Several carbon metabolism enzymes were measured in cultured cells and bacteroids of Rhizobium meliloti 102F51 and in alfalfa root nodule cytosol. The enzyme activity levels of the pentose phosphate pathway were much higher than those of the Embden-Meyerhof-Parnas or Entner-Doudoroff pathways in extracts of cultured cells. The pattern of enzyme activities in the bacteroids was different from that of cultured cells.
