This is a display of rubredoxin. Rubredoxins are small redox proteins
which occur in certain bacteria and contain just one iron centre. The colour
of this protein in its oxidized form is an intense red, which is the result of a sulfur to iron
charge transfer transition (LMCT).
2-Cys- ligate the iron centre in a distorted tetrahedral fashion. Unlike other Fe-S centres, rubredoxin contains just one iron centre.
