Abstract
In extracts of the unicellular cyanobacterium Gloeothece, the Fe-protein of nitrogenase can be separated by SDS-PAGE into two antigenically identifiab le components. Unlike the situation in photosynthetic bacteria such as Rhod ospirillum rubrum, these two forms do not arise from covalent modification of the protein by ADP-ribosylation. Rather, the Fe-protein of Gloeothece ni trogenase is subjected to modification by palmitoylation, (C) 2000 Federati on of European Biochemical Societies.
