Qaaxada Mycobacterium waxay ku sii jiri kartaa tobanaan sano oo ay ku jiraan dadka martida loo yahay.Dariiqooyinka jawaab-celinta adag ee ku lug leh polyphosphate inorganic [poly (P)], kaas oo lagu farsameeyay laguna hydrolyzed by polyphosphate kinase (PPK) iyo exopolyphosphatase (PPX), siday u kala horreeyaan, ayaa la rumeysan yahay inay door muhiim ah ka ciyaaraan ilaalinta joogtada ah ee bakteeriyada.Waxaan halkan ku tusinaynaa in ururinta M. qaaxada poly(P) ay si ku meel gaadh ah ugu xidhan tahay xaddidaadda koritaanka unugyada.Waxaan sidoo kale u aqoonsanaa M. qaaxada Rv1026 inuu yahay exopolyphosphatase cusub oo leh firfircooni hydrolytic oo liddi ku ah silsiladda dheer ee poly(P).Isticmaalka habka tetracycline-inducible odhaahda si uu u garaaco muujinta Rv1026 (ppx2), waxaanu ogaanay in ururinta M. tuberculosis poly (P) ay keento koritaanka hoos u dhaca iyo hoos u dhigista isoniazid, korodhka caabbinta kulaylka iyo pH acid, iyo kor u qaadida badbaadada unugyada gudaha. inta lagu guda jiro caabuqa macrophage.Mikroskoobyada elektarooniga ah ee gudbinta, cadaadiska garaaca ppx2 wuxuu muujiyay kororka dhumucda gidaarka unugga, kaas oo lala xiriiriyay awood-u-yeelashada gidaarka unugyada ee dawooyinka hydrophilic halkii ay ka keeni lahaayeen bambooyin dareere ah ama qaab-dhismeedka biofilm oo la beddelo marka loo eego xakamaynta vector-ka madhan.Falanqaynta transcriptomic iyo dheef-shiid kiimikaadka ayaa shaaca ka qaaday hoos u dhaca dheef-shiid kiimikaadka ee garaacista px2 oo lagu garto qoraalka qoraalka iyo tarjumaada oo yaraada iyo hoos u dhaca heerarka glycerol-3-phosphate.Marka la soo koobo, poly (P) ayaa door muhiim ah ka ciyaara xakamaynta koritaanka qaaxada M. iyo hoos u dhaca dheef-shiid kiimikaadka waxayna gacan ka geysataa dulqaadka antibiyootiga iyada oo loo marayo isbeddelka derbiga unugyada. ppGpp, ayaa la rumeysan yahay inay dhexdhexaadinayso adkaysiga qaaxada Mycobacterium.Daraasaddan, waxaan ku aqoonsannay enzym novel ah (Rv1026, PPX2) oo ka mas'uul ah hydrolyzing poly (P) silsilad-dheer.Nadiifinta hidde-ahaaneed ee M. qaaxada oo ku yaraatay hidda-wadaha ppx2 ayaa muujisay heerarka poly(P) oo kordhay, kuwaas oo lala xiriiriyay xidhitaanka korriinka bakteeriyada hore iyo hoos u dhigista u nugulnaanta daroogada safka hore ee isoniazid, iyo sidoo kale badbaadada bakteeriyada oo kordhay inta lagu jiro soo-gaadhista walaaca. xaaladaha iyo gudaha macrophages.Marka loo eego cadaadiska xakamaynta, mutant-ku wuxuu muujiyay dhumuc kordhaysa ee gidaarka unugga iyo hoos u dhac ku yimaada daroogada.Muujinta hiddo-wadaha caalamiga ah iyo falanqaynta dheef-shiid kiimikaadka ayaa muujiyay hoos u dhigida muujinta qoraallada iyo mashiinnada tarjumaada iyo isbeddelka isticmaalka ilaha kaarboonka.Marka la soo koobo, nidaaminta dheelitirka poly(P) ayaa muhiim u ah samaynta joogtada ah ee M. qaaxada.
