On phycocyanin participation in the hill reaction of the blue-green alga synechococcus cedrorum

Abstract

Release of part of the phycocyanin from grana of Synechococcus cedrorum results in a total loss of the ability to liberate oxygen photochemically.

The experiments favour the view that, in the blue-green alga examined, the lamellae are composed of at least two proteinaceous components.
