The pi-pi stacking interaction is a weak interaction that plays an important role in protein structure stabilization and functionalization. This article discusses the effect of the pi-pi stacking interaction between alkylthio-substituted phenoxyl radical and an indole ring.
pi-pi stacking interaction is well-known to be one of the weak interactions. Its importance in the stabilization of protein structures and functionalization has been reported for various systems. We have focused on a single copper oxidase, galactose oxidase, which has the pi-pi stacking interaction of the alkylthio-substituted phenoxyl radical with the indole ring of the proximal tryptophan residue and catalyzes primary alcohol oxidation to give the corresponding aldehyde. This stacking interaction has been considered to stabilize the alkylthio-phenoxyl radical, but further details of the interaction are still unclear. In this review, we discuss the effect of the pi-pi stacking interaction of the alkylthio-substituted phenoxyl radical with an indole ring.
