✦ Synopsis

Sunlight does chemistry in nanohybrids composed of CdS quantum dots (QDs) and enzyme P450~BSβ~. The hybrids, which are self‐assembled through electrostatic interactions between the negatively charged QDs and the positively charged His~6~‐marked P450, produce hydroxyl and superoxide radicals upon irradiation. In their Communication on page 504 ff., B. I. Ipe and C. M. Niemeyer report that these reactive oxygen species activate P450 to catalyze the monooxygenation of myristic acid. (Graphic prepared by P. Alhorn, B. Ipe, and K. Rabe.)
