The Effect of Electron Spin-Dependent Polarizability on Protein Activity

TL;DR

This paper reviews how electron spin affects protein activity through spin-dependent polarizability and suggests future research directions.

Contribution

The paper provides a review of experimental methods and findings on spin-dependent protein polarizability and its impact on reactivity.

Findings

Spin-dependent polarizability in proteins influences their reactivity.

Experimental methods have been developed to measure spin dependence in protein polarizability.

Future studies could explore how polarizability affects reactive sites in proteins.

Abstract

In recent years, it has been established that electron transport through a chiral system depends on spin. In several studies, it has further been established that charge polarization in proteins may affect their activity and, specifically, that this polarization is electron spin-dependent. Here, we review experimental methods that enable the spin dependence of protein polarizability to be recorded and describe results from several studies that indicate the importance of spin in controlling the reactivity of proteins. We conclude by suggesting why this spin dependence may be of importance and discussing how future studies might explore pathways within proteins by which polarizability affects protein reactive sites.
