Pseudo-Jahn-Teller origin of the low barrier hydrogen bond in N2H7+ [PDF]
The microscopic origin and quantum effects of the low barrier hydrogen bond (LBHB) in the proton-bound ammonia dimer cation N(2)H(7) (+) were studied by means of ab initio and density-functional theory (DFT) methods.

Low-barrier hydrogen bond in photoactive yellow protein [PDF]
Low-barrier hydrogen bonds (LBHBs) have been proposed to play roles in protein functions, including enzymatic catalysis and proton transfer. Transient formation of LBHBs is expected to stabilize specific reaction intermediates. However, based on experimental results and theoretical considerations, arguments against the importance of LBHB in proteins ...

Breaking the low barrier hydrogen bond in a serine protease [PDF]
AbstractThe serine protease subtilisin BPN' is a useful catalyst for peptide synthesis when dissolved in high concentrations of a water‐miscible organic co‐solvent such as N, N‐dimethylformamide (DMF). However, in 50% DMF, the kcat for amide hydrolysis is two orders of magnitude lower than in aqueous solution.

Absorption wavelength along chromophore low-barrier hydrogen bonds
Summary: In low-barrier hydrogen bonds (H-bonds), the pKa values for the H-bond donor and acceptor moieties are nearly equal, whereas the redox potential values depend on the H+ position. Spectroscopic details of low-barrier H-bonds remain unclear. Here,

Low Barrier Hydrogen Bond Is Absent in the Catalytic Triads in the Ground State but Is Present in a Transition-state Complex in the Prolyl Oligopeptidase Family of Serine Proteases [PDF]
High frequency proton NMR spectra for two members of the prolyl oligopeptidase class of serine proteases, prolyl oligopeptidase and oligopeptidase B, showed that resonances corresponding to the active center histidine Nδ1H and Nε2H generally observed in ...
