In this report, we determined protein tyrosine kinase (PTKs) activity in human epidermoid carcinoma cells (A431) by employing a novel electrochemical method using boron-doped diamond (BDD) electrodes that enables the electrochemical oxidation of tyrosine (Tyr), phosphorylated Tyr (Tyr-P) and sulfated

Oxidation of 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) by lactoperoxidase was found to be inhibited by tyrosine-containing random amino acid copolymers but not by tyrosine. Both electrostatic effects and polymer size were found to be important by comparison of negatively and positively charged copolymers

A simple and sensitive electrochemical biosensor was used to detect tyrosine oxidation induced by hydroxyl radicals generated by Fenton reaction (Fe(2+)/H(2)O(2)). Poly(glu, tyr) (4:1) peptides were immobilized on indium tin oxide (ITO) electrode surface via layer-by-layer assembly technique, and Os(bpy)(3)(2+)-mediated

Receptor tyrosine kinases (PTKs) play key roles in the pathogenesis of numerous human diseases, including cancer, and therefore PTK inhibitors are currently under intense investigation as potential drug candidates. PTK inhibitor screening data are, however, poorly comparable because of the

Protein-tyrosine kinases contain a catalytic loop Arg residue located either two or four positions downstream of a highly conserved Asp residue. In this study, the role of this Arg (Arg-318) in the protein-tyrosine kinase C-terminal Src kinase (Csk) was investigated.
