Modular architecture of Clostridium perfringens X82- and Doc-containing glycoside hydrolases. The FIVAR, Doc, and X82 modules used in this study are shaded in orange, light blue, and green, respectively. GHXX, glycoside hydrolase catalytic domains (shaded gray) where XX represents the family number; CBM32, family 32 carbohydrate-binding module; UNK, modules having unknown function and little sequence identity with other protein modules; F, FIVAR modules; Doc, dockerin-like modules; CBM40, family 40 carbohydrate-binding module; X82, cohesin-like family 82 X-module; FN3, fibronectin III-like module; CBM50, family 50 carbohydrate-binding module; ConA-like, Con A-like module; BIG_2, group 2 bacterial Ig-like domain.
