Bakteeriyada entomopathogenic bakteeriyada, Xenorhabdus nematophila, waxay keentaa difaac difaac cayayaanka la beegsanayo iyadoo la joojinayo dhaqdhaqaaqa fosfolipase A(2) (PLA(2)).Dhawaan, hiddo-wadaha PLA(2) ee difaaca jirka ku xiran ayaa laga aqoonsaday burka cas, Tribolium castaneum.Daraasadani waxay ku xidhay hiddo-wadaha PLA(2) ee bakteeriyada muujinta bakteeriya si ay u soo saarto ensaym dib-u-habayn ah.Dib-u-habaynta T. castaneum PLA (2) (TcPLA(2)) waxay soo bandhigtay waxqabadkeeda sifadeed ee enzyme-ka oo leh feejignaanta substrate, pH, iyo heerkulka jawiga.Sifooyinkeeda biochemical waxay la mid yihiin nooca qarsoodiga ah ee PLA(2) (sPLA(2)) sababtoo ah hawsheeda waxaa xannibay dithiothreitol (wakiilka yaraynta curaarta disulfide) iyo bromophenacyl bromide (sPLA (2) inhibitor gaar ah) laakiin maaha methylarachidonyl fluorophosphonate (nooc cytosolic gaar ah oo PLA(2) ah).Maraq dhaqameedka X. nematophila waxa ku jira PLA(2) is-hortaag (s), taas oo aad ugu badan warbaahinta laga helay marxaladda koritaanka bakteeriyada taagan.Qodobbada PLA(2) ee xannibaya waxay ahaayeen kuwo kulaylka u adkaysta oo laga soo saaray qaybaha aqueous iyo organic labadaba.Saamaynta PLA (2) -jajabka xannibaadda ee difaaca difaaca ee T. castaneum ayaa si la mid ah la mid ah taas oo ka dhalatay joojinta muujinta hidda-wadaha TcPLA (2) ee faragelinta RNA.
