FIG. 1.
The scaffoldin gene cluster in R. flavefaciens FD-1 and 17. (A) The scheme shows the organization on the genome of the scaC, scaA, scaB, and scaE genes. Scaffoldins of different sizes are indicated by the filled arrows. Numbers of amino acid residues for the given genes in the respective strain are shown. (B) Modular organization of the sca genes. The scaA and scaB genes contain multiple copies of cohesin modules (numbered). (C) Phylogenetic relationship among cohesin sequences from strains FD-1 and 17. The scale bar indicates the percentage of amino acid substitutions.
