EC 5.1.3.37 Details
EC number
5.1.3.37
Accepted name
mannuronan 5-epimerase
Reaction
[mannuronan]-β-D-mannuronate = [alginate]-α-L-guluronate
Other name(s)
algG (gene name),
alginate epimerase,
C5-mannuronan epimerase,
mannuronan C-5-epimerase
Systematic name
[mannuronan]-β-D-mannuronate 5-epimerase
Comment
The enzyme epimerizes the C-5 bond in some β-D-mannuronate residues in mannuronan, converting them to α-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.
