Rhodospirillum molischianum, cytochromes

The shorter chains of the 82- to 86-residue cytochromes C550 (from Pseudomonas ), 6553, " and C555 (from Chlorohiumd ) as well as the longer 112-residue polypeptide of cytochrome C2 from Rhodospirillum rubrum have nearly the same folding pattern as that in mitochondrial cytochrome c. However, the 128-residue chain of the dimeric cytochrome c from Rhodospirillum molischianum forms an antiparallel four-helix bundle (Fig. 16-8). This is the same folding pattern present in the ferritin monomer (Fig. 16-3), hemerythrin (Fig. 2-22), and many other proteins including cytochrome 562 of E. coli ° Cytochrome/, which functions in photosynthetic electron transport, is also a c-type cytochrome but with a unique protein fold. ...
