Protein kinase C-catalyzed phosphorylation of SIYRRGSRRWRKL peptide (with phosphorylated serine underlined) using ferrocene-labeled ATP (ATP-Fc) as a substrate. After a transfer of γ-phosphate-Fc group to the serine residue of the peptide, the surface-attached Fc groups are detected via EC techniques at thiol-modified gold electrodes.
