UNSPECIFIED. (1992) PARTIAL UNCOUPLING OF ENERGY-TRANSFER FROM PHYCOERYTHRIN IN THE MARINE CYANOBACTERIUM SYNECHOCOCCUS SP WH7803. BIOCHIMICA ET BIOPHYSICA ACTA, 1099 (3). pp. 267-270. ISSN 0006-3002Full text not available from this repository.
Time-resolved fluorescence spectroscopy of the marine cyanobacterium Synechococcus sp. WH7803 showed that a significant fraction of the biliprotein phycoerythrin did not transfer its excitation energy to the photosynthetic reaction centres when the organism had been cultured in non-limiting light conditions and with excess nitrogen supplied as nitrate. We consider that this partial decoupling of energy transfer shows the capacity that this organism has to use a portion of the phycoerythrin as a nitrogen reserve, without the corresponding photo-oxidative damage that could occur from having a larger functional antenna than is required by photosynthesis.
