Serine/threonine protein phosphatases yafotokozedwa m'mabakiteriya ambiri a pathogenic monga ma enzymes ofunikira omwe amakhudzidwa ndi njira zotengera ma phosphorylation zomwe zimadalira kwambiri ndipo nthawi zambiri zimagwirizanitsidwa ndi virulence ya zamoyozi.Kuyang'ana kwa Mycoplasma synoviae genome kunawonetsa kukhalapo kwa jini (prpC) yomwe imasunga mapuloteni a phosphatase a protein phosphatase 2C (PP2C) subfamily.Pano, timapereka chidziwitso chathunthu cha biochemical cha M. synoviae phosphatase (PrpC) ndi ntchito yapadera ya ayoni achitsulo mu mgwirizano wa ntchito ya enzyme iyi.Kusanthula kwa PrpC amino acid kunawonetsa kuti zotsalira zonse zomwe zikukhudzidwa ndi dinuclear metal center ndi zotsalira zachitatu zogwirizanitsa zitsulo zachitsulo, zosungidwa mu PP2C phosphatase, zilipo mu PrpC.PrpC ndi puloteni ya monomeric yomwe imatha kutulutsa phosphorylate phospho-substrates ndi Mn (2+) ions' kudalira.Kusanthula kwa kukhazikika kwa kutentha kunawonetsa kukhazikika kwa ma enzyme pa kutentha pang'ono komanso mphamvu ya ayoni a Mn(2+) pamalowa.Kusanthula kwa ma spectrometry kunasonyeza kuti ma ion atatu azitsulo amamangiriza ku PrpC, awiri omwe amakhala ndi mawonekedwe ogwirizana kwambiri.Kusanthula kosinthika kwa zotsalira zachitatu zogwirizanitsa zitsulo, Asp122 ndi Arg164, zidawonetsa kuti mitundu iyi idawonetsa kumangiriza kofooka kwa ayoni a manganese, komanso kuti masinthidwe onsewa adakhudza ntchito ya PrpC phosphatase.Malinga ndi zotsatira izi, PrpC ndi membala wodalira zitsulo wa phosphatase wokhala ndi kukhazikika kwamphamvu mu mawonekedwe a holo komanso ndi Asp122, mwina wophatikizidwa ndi tsamba lachitatu lomanga zitsulo, lofunikira kuti zitheke.
