Immunidiffusion and titration studies with antibodies against glutamine synthetase of the purple, photosynthetic bacterium Rhodobacter capsulatus E1F1 have been performed to compare the enzyme from different sources. The results obtained suggest that dodecameric glutamine synthetases from bacteria and cyanobacteria are antigenically related. However, there is not a marked antigenic relationship between glutamine synthetase of R. capsulatus and the octameric enzymes of eukaryotes.
