Bacterial cellulose-binding domain-like sequences in eucaryotic polypeptides.

Abstract

The catalytic domain of endoglucanase II of Trichoderma reesei and the spore germination-specific polypeptide 270-11 of Dictyostelium discoideum contain amino acid sequences which share identity with the sequences of the cellulose-binding domains of several bacterial beta-1,4-glycanases. This is the first report of the presence of such sequences in eucaryotic polypeptides.
