Description: The N-terminal protected and unprotected peptides MAHHEEQHG-NH2, Ac-MAHHEEQHG-NH2 from Hpn (Helicobacter histidine-rich protein) and MAHHEQQQQQQA-NH2, Ac-MAHHEQQQQQQA-NH2 from Hpn-like protein, respectively, were synthesized and their interactions with Cu2+ and Ni2+ ions were studied by potentiometric, UV–visible, CD, and EPR techniques. The studies have shown that because of their albumin-like sequence, unprotected peptides are very effective chelating agents for both studied metals. The presence of the hexa-glutamine sequence has very distinct impact on the stability of the complexes formed even if direct interactions with metal ions were not found.
