Poly(beta-D-mannuronate) lyase

In enzymology, a poly(beta-D-mannuronate) lyase (EC number|4.2.2.3) is an enzyme that catalyzes the chemical reaction

:Eliminative cleavage of polysaccharides containing beta-D-mannuronate residues to give oligosaccharides with 4-deoxy-alpha-L-erythro-hex-4-enopyranuronosyl groups at their ends

This enzyme belongs to the family of lyases, specifically those carbon-oxygen lyases acting on polysaccharides. The systematic name of this enzyme class is poly(beta-D-1,4-mannuronide) lyase. Other names in common use include alginate lyase I, alginate lyase, alginase I, alginase II, and alginase. This enzyme participates in fructose and mannose metabolism.

tructural studies

As of late 2007, 3 structures have been solved for this class of enzymes, with PDB accession codes PDB link|1HV6, PDB link|1J1T, and PDB link|2CWS.
