Serine / threonine protein phosphatases yakatsanangurwa mumabhakitiriya akawanda epathogenic sema enzymes anokosha anobatanidzwa mu phosphorylation-inotenderera chiratidzo chekushandura nzira uye inowanzobatanidzwa nehutachiona hwezvipenyu izvi.Kuongororwa kweMycoplasma synoviae genome kwakaratidza kuvapo kwejini (prpC) inokodha putative protein phosphatase yeprotein phosphatase 2C (PP2C) subfamily.Pano, isu tinoshuma yakazara biochemical characterization yeM. synoviae phosphatase (PrpC) uye kunyanya basa reion simbi muhutano-kushanda kwehukama hwe enzyme iyi.PrpC amino acid sequence analysis yakaratidza kuti zvese zvakasara zvinosanganisirwa mu dinuclear metal center uye putative yechitatu simbi ion-coordinating residues, yakachengetwa muPP2C phosphatases, iripo muPrpC.PrpC ipuroteni yemonomeric inokwanisa dephosphorylate phospho-substrates ine Mn (2+) ions 'kutsamira.Thermal kugadzikana kwekuongorora kwakaratidza kugadzikana kwe enzyme pane tembiricha yakapfava uye influence yeMn(2+) ions muchivakwa ichi.Mass spectrometry ongororo yakaratidza kuti maion matatu esimbi anosunga kuPrpC, maviri acho aine inooneka yakakwira-inofambidzana nguva dzose.Mutational ongororo yeiyo putative yechitatu simbi-yekubatanidza masara, Asp122 uye Arg164, yakaratidza kuti misiyano iyi yairatidza kushomeka kweiyo manganese ion, uye kuti shanduko dzese dzakakanganisa PrpC phosphatase chiitiko.Zvinoenderana nemhedzisiro iyi, PrpC inhengo inoenderana nesimbi yeprotein phosphatase ine kugadzikana kwakagadziridzwa mune holo fomu uye neAsp122, pamwe yakabatanidzwa mune yechitatu simbi-inosunga saiti, yakakosha pakuita basa rekuita.
