Sequence Investigation of the Clostridium Pasteurianum Nitrogenase: the Partial Amino Acid Sequence of Azoferredoxin
Our laboratory has been investigating the primary structures of various iron-sulfur proteins (l) with various long term goals in mind. These are: l) to provide essential data for structure-function investigations; 2) to provide evolutionary yardsticks for measuring the age of the iron-sulfur containing organisms; and provide necessary structural data for the X-ray crystallographers interested in determining the complete structures of the Fe-S proteins. Thus far, the Fe-S proteins sequenced have had relatively low molecular weights and perhaps it is time to extend the studies to proteins of greater complexity and with higher molecular weights. The protein chosen in the present investigation was the Clostridium pasteurianum nitrogenase and more specifically the azoferredoxin component.
