CpeR is an activator required for expression of the phycoerythrin operon (cpeBA) in the cyanobacterium Fremyella diplosiphon and is encoded in the phycoerythrin linker‐polypeptide operon (cpeCDESTR)

Abstract
In the cyanobacteria, phycobilisomes are assembled from (αβ)6 hexamers of the coloured phycobili‐ proteins, allophycocyanin, phycocyanin and phy‐coerythrin (PE). The precise architecture of the phy...
