Figure 4. CRISPR System of C. violaceum.

Figure 4

The schematic depicts the CRISPR/CAS locus of C. violaceum. Two CRISPR loci flank the six Cas genes (blue bars). The enlarged diagram shows the clamp formed in repetitive regions containing 28 nucleotides (brown bars) separated by a spacer sequence (green lozenge).
