Cover Story (view full-size image): The development of catalysts for the selective hydrolysis of proteins is challenging, yet important, for many applications in biotechnology and proteomics. The hydrolysis of hydrophobic proteins is particularly challenging as, due to their poor solubility, the use of surfactants is often required. In this study, the potential of catalyst systems based on the Zr(IV)-substituted Keggin polyoxometalate (Et2NH2)10[Zr(PW11O39)2] (Zr-K 1:2) and three different surfactants, which differ in structure and polarity, has been investigated toward hydrolysis of ovalbumin as a model protein. The study revealed that the presence of surfactants did not alter the selectivity of protein hydrolysis, but the efficiency of the reaction was affected differently depending on the type of surfactant.
