cellulase (GH9)  M-CSA #559

Cellulase E4 from Thermomonospora is both exo- and endo- cellulases, catalysing the hydrolysis of cellulose. It contains both a family 9 catalytic domain, exhibiting an (alpha/apha)6 barrel fold and a family III cellulose binding domain, having an antiparallel beta-sandwich fold.

Defined by 4 residues: ASP:A-55ASP:A-58TYR:A-206GLU:A-424
