Polysaccharide lyase

UniProtKB accession:  B2FHL8

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Polysaccharide lyase that catalyzes the depolymerization of several anionic polysaccharides via a beta-elimination mechanism. Exhibits broad substrate specificity, catalyzing the degradation of not only alginate and poly-beta-D-mannuronate (poly-ManA), but poly-beta-D-glucuronate (poly-GlcA or poly-GlcUA) and hyaluronate (HA) as well. The oligosaccharide products formed by enzymatic cleavage are comprised mainly of disaccharides, with a lower abundance of trimers and pentamers. Is not active on poly-D-galacturonate, heparin and heparin sulfate.
