Abstract: | The rates of degradation of total soluble proteins in the free-living nematode, , have been estimated by following the loss of acid-insoluble insoluble radioactivity from protein during a nonradioactive chase period after initial labeling with 35S]methionine. These proteins appear to lose label kinetically as a homogeneous class in age-synchronized nematode populations. However, proteins are degraded more slowly in senescent cultures than in young cultures. Protein degradation rates decline progressively during nematode aging. These findings suggest that the protein degradative system in T. aceti may become partially defective with advancing age which may result in the accumulation of aberrant protein molecules in senescent organisms. |
