DE   gellan lyase.
CA   Eliminative cleavage of beta-D-glucopyranosyl-(1->4)-beta-D-
CA   glucopyranosyluronate bonds of gellan backbone releasing tetrasaccharides
CA   containing a 4-deoxy-4,5-unsaturated D-glucopyranosyluronic acid at the
CA   non-reducing end. The tetrasaccharide produced from deacetylated gellan
CA   is beta-D-4-deoxy-Delta(4)-GlcAp-(1->4)-beta-D-Glcp-(1->4)-alpha-L-Rhap-
CA   (1->3)-beta-D-Glcp.
CC   -!- The enzyme is highly specific to gellan, especially deacetylated
CC       gellan.
