ENZYME entry: EC 4.2.2.25

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