Abstract

Abstract Persistent hole burning results obtained with the isolated chlorophyll-binding protein CP 34 induced under Fe stress in the cyanobacterium Synechococcus elongatus are presented. Excited state lifetimes were determined from zero phonon hole widths while chlorophyll–protein coupling was characterised from phonon side-band holes and inhomogeneously broadened function. Comparison of these values to those obtained previously with other chlorophyll–protein complexes from the same cyanobacterium supports an antenna role as well as chlorophyll-storage function of CP 34 in Fe limited cyanobacteria.
