Fig. 4

Absorption spectra, reported as optical density (OD) of OCP-BKT (recombinant Orange Carotenoidbinding Protein, OCP, purified from Chlamydomonas reinhardtii strain expressing both OCP and BKT, β-carotene ketolase) in water (orange line), YFP (Yellow Fluorescent Protein) in water (gold line) and OCP-BKT after ethanol (EtOH) extraction (red line). Grey line and violet lines represent spectra of OCP-BKT after ethanol extraction which was then lyophilized and resuspended respectively in water (grey line) or in ethanol (violet line). The data reported are representative of three independent experiments.
