ID 4.2.2.23 DE rhamnogalacturonan endolyase. AN alpha-L-rhamnopyranosyl-(1->4)-alpha-D-galactopyranosyluronide lyase. AN Rgase B. AN RG-lyase. AN rhamnogalacturonase B. CA Endotype eliminative cleavage of L-alpha-rhamnopyranosyl-(1->4)-alpha-D- CA galactopyranosyluronic acid bonds of rhamnogalacturonan I domains in CA ramified hairy regions of pectin leaving L-rhamnopyranose at the reducing CA end and 4-deoxy-4,5-unsaturated D-galactopyranosyluronic acid at the non- CA reducing end. CC -!- The enzyme is part of the degradation system for rhamnogalacturonan I CC in Bacillus subtilis strain 168 and Aspergillus aculeatus.
