Redox Properties of Catalytically Generated Iminium Ions From α,β‐Unsaturated Aldehydes and Chiral Secondary Amines

European Journal of Organic Chemistry, Volume 29, Issue 24, 23 June 2026.
We present a rapid, operationally simple, and broadly applicable protocol for the catalytic formation and in situ electrochemical characterization of chiral a,b‐unsaturated iminium ions by cyclic voltammetry (CV). Using only 5 mol% of the aminocatalyst, we systematically measure the reduction potential of over 50 iminium intermediates, revealing how ...

Metal‐Dependent Effects and Crowding Robustness of Pseudomonas fluorescens Esterase I

ChemBioChem, Volume 27, Issue 11, 15 June 2026.
Pseudomonas fluorescens esterase I retains catalytic activity in metal‐rich and crowded environments, despite metal‐specific inhibitory effects. These findings highlight its robustness for biocatalytic applications in complex environments. Industrial biocatalysts are strongly influenced by their physicochemical environment, yet systematic studies on ...

Semi‐Rational Engineering of Formate Dehydrogenase Reveals Loop Dynamics as a Key Determinant of Thermostability

ChemBioChem, Volume 27, Issue 11, 15 June 2026.
Semi‐rational engineering yields a thermostable Bacillus simplex formate dehydrogenase variant (Q125F) with a 25‐fold longer half‐life at 60°C and strong resistance to chemo‐inactivation. Molecular dynamics reveal enhanced π–π interactions stabilizing a flexible loop and enabling efficient NADH regeneration for robust biocatalytic detoxification ...
