PROSITE documentation PDOC00005
Protein kinase C phosphorylation site


In vivo, protein kinase C exhibits a preference for the phosphorylation of serine or threonine residues found close to a C-terminal basic residue [1,2]. The presence of additional basic residues at the N- or C-terminal of the target amino acid enhances the Vmax and Km of the phosphorylation reaction.
