O fuifui u'amea-sulfur e galue e fai ma fa'ameamea o le tele o polotini, fa'atasi ai ma matafaioi mole mole eseese i sela prokaryotic ma eukaryotic.O masini fa'apitoa e fa'apotopotoina fuifui ma tu'u atu i mole mole taliaina mulimuli i se faiga fa'atulafonoina.I le prototypical Gram-negative bacterium Escherichia coli, o auala e lua o loʻo i ai nei iron-sulfur cluster assembly, iron-sulfur cluster (ISC) ma le sulfur assimilation (SUF), e fesoʻotaʻi vavalalata.O le ISC ala fa'atonutonu, IscR, o se fa'asologa o tusitusiga o le ituaiga helix-turn-helix e mafai ona fa'amaopoopoina se fuifui [2Fe-2S].Redox tulaga ma le uʻamea poʻo le sulfur avanoa e faʻafetaui ai le tulaga o le ligation o le labile IscR cluster, lea e fuafua ai se suiga i le DNA sequence specificity o le regulator: IscR o loʻo i ai le fuifui e mafai ona fusifusia i se aiga o gene promoters (ituaiga-1) ae o le fufuifui fomu e iloa na'o se vaega lona lua o fa'asologa (ituaiga-2).Ae ui i lea, o le biogenesis fuifui iron-sulfur i siama Gram-posititive e le o lelei tele, ma o le tele o meaola o lenei vaega e faʻaalia naʻo le tasi o le faʻapipiʻi faʻapipiʻi uʻamea-sulfur.O se tuusaunoaga mata'ina o le Gram-positive dissimilatory metal reducing bacterium Thermincola potens tulaga ese, lea e mafai ona iloa ai kenera mai faiga uma e lua, e ui ina i ai se fa'alapotopotoga e ese mai le siama Gram-negative.Na matou faʻaalia o se tasi o nei kenera e faʻapipiʻiina se IscR homolog galue ma e ono aʻafia i le faʻatonutonuina o le biogenesis uʻamea-sulfur i T. potens.O le faʻatulagaina ma le faʻataʻitaʻiga o le T. potens ma le E. coli IscR na faʻaalia ai se fausaga faʻapitoa tutusa ma faʻaalia ai se faʻasao faʻafuaseʻi o le faiga faʻapitoa o le faʻailoga faʻasologa o uiga o lenei vaega faʻapitoa o faʻatonuga faʻasalalauga.
