Evidence from high-pressure liquid chromatography for the existence of two ferredoxins in plants.
Crude ferredoxin preparations were obtained from blue-green algae, green algae, ferns, and higher plants. We analyzed the preparations by high-pressure liquid chromatography using two different types of columns, a hydrophobic phenyl-5PW column and an ion-exchange DEAE-5PW column. Two ferredoxins were detected in all plants analyzed. The ferredoxins from some plants were separated by use of both columns and those from others were separated by one of the two columns. Thus, there were three possible ways in which pairs of ferredoxins from a single species of plant could be separated. We suspect that there are two different ferredoxins in most if not all species of plants.
