WebWe construct peptide-nanoparticle conjugates (AuNP@CDs-Azo-peptide) by self-assembly of cyclodextrin capped gold nanoparticles (AuNP@CDs) and azobenzene terminated peptide (Azo-peptide) through host-guest interaction. AuNP@CDs-Azo-peptide has hydrolase-like activity, which is tuned by amino acid sequences. WebThe efficiency of an enzyme is largely influenced by the pH value of its surroundings. This is because the charge of its component amino acids changes with the change in the pH value. Each enzyme becomes active at a certain pH level. In general, most enzymes remain stable and work well in the pH range of 6 and 8.
