Amaqoqo e-iron-sulphur asebenza njengama-cofactors ohlu olubanzi lwamaprotheni, anemisebenzi ehlukahlukene yamangqamuzana kuwo womabili amaseli e-prokaryotic kanye ne-eukaryotic.Imishini enikelwe ihlanganisa amaqoqo futhi iwahambise kuma-molecule wokugcina owamukelayo ngenqubo elawulwa ngokuqinile.Ku-bacterium ye-Gram-negative ye-prototypical i-Escherichia coli, izinhlelo ezimbili ezikhona zokuhlanganisa iqoqo le-iron-sulphur, iqoqo le-iron-sulphur cluster (ISC) kanye nemigudu ye-sulphur assimilation (SUF), zixhumene eduze.Isilawuli sendlela ye-ISC, i-IscR, iyisici sokuloba sohlobo lwe-helix-turn-helix engaxhumanisa iqoqo le-[2Fe-2S].Izimo ze-Redox kanye nokutholakala kwe-iron noma isulfure zimodela isimo sokuxhunyaniswa kweqoqo le-labile IscR, yona enquma ukushintsha kokucaciswa kokulandelana kwe-DNA yesilawuli: i-IscR equkethe iqoqo ingabophezela kumndeni wabathuthukisi bofuzo (uhlobo-1) kanti i-clusterless form ibona kuphela iqembu lesibili lokulandelana (uhlobo-2).Kodwa-ke, i-iron-sulfur cluster biogenesis kubhaktheriya ye-Gram-positive ayibonakali kahle, futhi izinto eziningi eziphilayo zaleli qembu zibonisa eyodwa kuphela yezinhlelo zokuhlanganisa iqoqo le-iron-sulfur.Okuhlukile okuphawulekayo i-Gram-positive dissimilatory metal eyingqayizivele enciphisa amagciwane e-Thermincola potens, lapho izakhi zofuzo kuzo zombili izinhlelo zingakhonjwa, nakuba ngenhlangano ephambukayo kuleyo yebhaktheriya e-Gram-negative.Sibonise ukuthi enye yalezi zakhi zofuzo ifaka ikhodi esebenzayo ye-IscR homolog futhi kungenzeka ibambe iqhaza ekulawuleni i-iron-sulfur cluster biogenesis ku-T. potens.Ukulingiswa kwesakhiwo nesamakhemikhali ezinto eziphilayo kwe-T. potens kanye ne-E. coli IscR kwembule ukwakheka okufanayo ngokuphawulekayo futhi kwembula ukulondolozwa okungalindelekile kwendlela eyingqayizivele yokucwasa okulandelanayo okuyingxenye yaleli qembu elihlukile labalawuli bokuloba.
