Web2 Mar 2024 · The ribosome is one of the largest and most complicated enzymes in cells and is responsible for protein synthesis in all organisms on earth. The bacterial ribosome makes up 25% of the cell's dry mass ( 1 ), has a total mass of ∼2.5 MDa, and is composed of 3 ribosomal RNAs and 54 ribosomal proteins. WebRecruitment of mRNA to the 40S ribosomal subunit requires the coordinated interaction of a large number of translation initiation factors. In mammals, the direct interaction between eukaryotic initiation factor 4G (eIF4G) and eIF3 is thought to act as the molecular bridge between the mRNA cap-binding complex and the 40S subunit.
