Respuesta :
During transpeptidation, nucleophilic attack occurs between the α-amine group in the A site and the esterified carbon in the P site
What is transpeptidation ?
A chemical process in which an amino acid residue or peptide residue is transferred from one amino compound to another. This process occurs when a protease reversibly converts one peptide to another.
- a process where one or more amino acids are transferred from one peptide chain to another, as in the case of a transpeptidase activity, or where a peptide chain itself is produced, as in the case of the production of a bacterial cell wall.
- Peptidoglycan glyco-syltransferases create the glycan strands (PGTs). The most popular class of antibiotics' fatal targets are enzymes termed transpeptidases (TPs), which produce the peptide crosslinks: using beta-lactams
