Pectin hydrolysis by certain salt-tolerant yeasts.
During the brine fermentation of cucumbers for pickles, Bell et al. (1950) have reported finding a fungal-type polygalacturonase-like enzyme which splits the polymer linkage of pectic substances. They definitely established this enzyme with the softening type of spoilage of salt-stock pickles brined under commercial conditions. With the identity of the softening agent known, an inquiry into its...
متن کاملSubcritical Water Hydrolysis of Peptides: Amino Acid Side-Chain Modifications
Previously we have shown that subcritical water may be used as an alternative to enzymatic digestion in the proteolysis of proteins for bottom-up proteomics. Subcritical water hydrolysis of proteins was shown to result in protein sequence coverages greater than or equal to that obtained following digestion with trypsin; however, the percentage of peptide spectral matches for the samples treated...
متن کاملStructural biology of pectin degradation by Enterobacteriaceae.
SUMMARY Pectin is a structural polysaccharide that is integral for the stability of plant cell walls. During soft rot infection, secreted virulence factors from pectinolytic bacteria such as Erwinia spp. degrade pectin, resulting in characteristic plant cell necrosis and tissue maceration. Catabolism of pectin and its breakdown products by pectinolytic bacteria occurs within distinct cellular e...
متن کاملPectin methylesterase, metal ions and plant cell-wall extension. Hydrolysis of pectin by plant cell-wall pectin methylesterase.
The hydrolysis of p-nitrophenyl acetate catalysed by pectin methylesterase is competitively inhibited by pectin and does not require metal ions to occur. The results suggest that the activastion by metal ions may be explained by assuming that they interact with the substrate rather than with the enzyme. With pectin used as substrate, metal ions are required in order to allow the hydrolysis to o...
