Title Μεταβολές που παρατηρούνται στα θυλακοειδή κατά τη φωτοεπαγόμενη φωσφορυλίωση του LHC-II

Abstract The stroma lamellar fraction (50.000xg supernatant) abtained by centrifugation from French press or digitonin disrupted chloroplasts after phosphorylation, found to be enriched in LHC-II components, can be separated into an upper, LHC-II-poor, and a lower, LHC-II-rich, thylakoid membrane zone, by sucrose density gradient ultracentrifugation. The results suggest that the enrichment in LHC-II of the stroma lamellar fraction, obtained from phosphorylated chloroplasts, reflects contamination of this fraction by destacked peripheral end grana membranes. The enhancement of the F730/F685 fluorescence emission ratio at 77 K, observed in chloroplasts on phosphorylation, may reflect the association of granal LHC-II with granal photosystem I.
