Ferredoxin (Fd) was purified from this algae and characterized as a plant-type [2Fe-2S] Fd by physicochemical techniques. A high resolution (0.97A) three-dimensional structure of the CmFd D58N mutant molecule has been determined using the Fe-SAD phasing method to clarify the precise position of the Asn58 amide, as this substitution increases the electron-transfer ability relative to wild-type CmFd by a factor of 1.5. The crystal structure reveals an electro-positive surface surrounding Asn58 that may interact with ferredoxin NADP(+) reductase or cytochrome c.
