Some properties of the histone-like protein from Crypthecodinium cohnii (HCc).

ABSTRACT

The histone-like protein from Crypthecodinium cohnii (HCc) was examined in regard to its amino acid composition and the peptide pattern resulting from protease digestion. A revised amino acid composition indicated a higher lysine and arginine content and a lower glycine content than that determined previously. Comparative peptide mapping of HCc with HTa, a histone-like protein from Thermoplasma acidophilum, and with a histone-like protein from the dinoflagellate Gyrodinium dorsum showed significant differences in the peptide patterns produced.
