H-Phe-Ile-OH is a polypeptide that can be found by peptide screening. Peptide screening is a research tool that pools active peptides primarily by immunoassay. Peptide screening can be used for protein interaction, functional analysis, epitope screening, especially in the field of agent research and development.

Protein Structure and Function:

Phe-Ile, or Phenylalanine-Isoleucine, is a dipeptide (a molecule formed by linking two amino acids) found in various proteins. Its specific properties, including its hydrophobic side chains, can contribute to protein structure and function in several ways:

• Protein folding: Phe-Ile's hydrophobic side chains often cluster within the interior of proteins, away from water, contributing to the overall folding pattern and stability.

• Protein-protein interactions: Phe-Ile residues can be involved in specific interactions between different protein molecules, influencing their assembly and function.
• Enzyme activity: In some enzymes, Phe-Ile sequences might be present near the active site, potentially influencing substrate binding and catalytic activity.

Peptide-based Therapeutics:

Phe-Ile can be a building block for short peptide sequences with potential therapeutic applications. Researchers are exploring the use of these peptides in various areas:

• Antimicrobial peptides: Certain Phe-Ile-containing peptides have shown antimicrobial activity against various bacteria and fungi, suggesting potential applications in developing new antibiotics or antifungals.

• Drug delivery systems: Phe-Ile sequences can be incorporated into drug delivery systems to improve drug targeting and efficacy.

Research Tools:

Phe-Ile can be a valuable tool in various research applications:

• Protein interaction studies: Synthetic peptides containing Phe-Ile can be used to probe protein-protein interactions, helping researchers understand protein function and signaling pathways.

• Model systems: Phe-Ile-containing peptides can be used as model systems for studying protein folding, aggregation, and other biophysical processes.
