   What initiation factors are involved in E coli mRNA synthesis?

   • In E. coli, this complex involves the small 30S ribosome, the mRNA template, three initiation factors that help the ribosome assemble correctly, guanosine triphosphate (GTP) that acts as an energy source, and a special initiator tRNA carrying N -formyl-methionine (fMet-tRNA fMet) (Figure \ (\PageIndex {4}\)).

   How does protein synthesis occur in bacterial cells?

   • Protein synthesis is coupled to growth phases of bacterial cells. During the exponentially growing phase, most ribosomes are actively engaged in protein synthesis. When the nutrient source is limited, bacterial cells enter into the stationary phase where 70S ribosomes are dimerized into inactive 100S dimers .

   What is the initiation complex of translation in bacteria?

   • Figure \ (\PageIndex {4}\): Translation in bacteria begins with the formation of the initiation complex, which includes the small ribosomal subunit, the mRNA, the initiator tRNA carrying N-formyl-methionine, and initiation factors. Then the 50S subunit binds, forming an intact ribosome.

   What are the main topics in protein synthesis in prokaryotes?

   • This chapter includes three major topics. The first one introduces the general steps of protein synthesis in prokaryotes, with a focus on mechanistic details of translation initiation, elongation, termination and ribosome recycling, and on the functional roles of individual translation factors involved in these steps.

   How is translation initiation promoted?

   • Translation initiation is promoted by IF1, IF2, and IF3, which mediate base pairing of the initiator tRNA anticodon to the mRNA initiation codon located in the ribosomal P-site. The mechanism of translation initiation differs for canonical and leaderless mRNAs, since the latter is dependent on the relative level of the initiation factors.

   Why is synthesis of proteins important?

   • The synthesis of proteins consumes more of a cell’s energy than any other metabolic process. In turn, proteins account for more mass than any other macromolecule of living organisms. They perform virtually every function of a cell, serving as both functional (e.g., enzymes) and structural elements.
