Figure 3: The conserved motifs of the cyanobacterial CCD enzymes. Schematic representation of motifs identified in cyanobacterial CCD enzymes using MEME motif search tool and ClustalW. The results were edited by hand. Length of box did not correspond to length of motif. Boxes represented the same or similar motifs that were labeled in the same color. (a) CCD7 from Synechococcus and Prochlorococcus marinus, (b) CCD7 from other cyanobacterial strains, (c) APCO, and (d) CCD1 and NCED.
