rhamnogalacturonan I | Bacillus subtilis | 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 | rhamnogalacturonan I oligosaccharides with alpha-L-rhamnopyranose at the reducing end and 4-deoxy-4,5-unsaturated D-galactopyranosyluronic acid at the nonreducing end | - |

rhamnogalacturonan I | endotype eliminative cleavage, the YesW amino acid residues Asn152, Asp172, Asn532, Gly533, Thr534, and Tyr595 in the active cleft bind to rhamnose molecules through hydrogen bonds and van der Waals contacts | Bacillus subtilis | rhamnogalacturonan I oligosaccharides with alpha-L-rhamnopyranose at the reducing end and 4-deoxy-4,5-unsaturated D-galactopyranosyluronic acid at the nonreducing end | YesW releases a tetrasaccharide and larger saccharides as a major product | ? |
