CAZypedia needs your help!
We have many unassigned pages in need of Authors and Responsible Curators. See a page that's out-of-date and just needs a touch-up? - You are also welcome to become a CAZypedian. Here's how.
Scientists at all career stages, including students, are welcome to contribute.

| − | '' | + | <!-- Mannuronan C5-epimerases are a group of enzymes that catalyze epimerization at the polymer-level of β-<font style="font-feature-settings: 'smcp'">d</font>-mannuronic acid residues (hereafter denoted M) into α-<font style="font-feature-settings: 'smcp'">l</font>-guluronic acid residues (hereafter denoted G) in alginate <cite>haug1969, larsen1971, haug1971</cite>. Alginate is an anionic polysaccharide made by brown seaweeds, some species of red algae, and the gram-negative bacterial genera ''Pseudomonas'' and ''Azotobacter'' <cite>Stanford1883, Gorin1966, Linker1966, govan1981, okazaki1982</cite>. The function of alginate in the different organisms are various, and related to structure, protection and surface adhesion \autocite{painter1983, campos1996, Pier2001, Harmsen2010}. Alginate is a copolymer of the two 1-4 linked epimers \autocite{Hirst1939, fischer1955, Drummond1962}, and by changing the composition of the two monomers the epimerases fine-tune the properties of the polymer \autocite{Ertesvaag1999}. --> |
