4.2.2.23 | rhamnogalacturonan I |
responsible for an initial cleavage of the rhamnogalacturonan I region of plant cell wall pectin. Bacillus subtilis strain 168 secretes two rhamnogalacturonan lyases, YesW and YesX, extracellularly. YesW cleaves the glycoside bond of the rhamnogalacturonan chain endolytically, and the resultant oligosaccharides are subsequently converted to disaccharides, unsaturated galacturonyl rhamnose, through the exotype YesX reaction |
4.2.2.23 | rhamnogalacturonan I |
RGL4 is involved in the degradation of rhamnogalacturonan-I, an important pectic plant cell wall polysaccharide |
4.2.2.23 | rhamnogalacturonan I |
rhamnogalacturonan lyase produced by plant pathogenic and saprophytic microbes plays an important role in degrading plant cell walls |
4.2.2.23 | rhamnogalacturonan I |
rhamnogalacturonan lyases degrades rhamnogalacturonan I, a major component of pectin, through a beta-elimination reaction |
4.2.2.23 | rhamnogalacturonan I |
the enzyme is part of the degradation system of rhamnogalacturonan type I. YesW catalyzes the initial cleavage of the rhamnogalacturonan I main chain, and the resultant oligosaccharides are converted to disaccharides through the extracellular exotype YesX reaction. The disaccharide is finally degraded into its constituent monosaccharides through the reaction of intracellular unsaturated galacturonyl hydrolases YesR and YteR |
