Fig. 2. Promoter structure of cotC and domain structure of CudA and
CudA-like proteins. (A) Schematic of the Dictyostelium
cotC promoter. The positions of the three oligonucleotides (A, B and C),
the three CA-rich elements (CAEs; binding sequences for the transcription
factor GBF) and the regulatory TA-rich region are indicated. (B) Domain
structures of Dictyostelium CudA, Entamoeba ECudA and
Arabidopsis AtSHB.
