Trapping of the S2 to S3 state intermediate of the oxygen-evolving complex of photosystem II.

Biochemistry - 23 May 2006

Ioannidis Nikolaos, Zahariou Georgia, Petrouleas Vasili

Abstract excerpt

Photosystem II preparations poised in the S(2)...Q(A) state produce no detectable intermediate during straightforward illumination at liquid helium temperatures. However, upon flash illumination in the range of 77-190 K, they produce a transient state which at -10 degrees C advances to S(3) or after rapid cooling to 10 K gives rise to a 116 G wide metalloradical EPR signal. The latter decays with half-times on...
