==Crystal structure of cytochrome C2 mutant G95E==
-
All class I c-type cytochromes studied to date undergo a dynamic process, in the oxidized state, which results in the transient breaking of the, iron-methionine-sulfur bond and sufficient movement to allow the binding, of exogenous ligands (imidazole in this work). In the case of Rhodobacter, capsulatus cytochrome c(2), the sixth heme ligand Met96 and up to 14, flanking residues (positions 88-100, termed the hinge region), located, between two relatively rigid helical regions, may be involved in, structural changes leading to a transient high-spin species able to bind, ligands. We have examined 14 mutations at 9 positions in the hinge region, of Rhodobacter capsulatus cytochrome c(2) and have determined the, structure of the G95E mutant. Mutations near the N- and C-terminus of the, hinge ... [[http://ispc.weizmann.ac.il/pmbin/getpm?15196014 (full description)]]

== Function ==
 +
[https://www.uniprot.org/uniprot/CYC2_RHOCB CYC2_RHOCB] Cytochrome c2 is found mainly in purple, non-sulfur, photosynthetic bacteria where it functions as the electron donor to the oxidized bacteriochlorophyll in the photophosphorylation pathway. However, it may also have a role in the respiratory chain and is found in some non-photosynthetic bacteria.
