Figure 1.

Current diversity of the cyclodipeptides produced by the CDPS family. The amino acids forming the cyclodipeptide ring are indicated in the one-letter code at the top and right. Previously identified cyclodipeptides are in blue, cyclodipeptides identified with the present set of CDPSs are in orange. Light colors indicate cyclodipeptides detected in low amounts (UV peak area at 214 nm less than 200). The distribution of cyclodipeptides according to NYH or XYP subfamilies is shown in Figure S1.
