A side view of the overall fold of the E259A mutant of potato endo-1,3- [beta]

-glucanase, emphasizing the catalytic cleft on the upper side of the molecule. The strands of the inner [beta]

-barrel (red) are surrounded by [alpha]

-helices (green). The subdomain region (magenta) extends beyond helix [alpha]
