Phosphoprotein Phosphatases (Tyrosine)

Protein tyrosine phosphatases (PTPs) and related enzymes (more than a hundred coded by the human genome) are more numerous than serine/threonine phosphatases. They belong to four families, three of which possess a conserved cysteine for catalysis and some conserved features of 3-dimensional structure. The catalytic mechanism of these PTPs involves the transient formation of a covalently phosphorylated enzyme.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
