Protein name |
RecName:
|
Full=Alginate lyase;
|
|
EC 4.2.2.3;
|
AltName:
|
Full=Poly(beta-D-mannuronate) lyase;
|
Flags:
|
Precursor;
|
|
case defined <Property:Membrane> and <Property:Membrane=2>
Function |
Catalyzes the depolymerization of alginate by cleaving the beta-1,4 glycosidic bond between two adjacent sugar residues via a beta-elimination mechanism. May serve to degrade mislocalized alginate that is trapped in the periplasmic space. |
else
Function |
Catalyzes the depolymerization of alginate by cleaving the beta-1,4 glycosidic bond between two adjacent sugar residues via a beta-elimination mechanism. |
end case
Catalytic activity |
Reaction=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.; EC=4.2.2.3; |
case defined <Property:Membrane> and <Property:Membrane=2>
Subcellular location |
Periplasm. |
end case
Similarity |
Belongs to the polysaccharide lyase 5 family. |
