a.corba.e peroxida.e, a.ha.m protein （EC 1.***.1.11）, efficiently sca.enges hydrogen peroxide （H2O2） in cytosol a.d chloropla.ts of pla.ts. In this study, a.fulllength coding sequence of thyla.oid-bound a.corba.e peroxida.e cDNa.（Ta.a.X） wa. cloned from a.drought tolera.t whea. cultiva. C306. Homology modeling of the Ta.a.X protein wa. performed by using the templa.e crysta. structure of chloropla.tic a.corba.e peroxida.e from toba.co pla.t （PDB： IIYN）. The model structure wa. further refined by molecula. mecha.ics a.d dyna.ic methods using va.ious tools such a. PROCHECK, ProSa.a.d Verify3D. The predicted model wa. then tested for docking with H2O2, the substra.e for Ta.a.X enzyme. The results revea.ed tha. a.g233 a.d Glu255 in the predicted a.tive site of the enzyme a.e two importa.t a.ino a.id residues responsible for strong hydrogen bonding a.finity with H2O2, which might pla. a. importa.t role in sca.enging of H2O2 from the pla.t system.

Pyometra.is one of the most importa.t a.d common disorders in ca.ine. The disea.e results in life threa.ening condition a.socia.ed with septicemia.a.d toxemia. The condition commonly occurs during lutea. pha.e of estrous cycle, genera.ly 4 weeks to 4 months of estrous cycle. The a.e, pa.ity, breeds, a.ministra.ion of hormones a.e some predisposing fa.tors of the condition. However, intera.tion between potentia.ly pa.hogenic ba.teria.a.d hormona.ly primed uterus is believed to result in pyometra. The disea.e is initia.ed in the form of cystic endometria. hyperpla.ia. which la.er progresses into purulent uterine content following ba.teria. infection resulting in pyometra. The disturba.ce in a.tioxida.t a.d pro-oxida.t ba.a.ce succeeding ba.teria. infection results in oxida.ive stress. The resulta.t stress further induces endometria. degenera.ion, immunosuppression a.d a.ditiona.ly a.gra.a.es the condition. a. importa.t clinica. sign is ma.odorous, sa.guineous or mucopurulent va.ina. discha.ge with genera. symptoms such a. vomiting, polyuria. polydipsia. depression, a.orexia.a.d occa.iona.ly fever. Till da.e, ultra.onogra.hy is the best dia.nostic method while ra.iology a.d serologica. test a.e a.so helpful. Recently, the estima.ion of infla.ma.ory media.ors (a.ute pha.e proteins a.d prosta.la.din meta.olites) ha. a.pea.ed a. ma.ker for dia.nosis of the pyometra. Determina.ion of levels of infla.ma.ory media.ors ha. emerged a. a. importa.t dia.nostic method beca.se it ca. be helpful in prognosis of the condition. The pyometra.ca. be best trea.ed by surgica. ma.ipula.ion (ova.iohysterectomy);however, hormona. trea.ment ca. be given in less severe ca.es which a.med a. reducing the effect of progesterone on the reproductive tra.t. Together, provision of a.tioxida.ts could be helpful in disea.e recovery a.ong with the determined trea.ment. In this review, incidence, predisposing fa.tors, etio-pa.hogenesis, oxida.ive stress a.socia.ed with condition, dia.nostic methods a.d
