Which enzyme forms peptide bonds between adjacents amino acids during polypeptide synthesis?

The enzyme responsible for forming peptide bonds between adjacent amino acids during polypeptide synthesis is called peptidyl transferase. This enzyme is found in the ribosome.


What is peptide transferase?

Peptidyl transferase is the enzyme that catalyzes the formation of peptide bonds between amino acids during translation of protein synthesis.


Why is galactokinase classified as a transferase?

Galactokinase is classified as a transferase because it catalyzes the transfer of a phosphate group from ATP to galactose, converting it into galactose-1-phosphate. This process involves the transfer of a functional group (the phosphate) rather than breaking or forming covalent bonds in the substrate itself, which is characteristic of transferases. Additionally, transferases are enzymes that facilitate the transfer of specific groups between molecules, and galactokinase fits this definition by transferring a phosphate group.


Who exhibits peptidyl transferase activity?

Peptidyl transferase activity is primarily exhibited by the ribosome, specifically by the ribosomal RNA (rRNA) component of the large subunit. This enzymatic activity catalyzes the formation of peptide bonds between amino acids during protein synthesis. In prokaryotes, this occurs in the 50S subunit, while in eukaryotes, it takes place in the 60S subunit. Thus, ribosomal RNA serves as a ribozyme facilitating this crucial biological process.


How does RNA work together with DNA?

Ribosomal RNA or rRNA is the main constituent of ribosomes. It performs the peptidyl transferase function of combining amino acids together via peptide bonds.

What does Oligosaccharide protein transferase do?

Oligosaccharide protein transferase is an enzyme that helps in the transfer of pre-assembled oligosaccharide chains from a lipid carrier to specific asparagine residues on newly synthesized proteins in the endoplasmic reticulum. This process is essential for proper protein folding and function.
