Synthesis of two protected hexadecapeptides corresponding to the Gly 10 - and the Gly 1 , Lys 2 , Gly 3 -analogs of the fragment of sequence 1–16 of the N-terminal segment of the histone of fraction F2aI of calf thymus

Two protected hexadecapeptides corresponding to the Gly10- and the Gly1, Lys2, Gly3-analogs of the natural fragment of sequence 1–16 of the N-terminal segment of the histone of fraction F 2aI of calf thymus have been synthesized; their physical constants differ sharply from those of the hexadecapeptide corresponding to the natural fragment.
