ENZYME: 4.2.2.3

Entry

EC 4.2.2.3                  Enzyme

Name

mannuronate-specific alginate lyase;
alginate lyase I;
alginate lyase;
alginase I;
alginase II;
alginase;
poly(beta-D-1,4-mannuronide) lyase;
poly(beta-D-mannuronate) lyase;
aly (gene name) (ambiguous);
poly[(1->4)-beta-D-mannuronide] lyase

Class

Lyases;
Carbon-oxygen lyases;
Acting on polysaccharides

Sysname

alginate beta-D-mannuronate---uronate lyase

Reaction(IUBMB)

Eliminative cleavage of alginate to give oligosaccharides with 4-deoxy-alpha-L-erythro-hex-4-enuronosyl groups at their non-reducing ends and beta-D-mannuronate at their reducing end.

Reaction(KEGG)

(other) R03706

Comment

The enzyme catalyses the degradation of alginate by a beta-elimination reaction. It cleaves the (1->4) bond between beta-D-mannuronate and either alpha-L-guluronate or beta-D-mannuronate, generating oligosaccharides with 4-deoxy-alpha-L-erythro-hex-4-enuronosyl groups at their non-reducing ends and beta-D-mannuronate at the reducing end. Depending on the composition of the substrate, the enzyme produces oligosaccharides ranging from two to four residues, with preference for shorter products. cf. EC 4.2.2.11, guluronate-specific alginate lyase.

History

EC 4.2.2.3 created 1965 as EC 4.2.99.4, transferred 1972 to EC 4.2.2.3, modified 1990, modified 2015
