Low potential enzymatic hydride transfer via highly cooperative and inversely functionalized flavin cofactors

Abstract

The reduction of 2-naphtoyl-CoA to 5,6 dihydro-2-naphtoyl-CoA by 2-naphtoyl-CoA reductase is below the negative redox limit usually encountered in biological hydride transfer. Here, via X-ray crystallography and spectroscopic analysis, the authors elucidated the mechanism behind this.
