Enzyme Information

5.1.3.37
Mannuronan 5-epimerase.
based on mapping to UniProt Q44493
(Mannuronan)-beta-D-mannuronate = (alginate)-alpha-L-guluronate.
-!- 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.
