Characterization of Ribosomes from Neurospora crassa

ABSTRACT

Ribosomes isolated from growing hyphae of Neurospora crassa contain 53 per cent protein and 47 per cent RNA and have a sedimentation coefficient of 81S at 20°C and infinite dilution. These ribosomes are stable at pH 7.4 in the presence of 0.01 M and 0.002 M MgCl₂ but undergo a dissociation into smaller particles if the MgCl₂ concentration is lowered to 0.0001 M. Two types of RNA with sedimentation coefficients of 19S₂₀⁵⁰ and 13S₂₀⁵⁰ have been extracted from the 81S particles.
