Evidence for alteration of the membrane-bound ribosomes in Micrococcus luteus cells exposed to lead.


Micrococcus luteus cell exposed to PB(NO3)2 contained cytosol ribosomal particles and disaggregated membranal ribosomal particles as determined by ultracentirifugation and spectral studies. Approx. 60% of the membrane ribosome fraction from lead exposed cells had a sedimentation value of 8.4S. Cytosol ribosomes from lead exposed cells as well as membranal… (More)
