K. Nishiyama et al., Reductive degradation of a [2Fe-2S] cluster of Chlorella ferredoxin studied by circular dichroism spectroscopy, CHEM LETT, (2), 1999, pp. 155-156
Chlorella ferredoxin is thermostable for several hours at 50 degrees C. How
ever, in the presence of 9,10-phenanthrorine or 2, 2'-bipyridine, the oxidi
zed [2Fe-2S] cluster of ferredoxin undergoes spontaneous reduction to the r
educed state without adding other reducing agents.
