The Kappa-Carrageenase of P. Carrageenovora Features a Tunnel-Shaped Active Site: A Novel Insight in the Evolution of Clan-B Glycoside Hydrolases
Structure, 9:513-, 2001

PubMed Abstract: kappa-carrageenans are gel-forming, sulfated 1,3-alpha-1,4-beta-galactans from the cell walls of marine red algae. The kappa-carrageenase from the marine, gram-negative bacterium Pseudoalteromonas carrageenovora degrades kappa-carrageenan both in solution and in solid state by an endoprocessive mechanism. This beta-galactanase belongs to the clan-B of glycoside hydrolases.
