Fig. 3. (a) A crystal of the cyt b[6]f complex from the
cyanobacterium M. laminosus. The brownish nature relative to
crystals of the cyt bc[1] complex (30-33) is derived from one
molecule of chlorophyll a (18, 29) in the complex. (b)
Difference spectra of cyt f (ascorbate minus ferricyanide) and
cyt b[6] (dithionite minus ascorbate) in the cyt complex
obtained from crystals.
