In eubacteria and eukaryotes, citrate synthase and succinate thiokinase exhibit a species-dependent diversity of structure, activity and regulation. These enzymes have now been examined in the archaebacteria and it is found that each of the three major subgroups, the extreme halophiles, the thermoacidophiles and the methanogens, possesses characteristic types of citrate synthase and succinate thiokinase. The observed patterns of structure and regulation of these two enzymes are compared across the three evolutionary lineages. © 1985.
