FIGURE 1.

Catalytic CAZyme SLH domain proteins from the genus Caldicellulosiruptor. Domain arrangement of these multidomain proteins is drawn to scale based on a prediction from the NCBI conserved domain database (93) and Pfam protein families database (94). Representative genes for each group containing more than one member are shown on the left. The number of Caldicellulosiruptor species genomes from the 12 completely sequenced to date that contain a member from each group is shown to the right. BIg, bacterial immunoglobulin-like (CL0159); Cadherin-like (pfam12733).
