A low-barrier hydrogen bond in the catalytic triad of serine proteases.

P A Frey et al.

Science (New York, N.Y.), 264(5167), 1927-1930 (1994-06-24)

Spectroscopic properties of chymotrypsin and model compounds indicate that a low-barrier hydrogen bond participates in the mechanism of serine protease action. A low-barrier hydrogen bond between N delta 1 of His57 and the beta-carboxyl group of Asp102 in chymotrypsin can

Electron spin-lattice relaxation in radicals containing two methyl groups, generated by gamma-irradiation of polycrystalline solids.

James R Harbridge et al.

Journal of magnetic resonance (San Diego, Calif. : 1997), 159(2), 195-206 (2002-12-17)

The effects of methyl rotation on electron spin-lattice relaxation times were examined by pulsed electron paramagnetic resonance for the major radicals in gamma-irradiated polycrystalline alpha-amino isobutyric acid, dimethyl-malonic acid, and L-valine. The dominant radical is the same in irradiated dimethyl-malonic

Anaerobic mineralization of quaternary carbon atoms: isolation of denitrifying bacteria on dimethylmalonate.

O Kniemeyer et al.

Applied and environmental microbiology, 65(8), 3319-3324 (1999-07-31)

The microbial capacity to degrade simple organic compounds with quaternary carbon atoms was demonstrated by enrichment and isolation of five denitrifying strains on dimethylmalonate as the sole electron donor and carbon source. Quantitative growth experiments showed a complete mineralization of
