Resonance Raman study of reconstituted carotenoproteins incorporating astaxanthin and 15,15''-didehydroastaxanthin.
???displayArticle.abstract???
Two reconstituted carotenoproteins have been studied by resonance Raman spectroscopy. They were prepared from the apoprotein of the Asterias rubens carotenoprotein, asteriarubin and either astaxanthin or 15,15''-didehydroastaxanthin. Spectral properties of dehydrocarotenoids are first discussed. The spectral properties of the complexes are compared to those of the free carotenoids and of other carotenoproteins containing astaxanthin, and possible protein-carotenoid interactions are discussed. Greater delocalisation of the pi-electron system in the central part of the polyene chain, and the role of lateral methyl groups in binding is emphasised.
