|Mannuronate-specific alginate lyase.
|Alginate lyase I.|
|Poly(mana) alginate lyase.|
|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|
- The enzyme catalyzes the degradation of alginate by a beta-
- 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 22.214.171.124.
- Formerly EC 126.96.36.199.
