13C-n.m.r. study of C hordein
The Biochemical Journal
|December 1, 1985
Summary
Researchers used carbon-13 nuclear magnetic resonance (13C-NMR) spectroscopy to analyze C hordein structure. The study identified five major residues and confirmed proline residues are in the trans configuration, supporting a beta-turn-rich structure.
Area of Science:
- Biochemistry
- Spectroscopy
Background:
- C hordein is a major protein in barley.
- Understanding its structure is crucial for its functional properties.
Purpose of the Study:
- To elucidate the structural characteristics of C hordein.
- To investigate the configuration of proline residues within the protein.
Main Methods:
- Utilized a combination of solution-state and solid-state 13C-nuclear magnetic resonance (NMR) spectroscopy.
- Analyzed the resulting NMR spectra to assign resonances to specific amino acid residues.
Main Results:
- The repetitive primary structure of C hordein yielded simple NMR spectra.
- Successfully assigned the majority of resonances to five major residues.
- Confirmed that proline residues exist in the trans configuration.
Conclusions:
- The findings support a beta-turn-rich secondary structure for C hordein.
- The structural data provides insights into hordein protein folding and function.
