Metal ion binding to peptides, proteins and enzymes
is a dominant feature of biology. We can model these 
interactions in gas phase with small-molecule 
substrates including amino acids, dipeptides and 
polypeptides. FELIX IRMPD spectra give structural 
information which is combined fruitfully with 
computations. Recent advances in forming 
+2 charge states of the gas-phase complexes have 
opened a new and rapidly advancing domain for the 
application of these techniques, and recent 
developments will be described.
