Structure of a polyisoprenoid binding domain from Saccharophagus degradans implicated in plant cell wall breakdown.

Saccharophagus degradans belongs to a recently discovered group of marine bacteria equipped with an arsenal of sugar cleaving enzymes coupled to carbohydrate-binding domains to degrade various insoluble complex polysaccharides. The modular Sde-1182 protein consists of a family 2 carbohydrate binding module linked to a X158 domain of unknown function. The 1.
