  • Propionate metabolism and its relationship to leghemoglobin biosynthesis in soybean nodules

    Creator:
    Jackson, Earl Kenneth
    Abstract:
    Experiments are reported which demonstrate that a cobalt deficiency in R. meliloti results in a decreased cytochrome content of bacterial cells. It is concluded that the effect of cobalt deficiency on cytochrome content of Rhizobium cells and on the leghemoglobin content of nodules possibly may be explained by an effect...

  • Some properties of ribonucleotide reductase in Rhizobium species

    Creator:
    Cowles, Joe Richard, 1941-
    Abstract:
    Ribonucleotide reductase from Rhizobium meliloti has been partially purified and characterized. The enzymatic reduction of ribonucleotides to deoxyribonucleotides is dependent upon B₁₂ coenzyme and dihydrolipoate. B₁₂ coenzyme was more effective than B₁₂ coenzyme analogues in the reductase reaction. The affinity of the R. meliloti reductase system for B₁₂ coenzyme was...
