This domain binds to cellulose and to bacterial cell walls. It is found in glycosyl hydrolases and in scaffolding proteins of cellulosomes (multiprotein glycosyl hydrolase complexes). In the cellulosome it may aid cellulose degradation by anchoring the cellulosome to the bacterial cell wall and by binding it to its substrate [1]. This domain has an Ig-like fold [2].	Domain
