Gellan tetrasaccharide unsaturated glucuronyl hydrolase (EC 3.2.1.179, UGL, unsaturated glucuronyl hydrolase) is an enzyme with systematic name beta-D-4-deoxy-Delta4-GlcAp-(1->4)-beta-D-Glcp-(1->4)-alpha-L-Rhap-(1->3)-beta-D-Glcp beta-D-4-deoxy-Delta4-GlcAp hydrolase. [1] [2] [3] This enzyme catalyses the following chemical reaction
- β-ᴅ-4-deoxy-Δ⁴-GlcAp-(1→4)-β-ᴅ-Glcp-(1→4)-α-ʟ-Rhap-(1→3)-β-ᴅ-Glcp + H2O 5-dehydro-4-deoxy-D-glucuronate + β-ᴅ-Glcp-(1→4)-α-ʟ-Rhap-(1→3)-β-ᴅ-Glcp
The enzyme releases 4-deoxy-4(5)-unsaturated D-glucuronic acid from oligosaccharides produced by polysaccharide lyases.
