Abstract/OtherAbstract:
Intact cells of Myxococcus xanthus were examined for de novo purine synthesis and salvage utilization. The cellular uptake rates of radioactive glycine (de novo purine precursor), adenine, and guanine were measured, and thin-layer chromatography and radioautography were used to examine cell extracts for de novo synthesized purine nucleotides. Intact vegatative cells, glycerol-induced myxospores, and germinating cells of M. xanthus CW-1 were able to carry out de novo purine and salvage synthesis. Germinating cells and glycerol-induced myxospores were metabolically more active or as active as vegetative cells with respect to purine anabolism. We conclude that M. xanthus is capable of synthesizing purine nucleotides and salvaging purines throughout the glycerol version of its life cycle.
