The relationship between histones F 2al and F 2a2 and the ancestral histone A peptide. Further evidence for the common origin of histones F 2al, F 2a2 and F 3.
The relationship between histones F 2al and F 2a2 becomes much more apparent if the alignment is not made between the total sequences but between the ancestral A peptide, reconstructed earlier for histone F 2al (IV) and F 2a2. 46.5% of the latter's sequence can thus be clearly connected with F 2al through this ancestral dodecapeptide. A parallel development of histones F 2al, F 2a2 and F 3 from the A peptide is proposed.
