Precise elimination of the N-terminal domain of histone H1.


ABSTRACT: The proteinase from mouse submaxillary gland was used to cleave total calf thymus histone H1 between residues 32 and 33. The C-terminal peptide, comprising residues 33 to the C-terminus, was purified and identified by amino acids analysis and Edman degradation. Spectroscopic characterization by n.m.r. for tertiary structure and by c.d. for secondary structure shows the globular domain of the parent histone H1 to be preserved intact in the peptide. It has therefore lost only the N-terminal domain and is a fragment of histone H1 comprising the globular plus C-terminal domains only. Precise elimination of only the N-terminal domain makes the fragment suitable for testing domain function in histone H1.
