Hoʻohana ʻia nā puʻupuʻu hao-sulfur ma ke ʻano he cofactors o kahi ākea o nā protein, me nā kuleana molekala like ʻole i nā cell prokaryotic a me eukaryotic.ʻO nā mīkini hoʻolaʻa e hōʻuluʻulu i nā pūʻulu a hāʻawi iā lākou i nā molekele ʻae hope loa i kahi kaʻina hana paʻa.I loko o ka prototypical Gram-negative bacteria Escherichia coli, nā ʻōnaehana hui hui hao-sulfur ʻelua, ʻo ka hao-sulfur cluster (ISC) a me ka sulfur assimilation (SUF), ua pili pili loa.ʻO ka mea hoʻoponopono ala ala ISC, ʻo IscR, kahi mea unuhi o ke ʻano helix-turn-helix hiki ke hoʻonohonoho i kahi pūʻulu [2Fe-2S].Hoʻololi nā kūlana Redox a me ka hao a i ʻole ka sulfur i ke kūlana ligation o ka puʻupuʻu labile IscR, ka mea e hoʻoholo ai i kahi hoʻololi i ka kikoʻī o ke kaʻina DNA o ka mea hoʻoponopono: hiki i ka cluster-containing IscR ke hoʻopaʻa i kahi ʻohana o nā mea hoʻolaha gene (type-1) ʻIke ʻia ka ʻano clusterless i kahi hui lua o nā kaʻina (type-2).Eia nō naʻe, ʻaʻole maikaʻi loa ke ʻano o ka biogenesis iron-sulfur cluster i loko o ka bacteria Gram-posititive, a ʻo ka hapa nui o nā mea ola o kēia pūʻulu e hōʻike i hoʻokahi wale nō o nā ʻōnaehana hui hui hao-sulfur.ʻO kahi ʻokoʻa ʻē aʻe, ʻo ia ka Gram-positive dissimilatory metal reducing bacterium Thermincola potens, kahi e ʻike ʻia ai nā genes mai nā ʻōnaehana ʻelua, ʻoiai me kahi hui ʻokoʻa mai kēlā o nā hua bacteria Gram-negative.Ua hōʻike mākou i kekahi o kēia mau genes e hoʻopili i kahi homolog IscR hana a pili paha i ka hoʻoponopono ʻana o ka biogenesis iron-sulfur cluster i T. potens.Ua hōʻike ʻia ke ʻano hoʻolālā a me ka biochemical o T. potens a me E. coli IscR i kahi hoʻolālā like ʻole a hōʻike i kahi mālama ʻike ʻole ʻia o ke ʻano hana kūʻokoʻa o ka hoʻokaʻawale ʻana i ke ʻano o kēia pūʻulu kūʻokoʻa o nā mea hoʻoponopono transcription.
