- Аннотация: 77K light-induced decrease of fluorescence at 760 nm (F760) was found in cyanobacterial membranes dependent on P700 redox state>. F760 is emitted by chlorophyll absorbing at 735 nm (Chi-735). This Chl form was found in high-molecular,250 kDa, PSI complex (CPlc); low-molecular, i00 kDa, complex (CPla) has no Chi-735 and contains mainly Chi-710 emitting at 730 nm. Photooxidation of PT00 is accompanied by F760 quenching as a result of energy migration from Chi-735 to oxidized P700. It is shown that T for F730 is independent of the redox state of P700 and is 500 ps in CPIa and 200 ps in CPIc. Oxidation of P700 in CPIc decreases t from 800 to 200 ps for F760. Thus Chi-735 is located in the internal antenna of CPIc.
