Crystallization of 70 S ribosomes and 30 S ribosomal subunits from Thermus thermophilus

[摘要]

Well-ordered three-dimensional crystals of 70 S ribosomes and 30 S ribosomal subunits from extremely thermophilic bacteria Thermus thermophilus have been obtained. Positively stained thin sections of the crystals have been analyzed by electron microscopy. Redissolved crystalline ribosomes and small ribosomal subunits reveal sedimentation constants of 70 S and 30 S, respectively, and are functionally active in the poly(U)-system.
