The human chromosomal protein HMG I contains two identical palindrome amino acid sequences.
The sequence of 105 amino acids of the human high mobility group chromosomal protein HMG I has been determined. The most striking feature of this sequence is two identical palindrome sequences: pro-arg-gly-arg-pro, which together with a third related sequence: gly-arg-pro-arg, may represent the binding sites of HMG I to clusters of A-T base pairs in DNA.
