Phycobiliproteins, bilin variation, and group III CA regulation. (A) Phycocyanin and phycoerythrin (blue and red lines, and in vials) absorb in regions of the visible spectrum not well absorbed by chlorophyll or carotenoids. Attached bilins: PEB, phycoerythrobilin; PCB, phycocyanobilin. (B) Natural diversity in coloration of many different cyanobacterial species due to variation in their bilin content [photograph by Christophe Six. Reproduced with permission from Six et al. (2007) (Copyright 2010, Biomed Central Ltd.)]. (C) Group III CA regulation model for F. diplosiphon in red light, showing the asymmetric regulation of red-light active genes (orange) and green-light active genes (yellow) by the Rca and Cgi systems. Dashed line represents proposed repression by the Cgi system; yellow balls, phosphoryl groups; blue boxes, RcaC binding sites.
