Cover Feature: Spectroelectrochemical Investigation of Cholesterol Oxidase from Streptomyces lividans at Different pH Values (ChemElectroChem 8/2019)

Abstract

The Cover Feature shows the gold capillary working electrode used for the spectroelectrochemical investigation of cholesterol oxidase (ChOx). The spectral changes collected during the ongoing reduction of ChOx (by mediated electron transfer, MET) in the presence of methylene blue as redox mediator are shown. Furthermore the titration curves at 374 and 454 nm for the reduction and reoxidation as well as the possible redox states of the FAD cofactor are depicted. More information can be found in the Article by M. Heinelt et al. on page 2174 in Issue 8, 2019 (DOI: 10.1002/celc.201801416).
