Description
In enzymology, a poly(alpha-L-guluronate) lyase (EC 4.2.2.11) is an enzyme that catalyzes the chemical reaction: Eliminative cleavage of polysaccharides containing a terminal alpha-L-guluronate group, to give oligosaccharides with 4-deoxy-alpha-L-erythro-hex-4-enuronosyl groups at their non-reducing ends. This enzyme belongs to the family of lyases, specifically those carbon-oxygen lyases acting on polysaccharides.
