Characterization of the Three PSII Fractions Obtained by Ni-Affinity Chromatography and Gel Filtration
| PSII Fractionsa | I | II | III | Core |
|---|---|---|---|---|
| Chlorophyll a/b (w/w)b | 3.22 ± 0.37 | 3.36 ± 0.24 | 4.30 ± 0.75 | 4.27 ± 0.13 |
| Neoxanthin/β-carotene (mol/mol) | 0.26 ± 0.13 | 0.25 ± 0.13 | 0.13 ± 0.03 | <0.001 |
| σPSII (Å2/quanta) | 366 ± 20 | 350 ± 26 | 163 ± 88 | ND |
a
PSII fractions were isolated from State 2–locked samples. Values shown are means of more than three measurements ± sd.
b
Chlorophyll concentrations were determined as described by Niyogi et al. (1997).
