FunFam 65373: Alginate biosynthesis protein Alg8

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Mannuronan synthase. [EC: 2.4.1.33]
GDP-alpha-D-mannuronate + ((1->4)-beta-D-mannuronosyl)(n) = GDP + ((1->4)-beta-D-mannuronosyl)(n+1).
  • The enzyme catalyzes the polymerization of beta-D-mannuronate residues into a mannuronan polymer, an intermediate in the biosynthesis of alginate.
  • It is found in brown algae and in alginate-producing bacterial species from the Pseudomonas and Azotobacter genera.
