Front Cover: Asymmetric Ene‐Reduction by F420‐Dependent Oxidoreductases B (FDOR‐B) from Mycobacterium smegmatis (ChemBioChem 8/2023)

Abstract

Asymmetric ene-reductions of FDOR-Bs against α,β-unsaturated compounds reveal a novel class of ene-reductases utilizing the uncommon cofactor F420. Our study highlights the key role of Flavin/deazaflavin oxidoreductases B (FDOR-B) enzymes in acquiring stereocomplementarity with the Old Yellow Enzyme (OYE) family, leading to enhanced versatility of biocatalytic syntheses. The wider distribution of FDOR-Bs across bacterial genera compared to FDOR-A enzymes suggests a higher potential for identifying potent activity against industrially relevant substrates.
