Theoretical Study of Heteroatom Resonance-Assisted Hydrogen Bond: Effect of Substituent on π-delocalization [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2010 The concept of Resonance Assisted Hydrogen Bond (RAHB), which usually occurs in b diketons, has a remarkable role in chemistry. These molecules, which contain heteroatom particularly O and N, are species with biological interest in protein folding and ...

Hydrogen-Bond-Promoted Hetero-Diels−Alder Reactions of Unactivated Ketones
, 2016 We report the first examples of hydrogen-bond-promoted acceleration of hetero-Diels−Alder reactions and the use of such catalysis for the hetero-Diels−Alder reactions of simple, unactivated ketones.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.
