Amaqela e-iron-sulfur asebenza njenge-cofactors yoluhlu olubanzi lweeprotheni, ezineendima ezahlukeneyo zeemolekyuli kwiiseli zeprokaryotic kunye ne-eukaryotic.Oomatshini abazinikeleyo bahlanganisa amaqela kwaye bawahambise kwiimolekyuli zokugqibela zokwamkela kwinkqubo elawulwa ngokuqinileyo.Kwiprototypical ye-Gram-negative bacterium Escherichia coli, iindlela ezimbini ezikhoyo ze-iron-sulfur assembly cluster, i-iron-sulphur cluster (ISC) kunye ne-sulfur assimilation (SUF) pathways, zidibene ngokusondeleyo.Umlawuli wendlela ye-ISC, i-IscR, yinto ebhaliweyo yohlobo lwe-helix-turn-helix enokulungelelanisa i-cluster [2Fe-2S].Iimeko zeRedox kunye nokufumaneka kwentsimbi okanye isulfure zimodareyitha ubume be-ligation yeqela le-labile IscR, ethi yona imisele utshintsho kwi-DNA yolandelelwano oluchanekileyo lomlawuli: i-IscR ene-cluster inokubophelela kusapho lwabakhuthazi bemfuza (uhlobo-1) kanti i-clusterless form iqaphela kuphela iqela lesibini lolandelelwano (uhlobo-2).Nangona kunjalo, i-iron-sulfur cluster biogenesis kwi-Gram-positive bacteria ayibonakali kakuhle, kwaye uninzi lwezinto eziphilayo zeli qela zibonisa enye kuphela yeenkqubo zokuhlanganisa i-iron-sulfur.Umkhethe ophawulekayo yeyodwa iGram-positive dissimilatory metal yokunciphisa ibhaktheriya ye-Thermincola potens, apho imizila yemfuza evela kuzo zombini iinkqubo inokuchongwa, nangona kukho umbutho owahlukanisiweyo kuleyo yebhaktiriya yeGram-negative.Siye sabonisa ukuba enye yezi jini ifaka i-homolog ye-IscR esebenzayo kwaye kusenokwenzeka ukuba ibandakanyeka kulawulo lwe-iron-sulfur cluster biogenesis kwi-T. potens.Ukubonakaliswa kwesakhiwo kunye ne-biochemical ye-T. potens kunye ne-E. coli IscR ibonise ulwakhiwo olufana ngokumangalisayo kwaye yaveza ulondolozo olungalindelekanga lwendlela eyodwa yocalucalulo olulandelelanayo lweempawu zeli qela lahlukileyo labalawuli bokukhutshelwa.
