Plastocyanin in its oxidized
(1bxu) and reduced (1bxv) state from Synechococcus sp.
PCC 7942
- What structural elements
are present in the protein?
- What is the subunit composition?
- What is the coordination
geometry about each copper ion?
- What changes occur during
oxidation-reduction reactions? Hint: You may want to align the structures and check
distances.
