with
systematic name ''α-
L-rhamnopyranosyl-(1→4)-α-
D-galactopyranosyluronate endolyase''.
the following process:
: Endotype eliminative cleavage of
L-α-rhamnopyranosyl-(1→4)-α-
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
Dgalactopyranosyluronic acid at the non-reducing end.
The enzyme is part of the degradation system for rhamnogalacturonan I in ''
Bacillus subtilis'' strain 168 and ''
Aspergillus aculeatus''.
