Photosynthetic water oxidation in cytochrome b(559) mutants containing a disrupted heme-binding pocket.

The Journal of biological chemistry - 24 Aug 2001

Morais F, Kühn K, Stewart D H, Barber J, Brudvig G W, Nixon P J

Abstract excerpt

The role of cytochrome b(559) in photosynthetic oxygen evolution has been investigated in three chloroplast mutants of Chlamydomonas reinhardtii, in which one of the two histidine axial ligands to the heme, provided by the alpha subunit, has been replaced by the residues methionine, tyrosine, and glutamine. Photosystem two complexes functional for oxygen evolution could be assembled in the methionine and tyrosine...
