Abstract
The relative concentration of biliproteins, phycobilisomes, chlorophyll a, and reaction centers I and II are reported for Neoagardhiella bailyei, a macrophytic red alga collected in the field and compared with Anacystis nidulans, a cyanobacterium cultured in the laboratory. The ratios of chlorophyll to reaction center I, of chlorophyll to reaction center II, and the mass of phycobiliprotein per reaction center II are quite similar in Neoagardhiella and Anacystis, supporting the concept that the red algal chloroplast is derived from a cyanobacterial progenitor. The ratios of reaction center I to reaction center II are about 2.3 in both species. The Anacystis phycobilisome has about 40% of the mass of the Neoagardhiella phycobilisome, 4.9 and 14.9 × 106 daltons, respectively. The reaction center II/phycobilisome ratio is about 1.7 in Anacystis and 4.1 in Neoagardhiella. Phycobilisome size and physical restrictions on phycobilisome packing may be a major constraint on the reaction center II-phycobilisome association and the assembly of the photosynthetic membrane in both the red algae and cyanobacteria.
