Abstract:
A comparative study of the 30S ribosomal subunit in the complex with protein S1 and the subunit depleted of this protein has been carried out by the hot tritium bombardment method. Differences in exposure of some ribosomal proteins within the 30S subunit depleted of S1 and within the 30S-S1 complex were found. It was concluded that protein S1 binds in the region of the neck of the 30S ribosomal subunit inducing a conformational change of its structure.

Ribosome Structure and Assembly
Ribosomes are composed of ribosomal RNA (rRNA) and proteins. In eukaryotes, rRNA is transcribed from genes in the nucleolus—a part of the nucleus that specializes in ribosome production. Within...

Ribosomal RNA Synthesis
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...
