Complexes of divalent metal ions (Cu2+ and Ni2+) with histidine tripeptide complexes (HAA, AHA and AAH) are interesting gas-phase models for some of the most widely observed patterns of metal ion binding to peptides and proteins. Gas-phase structures

Ni(II) ions can be caged by surrounding peptide ligands in two basic binding patterns: the “iminol” (IM) binding pattern, where chelation occurs by deprotonated amide nitrogens, or the charge-solvated (CS) binding pattern, where chelation occurs

In the complex formed between the calcium cation (Ca2+) and a deprotonated HisHis dipeptide, the complex adopts a charge solvation (CS) structure. Ca2+, a weak binding main group metal cation, interacts with the oxygens of the peptide carbonyl moiety

The observed variety of metal-ion complexation sites offered by peptides reflects a basic tension between charge solvation of the ion by Lewis-basic chelating groups versus amide nitrogen deprotonation and formation of metal–nitrogen bonds. Gas-pha

Binding to proteins and peptides in condensed phases, it is normal for alkali and alkaline earth metal ions to interact preferentially with Lewis-basic oxygen, nitrogen and similar open chelation points, while late transition metals like cobalt, nick
