SummaryTwo-dimensional (2D)1H NMR experiments using deuterium labeling have been carried out to investigate the solution structure of ribonuclease HI (RNase HI) fromEscherichia coli (E. coli), which consists of 155 amino acids. To simplify the1H NMR spectra, two fully deuterated enzymes bearing several prototed amino acids were prepared from an RNase HI overproducing strain ofE. coli grown in an almost fully deuterated medium. One enzyme was selectively labeled by protonated His, He. Val. and… 

Complete assignments of magnetic resonances of ribonuclease H from Escherichia coli by double- and triple-resonance 2D and 3D NMR spectroscopies.

Characterizing the use of perdeuteration in NMR studies of large proteins: 13C, 15N and 1H assignments of human carbonic anhydrase II.

A general strategy for assigning backbone and side-chain resonances in a perdeuterated large protein is outlined, whereby this information can be used to glean more detailed structural information from the partially or fully protonated protein equivalent.

Individual ionization constants of all the carboxyl groups in ribonuclease HI from Escherichia coli determined by NMR.

All of the individual carboxyl groups in Escherichia coli ribonuclease HI, which is an enzyme that cleaves the RNA strand of a RNA/DNA hybrid, were pH-titrated, and their ionization constants (pKa) were determined from an analysis of the pH-dependent chemical shifts of the carboxy carbon resonances obtained from 1H-13C heteronuclear two-dimensional NMR.
