Purity ~90% (SDS-PAGE). Cleaves the glycosidic bonds of gellan backbone and releases tetrasaccharide units of glucuronyl-glucosyl-rhamnosyl-glucose with unsaturated glucuronic acid at the non-reducing terminal. The enzyme is highly specific to the heteropolysaccharide gellan. Source: Recombinant protein corresponding to aa1-204 from geobacillus stearothermophilus Gellan Lyase, fused to His-Tag at N-terminal, expressed in Yeast. Molecular Weight: ~22.5kD AA
