Two forms of glutamine synthetase in free-living root-nodule bacteria

Cell-free extracts of Rhizobium japonicum 61A76 contain two forms of glutamine synthetase (EC 6.3.1.2) which can be easily separated by isoelectric focusing. The more acid form (pI = 5.4), like the enzyme from E. coli , is stable at 50° and catalyses an ADP-dependent transferase reaction, whose inhi...
