The histone H1 globular region. A possible supersecondary structure from spectroscopic and statistical studies.
The central region of the basic nuclear protein, histone H1, has a highly conserved amino acid sequence and a globular structure which is still not known at atomic resolution. A possible secondary and supersecondary structure was predicted by combining experimental measurements of circular dichroism and NMR spectroscopy with a statistical method based on the amino acid sequence. Our results showed the protein fragment as being highly structured and having a total alpha-helix content of about 40%.
