Chromophores and AM1_1557.

Chemical structures of (A) PCB and (B) BV. (C) Domain architecture of AM1_1557 according to a SMART motif analysis. (D) Cluster analysis of red/green, green/red and blue/green CBCR and phytochrome GAF domains. The position of AM1_1557g2 on the tree is highlighted in red. (E), His-tagged AM1_1557g2-PCB (PCB) and AM1_1557g2-BV (BV) purified from PCB- and BV-producing E. coli, respectively (2 μg protein per gel lane). Coomassie brilliant blue (CBB)-stained gel and in-gel Zn-dependent fluorescence assay (+Zn).
