KEGG ENZYME: 5.1.3.37

ENZYME: 5.1.3.37

Entry

EC 5.1.3.37                 Enzyme

Name

mannuronan 5-epimerase;
algG (gene name);
alginate epimerase;
C5-mannuronan epimerase;
mannuronan C-5-epimerase

Class

Isomerases;
Racemases and epimerases;
Acting on carbohydrates and derivatives

Sysname

[mannuronan]-beta-D-mannuronate 5-epimerase

Reaction(IUBMB)

[mannuronan]-beta-D-mannuronate = [alginate]-alpha-L-guluronate

Reaction(KEGG)

(other) R08693

Substrate

[mannuronan]-beta-D-mannuronate

Product

[alginate]-alpha-L-guluronate

Comment

The enzyme epimerizes the C-5 bond in some beta-D-mannuronate residues in mannuronan, converting them to alpha-L-guluronate residues, and thus modifying the mannuronan into alginate. It is found in brown algae and alginate-producing bacterial species from the Pseudomonas and Azotobacter genera.
