4.2.2.25: gellan lyase

This is an abbreviated version, for detailed information about gellan lyase, go to the full flat file.

Reaction

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-Delta4-GlcAp-(1->4)-beta-D-Glcp-(1->4)-alpha-L-Rhap-(1->3)-beta-D-Glcp. =
