Carrageenans, major cell wall polysaccharides of red macroalgae, are metabolised by marine heterotrophic bacteria through unclear mechanisms. Here, the authors identify an unusual polysaccharide-utilization locus encoding carrageenan catabolism in a marine bacterium, and characterise the complete pathway.
