The Azurin p28 Peptide: Structure and Origin

Azurin is a small, blue copper protein secreted by various bacteria, notably *Pseudomonas aeruginosa*Azurin p28 peptide. The p28 peptide is a specific segment of this larger protein, typically encompassing amino acids 50 to 77. This 28-amino acid fragment has been identified as the active component responsible for the observed anticancer effects. The exact sequence of the p28 peptide is LSTAADMQGVVTDGMASGLDKDYLKPDD. This precise arrangement of amino acids dictates its three-dimensional structure and its ability to interact with cellular targets.Azurin-Based Peptide p28 Arrests the p53-HDM2 Interactions

Mechanism of Action: Targeting p53

A key mechanism by which the p28 azurin peptide exerts its anticancer effects is by interfering with the interaction between p53 and its negative regulator, HDM2 (or its homolog COP1). HDM2 normally targets p53 for degradation, thereby limiting its tumor-suppressive functions. The p28 peptide can bind to p53, or to HDM2, disrupting this interaction and preventing the proteasomal degradation of p53. This stabilization of p53 leads to its accumulation in cancer cells, where it can activate cell cycle arrest and apoptosis, ultimately leading to the elimination of cancerous cells.Solution structure of the anticancer p28 peptide in ... The formation of a p28:p53 complex is a central aspect of this mechanism.
