Schematic diagram of the eight C. thermocellum DSM1313 scaffoldins. The genome of C. thermocellum DSM1313 (RefSeq NC017304.1) was screened for cohesin-containing proteins, and annotated by NCBI annotation software. New (as reported in Bras et al. ) and old terminologies are shown for the scaffoldins, together with their gene loci in strain DSM 1313 and their equivalents in the ATCC 27405 strain. CBM, carbohydrate-binding module; SLH, surface-layer homology; CSBM, cell-surface binding module. The numbers of cohesins in ScaA and ScaB (8 and 7, respectively) shown in the figure are according to the recent report of Hong et al.
