The blue light using the flavin (BLUF) domain is one of the smallest photoreceptors in
nature, which consists of a unique bidirectional electron-coupled proton relay process in its …

Recent advances in neutron crystallographic studies have provided structural bases for
quantum behaviors of protons observed in enzymatic reactions. Thus, we resolved the …

Short hydrogen bonds, with heavy-atom distances less than 2.7 Å, are believed to exhibit
proton delocalization, and their possible role in catalysis has been widely debated. While …

The marine microbial catabolism of dimethylsulfoniopropionate (DMSP) by the lyase
pathway liberates∼ 300 million tons of dimethyl sulfide (DMS) per year, which plays a major …

Liquid water is a complex material with many anomalous properties. Three of these
anomalies are an abnormally high dielectric constant, an abnormally high boiling point, and …

The human cationic antimicrobial protein (hCAP) corresponding to the overlapping
sequences of 151–162 of hCAP named KR-12 peptide is the smallest portion of the only …

Rare tautomeric forms of nucleobases can lead to Watson–Crick-like (WC-like) mispairs in
DNA, but the process of proton transfer is fast and difficult to detect experimentally. NMR …

The formation of glycine amino acid on ice grains in space raises fundamental questions
about glycine chemistry in interstellar media. In this work, we studied glycine conformational …

There has been considerable debate on the existence of a low-barrier hydrogen bond
(LBHB) in the photoactive yellow protein (PYP). The debate was initially triggered by the …

Elucidation of the molecular mechanism of amine oxidases (AOx) will help to extend their
reactivity by rational design and their application to deracemization of various amine …
