rhamnogalacturonase B
Reaction catalysed
Endotype eliminative cleavage of L-alpha-rhamnopyranosyl-(1->4)-alpha-D-galactopyranosyluronic acid bonds of rhamnogalacturonan I domains in ramified hairy regions of pectin leaving L-rhamnopyranose at the reducing end and 4-deoxy-4,5-unsaturated D-galactopyranosyluronic acid at the non-reducing end
Comment(s)
The enzyme is part of the degradation system for rhamnogalacturonan I in Bacillus subtilis strain 168 and Aspergillus aculeatus.
