Abstrakt: The heterogeneous distribution of lipids and lipid-bound proteins in a plasma membrane has functional advantages. Herein, in a synthetic system, we demonstrate the assembly of three enzymes involved in cascade reactions, in response to the substrate of the first enzyme at the oil–water interface being stabilized by a Zn(II)-metallosurfactant. Then we show substrate-mediated catalytically-active cluster formation of the metallosurfactant in a binary mixture with another non-catalytic surfactant at the interface. The catalytic ability can be tuned by controlling clustering through the addition of phosphate ions. Overall this work demonstrates functionally diverse supramolecular nanoarchitectonics at the oil–water interface. [ABSTRACT FROM AUTHOR]
