Room temperature photooxidation of β-carotene and peripheral chlorophyll in photosystem II reaction centre

R Litvin, D Bina, F Vacha - Photosynthesis research, 2008 - Springer
Differential kinetic absorption spectra were measured during actinic illumination of
photosystem II reaction centres and core complexes in the presence of electron acceptors
silicomolybdate and ferricyanide. The spectra of samples with ferricyanide differ from those
with both ferricyanide and silicomolybdate. Near-infrared spectra show temporary β-
carotene and peripheral chlorophyll oxidation during room temperature actinic illumination.
Peripheral chlorophyll is photooxidized even after decay of β-carotene oxidation activity and …

Room temperature photooxidation of\recke {beta}-carotene and peripheral chlorophyll in photosystem II reaction centre

R Litvín - 2009 - dspace.jcu.cz
Behaviour of photosystem II core complexes and isolated reaction centres upon actinic
illumination in the presence of artificial electron acceptors was examined. Differential
VISNIR absorption spectroscopy and HPLC was used to gain information on the state of
alternative electron donors (β-carotene and chlorophyll molecules).
