摘要：

A lot of pep: Simple changes to the sequence of peptide nanostructures were found to maintain stability and enhance the activity of peptide-based palladium nanocatalysts. A hlstidine to alanine substitution in the peptide chain afforded an increase in turnover frequency from 2234 to 5224, which suggests that the peptide modulates the functionality of bioinspired nanomaterials.
