Gellan lyase () is an
enzyme with
systematic name ''gellan β-
D-glucopyranosyl-(1→4)-
D-glucopyranosyluronate lyase''.
This enzyme
catalyses the following process:
: Eliminative cleavage of β-
D-glucopyranosyl-(1→4)-β-
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 β-
D-4-deoxy-Δ
4-GlcA''p''-(1→4)-β-
DGlc''p''-(1→4)-α-
L-Rha''p''-(1→3)-β-
D-Glc''p''.
