About: Xanthan lyase

An Entity of Type: protein, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The enzyme xanthan lyase (EC 4.2.2.12) catalyzes the following process: Eliminative cleavage of the terminal β-D-mannosyl-(1→4)-β-D-glucuronosyl linkage of the side-chain of the polysaccharide xanthan, leaving a 4-deoxy-α-L-threo-hex-4-enuronosyl group at the terminus of the side-chain It belongs to the family of lyases, specifically those carbon-oxygen lyases acting on polysaccharides. Xanthan lyase was first identified and partially purified in 1987.

dbo:abstract
  • The enzyme xanthan lyase (EC 4.2.2.12) catalyzes the following process: Eliminative cleavage of the terminal β-D-mannosyl-(1→4)-β-D-glucuronosyl linkage of the side-chain of the polysaccharide xanthan, leaving a 4-deoxy-α-L-threo-hex-4-enuronosyl group at the terminus of the side-chain It belongs to the family of lyases, specifically those carbon-oxygen lyases acting on polysaccharides. Xanthan lyase was first identified and partially purified in 1987. Xanthan is a polysaccharide secreted by several different bacterial taxa, such as the plant pathogen Xanthomonas campestris, and it consists of a main linear chain based on cellulose with side chains attached to alternate glucosyl (glucose) residues. These side chains contain three monosaccharide residues. Xanthan lyase is produced by bacteria that degrade this polysaccharide, such as Bacillus, Corynebacterium, Bacteroides, Ruminococcaceae, and Paenibacillus species. (en)
