Abstract
In biomolecules, bifurcated hydrogen bonds typically involve the interaction of two donor protons with the two lone pairs of oxygen. Here, we present direct NMR evidence for a bifurcated H-bonding...

Hydrogen exchange during cell-free incorporation of deuterated amino acids and an approach to its inhibition
Hydrogen exchange during cell-free incorporation of deuterated amino acids and an approach to its inhibition
Abstract Perdeuteration, selective deuteration, and stereo array isotope labeling (SAIL) are valuable strategies for NMR studies of larger proteins and membrane proteins. To minimize scrambling of the label, it is best to use cell-free methods to prepare selectively labeled proteins. However, when proteins are prepared from deuterated amino acids by cell-free translation in H2O, exchange reactions can lead to contamination of 2H sites by 1H from the solvent. Examination of a...
