In the evolving field of peptide research, few molecules have garnered as much interest as the p28 fragment derived from the bacterial protein azurin. As someone who follows advancements in peptide chemistry, I have spent significant time reviewing th Azurin p28 peptide | p53: Tocris Bioscience e structural nuances of this fascinating molecule. When we discuss the p28 azurin peptide sequence, we are looking at a highly specific 28 amino acid fragment of azurin that has become a cornerstone in understanding cell-penetrating behavior.
Understanding the Structure and Identity
The p28 molecule is essentially a segment of the azurin protein, which is a 128-amino acid cupredoxin secreted by *Pseudomonas aeruginosa*. My interest in this peptide began when I discovered its unique physical Azurin a potent anticancer and antimicrobial agent isolated characteristics. Specifically, p28 is an amphipathic, α-helical, cell-penetrating peptide (often referred to as a CPP).
When analyzing the p28 sequence (28 aa), it corresponds precisely to residues Leu50–Asp77. The p28 domain (Leu50-Asp77) is responsible for its ability to traverse cellular boundaries. From a technical standpoint, this azurin-derived cell-penetrating peptide p28 is a 2.9 k Noncationic peptides obtained from azurin preferentially D fragment. The primary sequence is often cited in literature as: Leu-Ser-Thr-Ala-Ala-Asp-Met-Gln-Gly-Val-Val-Thr-Asp-Gly-Met-Ala (followed by the remaining residues extending to Asp77).
Why the p28 Peptide Stands Out
In my research, I often encounter the term Azurin p28 peptide TFA, which represents the trifluoroacetate salt form commonly used in laboratory settings to ensure stability and solubility. The p28 is an amphipathic 2.9 kD fragment CPP derived from the protein azurin that exhibits a remarkable ability to interact with intracellular proteins.
One of the most compelling aspects of this peptide P28 is its interaction w Azurin p28 peptide TFAis a tumor-penetrated antitumor peptide. Azurin p28 peptide TFA redues proteasomal degradation of p53 through formation of a p28: p53 ith p53. It is widely documented that azurin/p28 stabilizing p53 is a key mechanism of interest for biochemists. Because p28 is a 28-amino acid peptide fragment that mimics certain binding motifs, it effectively acts as a peptide that replicates an amino acid sequence of the p53 binding protein azurin.
Technical Specifications
For those tracking the structural interactions, it is worth noting that p28 peptide residues in the sequence range of 1–4, 7–11, and 22–23 are critical for its functional binding capabilities. The p28 (aa 50–77; Leu50-Asp77) configuration allows it to maintain its α-helical structure, which is vital for its role as an Azurin p28 peptide.

The p28 is derived from Azurin, a 128 amino acid Cupredoxin, and its stability is often a point of discussion in biochemical circles. Whether you are looking at the p28 molecule for its mechanical properties or its unique helical folding, the consistency of the p28 sequence (28 aa) remains a reliable standard in peptide synthesis.
