CcaS, green light receptor


CcaS is a cyanobacteriochrome, which is known to chromatically regulate the expression of the phycobilisome linker gene (cpcG2) in Synechocystis (see references). It functions as the receptor for green light and is made up of a N-terminal transmembrane helix, a cyanobactreria specific GAF domain, two PAS domains and a C-terminal histidine kinase. To be fully functional CcaS has to bind the chromophore Phycocyanobilin (PCB) with its GAF-domain. The GAF domain in this system has the ligation motif Cys-Leu, instead of the usual plant GAF-domain with Cys-His
