Amino acids that carry charges on their side groups can bind to double stranded DNA (dsDNA) and change the strength of the double helix. Measurement of the DNA melting temperature (Tm) confirmed that acidic amino acids (Glu, Asp) weaken the H-bonds b

Endogenous peptides in the cyto- and nucleoplasm are formed upon the specific proteasomal degradation of nuclear proteins. These peptides are formed by short blocks of amino-acid residues with charged side groups and therefore a high local concentrat
