Summary
The characterization of pea chloroplast ribosomal proteins has been carried out. The 30 S and 50 S subunits contain 24 and 32 ribosomal proteins respectively. These numbers are very similar to the numbers previously found for spinach chloroplast (Mache et al. 1980).
Chloroplast-synthesized ribosomal proteins have been determined using the light driven system of protein synthesis of Ellis and Hartley (1981). It is concluded that at least 6 ribosomal proteins of the 30 S and 5 proteins of the 50 S subunits are made in chloroplasts. The possibility that 4 additional ribosomal proteins (3 of the 30 S and 1 of the 50 S subunit) are chloroplastmade, is discussed.
