Cysteine in calf-thymus histones.
1. Calf-thymus histones contain cysteine, which is present almost entirely in the arginine-rich fraction F3 to the extent of about 1mole in 15000g. weight of the histone. 2. The cysteine in fraction F3 is readily available to thiol reagents and the protein yields an approximately equivalent amount of cysteic acid on oxidation with performic acid.
