Directionality of electron transfer in cyanobacterial photosystem I at 298 and 77K.

FEBS letters - 4 Jun 2015

Makita Hiroki, Hastings Gary

Abstract excerpt

Electron transfer processes in cyanobacterial photosystem I particles from Synechocystis sp. PCC 6803 with a high potential naphthoquinone (2,3-dichloro-1,4-naphthoquinone) incorporated into the A1 binding site have been studied at 298 and 77K using time-resolved visible and infrared difference spectroscopy. The high potential naphthoquinone inhibits electron transfer past A1, and biphasic P700(+)A1(-) radical...
