Fig. 8.16 Translation process of protein synthesis in prokaryotes.

Since many of the proteins made are enzymes, genes control the cell's internal chemistry.

Protein Synthesis (Translation)

4. The ribosomes have two sites, the A-site (amino acyl site) for the location of new amino acyl-tRNA (except for the fmet-tRNAfmet) and a P-site (peptidyl site) for locating the tRNA attached with newly synthesizing amino acid chain (di and polypeptide). The fmet-tRNAfmet after binding withIF2, is located on the initiation codon AUG at the P-site of the 30S subunit of ribosome which requires energy in the form of GTP. The role of IF1 is not
known. (In eukaryotes more initiation factors i.e., eIF1 to e1F6, are involved in nitiation).

The nucleolus and ribosomes form part of the proteinsynthesizing machinery of the cell

Is energy (ATP) required for protein synthesis?

The tRNA picks up specific from the cytoplasm and brings them into position on the surface of a ribosome where they can be joined together in specific order to make a specific protein.

The CPS 2017 Meeting will follow the biennial tradition of CPS Meetings, being an international gathering of scientists sharing interests in protein chemistry broadly defined, from synthetic methodology to applications in medicine and biomaterials. The meeting will provide an excellent networking platform for all participants and we particularly encourage students and post-docs to attend and benefit from the scientific environment.

Protein biosynthesis - Wikipedia

Better results will be obtained by repeating a coupling with fresh reagents (and changing coupling parameters if a low conversion was obtained) rather than by prolonging the reaction. Generally, coupling protocols may be changed in the course of a synthesis, especially when optimizing an SPPS.

What Is Protein Synthesis - Protein Synthesis

i.ρ-dependent Termination: In some prokaryotes, the termination of transcription is helped by a ρ (rho) protein that gets attached at the 5′ end of the newly synthesizing mRNA. The ρ then moves along the mRNA and induces the formation of hairpin loop near the 3′ end of mRNA due to the presence of inverted repeated sequences. This helps in the detachment of mRNA from the DNA (Fig. 8.9).

In a standard coupling procedure the HOBt ester is generated by the reaction between the protected amino acid and HOBt. The reaction is mediated by DCC or DIC.

In eukaryotes, the termination sites in DNA are present far away from the corresponding actual 3′ end of mRNA, thus, to produce HnRNA (heterogeneous nuclear RNA). The 3′ end of the mRNA is generated after the processing of HnRNA by snurp (small nuclear RNA-protein complex). In addition to these extra nucleotides at 3′ end, the HnRNA may also contain extra nucleotide sequences at the 5′ end and at the internal positions. These extra nucleotide sequences at internal positions are called introns, whereas, the nucleotide sequences in between the introns

Protein synthesis is the process of protein reproduction

Genes are sections of the DNA. Each gene has the code for creating a specific protein. The sequence of bases in the gene controls which amino acids are created and joined to make a specific new protein (or enzyme) molecule.
