Gellan lyase

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-Δ4-GlcAp-(1→4)-β- D Glcp-(1→4)-α- L -Rhap-(1→3)-β- D -Glcp.
