Serine/threonine protein phosphatases ua faʻamatalaina i le tele o siama faʻamaʻi o ni enzymes taua o loʻo aʻafia i ala faʻaliliu faʻailoga faʻalagolago i le phosphorylation ma e masani ona fesoʻotaʻi ma le leaga o nei meaola.O se su'esu'ega o le Mycoplasma synoviae genome na fa'aalia ai le i ai o se gene (prpC) o lo'o fa'apipi'iina se polotini phosphatase o le protein phosphatase 2C (PP2C) subfamily.O iinei, matou te lipotia ai se faʻataʻitaʻiga atoatoa o meaola o le M. synoviae phosphatase (PrpC) ma le matafaioi faapitoa a ion uʻamea i le faʻatulagaina-galuega sootaga o lenei enzyme.PrpC amino acid sequence analysis na fa'aalia ai o toega uma o lo'o a'afia i totonu o le nuclear metal centre ma le fa'agasolo lona tolu o fa'aputuga fa'ameamea, fa'asaoina i PP2C phosphatases, o lo'o iai i le PrpC.PrpC ose polotini monomeric e mafai ona dephosphorylate phospho-substrates ma Mn(2+) ions 'faalagolago.O su'esu'ega fa'amautu vevela na fa'aalia ai le mautu o le enzyme i le vevela ma le a'afiaga o ion Mn(2+) i totonu o lenei meatotino.Ole su'esu'ega ole tele ole spectrometry na fautua mai ai e tolu ion u'amea e fusifusia ile PrpC, e lua o ia mea e foliga mai e maualuga le feso'ota'iga tumau.O suʻesuʻega faʻasolosolo o le toega lona tolu o le faʻamaopoopoina o uʻamea, Asp122 ma Arg164, na faʻaalia ai o nei fesuiaiga na faʻaalia ai le vaivai o le fusifusia o ion manganese, ma o suiga uma e lua na aʻafia ai le PrpC phosphatase.E tusa ai ma nei taunuʻuga, o le PrpC o se sui o le protein phosphatase e faʻalagolago i uʻamea faʻatasi ma se faʻaleleia atili o le faʻamautu i le holo ma le Asp122, atonu e aʻafia i le lona tolu o loʻo fusifusia uʻamea, e manaʻomia i gaioiga faʻamalosi.
