The Ribosomes of the Simian Malaria, Plasmodium knowlesi. I. Isolation and Characterization*

Abstract
Monomeric ribosomes, isolated from the monkey malaria Plasmodium knowlesi by the combined use of low concentrations of Triton X-100 and differential centrifugation, sedimented in the 80S range and could be dissociated into 60 and 40S subparticles. The base composition of the rRNA was typically protozoan; that is, low in guanine and cytosine residues.
