CRYSTAL STRUCTURE OF THE PROTEIN SERINE/THREONINE PHOSPHATASE 2C AT 2 A RESOLUTION
Overview
Protein phosphatase 2C (PP2C) is a Mn2+- or Mg2+-dependent protein Ser/Thr, phosphatase that is essential for regulating cellular stress responses in, eukaryotes. The crystal structure of human PP2C reveals a novel protein, fold with a catalytic domain composed of a central beta-sandwich that, binds two manganese ions, which is surrounded by alpha-helices. Mn2+-bound, water molecules at the binuclear metal centre coordinate the phosphate, group of the substrate and provide a nucleophile and general acid in the, dephosphorylation reaction. Our model presents a framework for, understanding not only the classical Mn2+/Mg2+-dependent protein, phosphatases but also the sequence-related domains of mitochondrial, pyruvate dehydrogenase phosphatase, the Bacillus subtilus phosphatase, SpoIIE and a ...
