W3W4Q7

This peptide is expected to be a palladium reducing peptide. This peptide is modified by our team from the palladium reducing peptide Q7(Chiu et al., 2010). We implemented a double tryptophan structure at residues 3 and 4 as it was said that a double tryptophan is more effective than a single tryptophan structure in gold(Tan et al., 2010). We would like to investigate whether a double tryptophan will be more effective in palladium. We also want to investigate what effects will there have if we inserted the tryptophan residue at different positions.

This peptide has an isoelectric point of 6.0, a molecular weight of 0.94 kDa and hydrophobicity of 30.65. The serine residue at positions 7 is reported to be important in binding with palladium(Chiu et al., 2010). The tryptophan residue at positions 3 and 4 are reported to reduce palladium(Chiu et al., 2010). The amino acid sequence of the peptide is QQWWPIS.
