previous studies on regulation of the spc operon containing genes for ribosomal proteins have shown that s8 , encoded by the fifth gene of the operon in escherichia coli , is a translational repressor and regulates the synthesis of the third gene product ( l5 ) and distal gene products by acting at a site near the l5 mrna translation initiation site .
