3.2.1.B42 | structure of a mutant lacking the family II cellulose binding domain, to 1.9 A resolution. The fragment contains both a family 9 catalytic domain, exhibiting an (alpha/alpha)6 barrel fold, and a family III cellulose binding domain, having an antiparallel beta-sandwich fold. The catalytic and cellulose binding domains interact. Upon binding of cellopentaose, cellotriose and cellobiose conformational changes occur |
