The class II cytochromes Rhodospirillum molischianum cytochrome c', Rhodopseudomonas palustris cytochrome c 556 and Agrohacterium tumefuciens (B 2a ) cytochrome c 556 have been investigated with a variety of spectroscopic techniques. The cytochrome c' was found to be high‐spin and the two cytochromes c 556 were found to be mainly low‐spin and sx‐coordinate with the fifth and sixth ligands being histidine and methionine. The implications of the different types of iron coordination are discussed.
