Influence of the axial ligands on the spectral properties of P700 of photosystem I: a study of site-directed mutants.

Biochemistry - 24 Oct 2000

Abstract excerpt

Two histidines provide the axial ligands of the two chlorophyll a (Chl a) molecules which form the primary electron donor (P700) of photosystem I (PSI). Histidine 676 in the protein subunit PsaA, His(A676), and histidine 656 in subunit PsaB, His(B656), were replaced in the green algae Chlamydomna...
