Identification of the proteins interacting with tRNA in rat liver small ribosomal subunits

Abstract
Irradiation at 254 nm of the rat liver 40 S ribosomal subunit—poly(U)—Phe[32P]tRNA complex induced a covalent linkage of tRNA with a limited number of ribosomal proteins. After RNA hydrolysis, S10 was found to be the protein most highly labeled by radioactive nucleotides. Some radioactivity was also associated with protein S6-6a, S3a, S2 and S13–15.
