The oxidation mechanism of native and denatured CaM, at a GCE, was investigated.
Native and denatured CaM presented the tyrosine amino acid residue oxidation peak.
Ca2 +-induced CaM conformational change on the electrochemical behaviour of CaM was evaluated.
Ca2 + bind with adsorbed CaM, on a graphite coated piezoelectric quartz crystal, demonstrated.
