Rhamnogalacturonan exolyase
Rhamnogalacturonan exolyase (EC 4.2.2.24, YesX) is an enzyme with systematic name alpha-L-rhamnopyranosyl-(1->4)-alpha-D-galactopyranosyluronate exolyase.[1][2] This enzyme catalyses the following chemical reaction
- Exotype eliminative cleavage of alpha-L-rhamnopyranosyl-(1->4)-alpha-D-galactopyranosyluronic acid bonds of rhamnogalacturonan I oligosaccharides containing alpha-L-rhamnopyranose at the reducing end and 4-deoxy-4,5-unsaturated D-galactopyranosyluronic acid at the non-reducing end.
