Chaperonin-mediated reconstitution of the phytochrome photoreceptor.


The native phytochrome photoreceptor was purified to homogeneity from etiolated seedlings of oat (Avena sativa L.) and used for renaturation experiments. Light scattering measurements showed that the GroEL molecular chaperone interacts with non-native phytochrome to suppress aggregation of the refolding polypeptide, following its dilution from a chaotrope… (More)
