Examples include ribosomes, nucleosomes, and many enzymes. nucleosidase Any of a class of enzymes which catalyze the decomposition of nucleosides into their component nitrogenous bases and pentose sugars. [12] nucleoside An organic molecule composed of a nitrogenous base bonded to a five-carbon sugar (either ribose or deoxyribose).
Ribosomes in eukaryotes contain 79–80 proteins and four ribosomal RNA (rRNA) molecules. General or specialized chaperones solubilize the ribosomal proteins and facilitate their import into the nucleus. Assembly of the eukaryotic ribosome appears to be driven by the ribosomal proteins in vivo when assembly is also aided by chaperones.

Ribosomes are the macromolecular machines that are responsible for mRNA translation into proteins. The eukaryotic ribosome, also called the 80S ribosome, is made up of two subunits – the large 60S subunit (which contains the 25S [in plants] or 28S [in mammals], 5.8S, and 5S rRNA and 46 ribosomal proteins) and a small 40S subunit (which contains the 18S rRNA and 33 ribosomal proteins).

A diagram showing mtDNA (circular) and mitochondrial ribosomes among other mitochondria structures. The mitochondrial ribosome, or mitoribosome, is a protein complex that is active in mitochondria and functions as a riboprotein for translating mitochondrial mRNAs encoded in mtDNA. The mitoribosome is attached to the inner mitochondrial membrane ...
