Examples of transpeptidase in the following topics:

  • Damage to the Cell Wall

    • Penicillin acts by binding to transpeptidases and inhibiting the cross-linking of peptidoglycan subunits.
  • Peptidoglycan Synthesis and Cell Division

    • Cross-linking between amino acids in different linear amino sugar chains occurs with the help of the enzyme transpeptidase and results in a 3-dimensional structure that is strong and rigid.
  • RNA and Protein Synthesis

    • Cross-linking of the peptide side chains is then effected by transpeptidase enzymes.
    • Finally, transpeptidase enzymes reform the peptide cross-links between the rows and layers of peptidoglycan making the wall strong.
