Ko nga phosphatases pūmua Serine/threonine kua whakaahuatia i roto i te maha o nga huakita pathogenic he whākōkī tino whai wāhi i roto i nga huarahi whakawhiti tohu e whakawhirinaki ana ki te phosphorylation, me te hono tonu ki te kino o enei rauropi.I te tirotiro i te ira o Mycoplasma synoviae i kitea te noho mai o te ira (prpC) te whakawaehere i te phosphatase pūmua putative o te phosphatase phosphatase 2C (PP2C) pūmua.I konei, ka ripoatahia e matou he tohu matū-koiora katoa o te M. synoviae phosphatase (PrpC) me te mahi o nga katote whakarewa i roto i te hononga hanganga-mahi o tenei enzyme.Ko te tātari raupapa waikawa amino PrpC i whakaatu ko nga toenga katoa e uru ana ki te pokapū whakarewa dinuclear me te tuatoru o nga toenga whakarewa katote-whakarite, kua tiakina i roto i te PP2C phosphatases, kei roto i te PrpC.Ko te PrpC he pūmua monomeric ka taea te whakakore i te phospho-substrates ki te Mn(2+) katote 'whakawhirinaki.I whakaatuhia e te weaweti ngaaariki te pumau o te whaariki i nga mahana ngawari me te awe o nga katote Mn(2+) i roto i tenei taonga.I kii te tātaritanga spectrometry papatipu kia toru nga katote konganuku e herea ana ki te PrpC, e rua o aua katote me te ahua tonu o te hononga teitei.Ko te tātaritanga rereke o nga toenga whakarewa-whakarite tuatoru putative, Asp122 me Arg164, i whakaatu ko enei momo rerekee he ngoikore te herenga o nga katote konupora, a ko nga huringa e rua i pa ki te mahi PrpC phosphatase.E ai ki enei hua, ko te PrpC he mema phosphatase pūmua e whakawhirinaki ana ki te whakarewa me te pai ake o te ahua o te holo me te Asp122, ka uru pea ki te tuatoru o te waahi here-metara, he mea nui ki te mahi catalytic.
