 7·8-fold purifications were obtained following purification by Amicon ultrafiltration and Sephadex G-100 filtration, respectively.

Polygalacturonase inhibitors in bean pods

Phytochemistry, 1996
The amount of polygalacturonase-inhibiting protein (PGIP) was 14 times higher in bean pods than in etiolated hypocotyls. The PGIP was extracted from bean pods and partially purified by chromatography on columns of S-Sepharose. DEAE-Sephadex A-50, and Sephadex G-75.

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 ...

Differentiation of the Polygalacturonases of Aspergillus niger

Nature, 1952
IT has been long known that there is no close relationship between the physically and chemically measured action of polygalacturonase1. Jansen and MacDonnel2, Matus3, McColloch and Kertesz4, Reid5, Schubert6 and others have, from very different observations, suggested that the polygalacturonase preparations extracted from micro-organisms and plants ...

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.

Molecular Evolution of Fungal Polygalacturonase

1986
In plant-fungi interactions the establishment of basic compatibility occurs when a potential pathogen acquires functions that allow colonization of host plant species and/or suppression or neutralization of host resistance responses. Cultivar and race-specific resistance (specific compatibility) is generally considered as superimposed in host-parasite ...
