Abstract

Protein phosphorylation of light-harvesting complexes has been well-established as a mechanism for regulating light energy transfer in the chloroplasts of higher plants [1]. However, only recently has an analogous phenomenon been implicated for the chromatophore membranes of purple non-sulfur bacteria [2,3,4]. In particular, Allen and Holmes [4] have shown that electron transfer within the chromatophore membrane may be regulated by the degree of phosphorylation of the light harvesting complex [B875]. The results have been confirmed and a B875-kinase isolated from the cytoplasmic fraction.
