The Cytochrome b 6 f Complex

This chapter summarizes key features of the structural data, and develops insights into b6f complex function and biogenesis based on work performed in Chlamydomonas . The b6f complex forms a hetero-oligomeric integral membrane protein dimer, whose biogenesis involves the assembly of at least eight different protein subunits and two b-type hemes, two c-type hemes, one Fe2S2, one chlorophyll a, and one â-carotene per monomer. The available Chlamydomonas , higher plant and cyanobacteria genome information and mutants will certainly continue to contribute in a complementary manner to these studies.
