Photosystem I photochemistry: A new kinetic phase at low temperature.

P Setif1, P Mathis.   

Abstract

A new phase of charge recombination between the oxidized primary electron donor of photosystem I (P700(+)) and a reduced acceptor has been detected by flash absorption spectroscopy in PS I particles at low temperature. It occurs under highly reducing conditions (the secondary electron acceptors FA and FB and one or possibly two 'more primary' acceptors being prereduced) with a t1/2 of about 20 μs between 10 and 80 K.
