Abstract:
In order to quantitate and to determine the extent of binding of a heavy atom derivative to ribosomal particles and other components of protein biosynthesis, we prepared a 14C-radioactive labeled monofunctional undecagoldcluster. This cluster can be bound either to exposed sulfhydryl groups at the surface of the ribosomes and its subunits, or to high nucleophilic amino groups of nucleic acids as well as to proteins.

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,...
