Binding Group - Finding Novel Fabric Binding Peptides
Goals
To discover short peptide sequences that allow enzyme-degrading peptides to bind to fabrics in order to concentrate them and increase their activity.
Methods
Phage display, bioinformatic analysis, quantitative ELISA
Results
- Isolated XX short peptides that bind cotton, linen, wool, polyester or silk.
- Discovered sequence motifs
- Quantified binding constants of 7 peptides for 5 fabrics with quantitative ELISA.
Binding domain group aims at finding novel peptides that can bind tightly and specifically to a particular fabric. We hope to improve the efficiency of enzymes tested
by the Enzymes search group by localizing and stabilizing the enzymes at the sites of action (fabric) by fusing the peptide sequences we find to those enzymes.
To achieve this goal we are using phage display technique.
Phage display describes a selection technique in which phages with genetic material encoding variants of peptide sequences express these peptides on the protein coat.
And based on the binding affinity of these peptides to a given target molecule by an in vitro selection process.
Therefore, the main focus of our group is to find novel peptide sequences that specifically bind to different fabrics.
Later, collaborate with other groups to optimize the efficiency of the potential enzymes they find on wine stained fabrics using our peptide sequences.
