May act as a regulator of Fe-S biogenesis. | Chaperone protein hscA (Hsc66); Chaperone involved in the maturation of iron-sulfur cluster- containing proteins.

Seems to help targeting proteins to be folded toward HscA; Belongs to the HscB family. | 0.827 |
| cyaY | iscA | plu4642 | plu3281 | CyaY protein, which belongs to the frataxin family; Involved in iron-sulfur (Fe-S) cluster assembly. May act as a regulator of Fe-S biogenesis. | Iron-binding protein IscA; Is able to transfer iron-sulfur clusters to apo-ferredoxin. Multiple cycles of [2Fe2S] cluster formation and transfer are observed, suggesting that IscA acts catalytically. Recruits intracellular free iron so as to provide iron for the assembly of transient iron-sulfur cluster in IscU in the presence of IscS, L-cysteine and the thioredoxin reductase system TrxA/TrxB. | 0.473 |
| cyaY | iscS | plu4642 | plu3283 | CyaY protein, which belongs to the frataxin family; Involved in iron-sulfur (Fe-S) cluster assembly. May act as a regulator of Fe-S biogenesis. | Cysteine desulfurase; Master enzyme that delivers sulfur to a number of partners involved in Fe-S cluster assembly, tRNA modification or cofactor biosynthesis. Catalyzes the removal of elemental sulfur atoms from cysteine to produce alanine. Functions as a sulfur delivery protein for Fe-S cluster synthesis onto IscU, an Fe-S scaffold assembly protein, as well as other S acceptor proteins; Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. NifS/IscS subfamily. | 0.757 |

May act as a regulator of Fe-S biogenesis. | Fe/S biogenesis protein NfuA; Involved in iron-sulfur cluster biogenesis. Binds a 4Fe-4S cluster, can transfer this cluster to apoproteins, and thereby intervenes in the maturation of Fe/S proteins. Could also act as a scaffold/chaperone for damaged Fe/S proteins. | 0.618 |
| cyaY | nifU | plu4642 | plu3282 | CyaY protein, which belongs to the frataxin family; Involved in iron-sulfur (Fe-S) cluster assembly. May act as a regulator of Fe-S biogenesis. | NifU protein; A scaffold on which IscS assembles Fe-S clusters. It is likely that Fe-S cluster coordination is flexible as the role of this complex is to build and then hand off Fe-S clusters. | 0.922 |
