hscA | iscR | b2526 | b2531 | DnaK-like molecular chaperone specific for IscU; Chaperone involved in the maturation of iron-sulfur cluster- containing proteins. Has a low intrinsic ATPase activity which is markedly stimulated by HscB. Involved in the maturation of IscU; Belongs to the heat shock protein 70 family. | Isc operon transcriptional repressor; Regulates the transcription of several operons and genes involved in the biogenesis of Fe-S clusters and Fe-S-containing proteins. Transcriptional repressor of the iscRSUA operon, which is involved in the assembly of Fe-S clusters into Fe-S proteins. In its apoform, under conditions of oxidative stress or iron deprivation, it activates the suf operon, which is a second operon involved in the assembly of Fe-S clusters. Represses its own transcription as well as that of toxin rnlA. | 0.973 |

Has a low intrinsic ATPase activity which is markedly stimulated by HscB. Involved in the maturation of IscU; Belongs to the heat shock protein 70 family. | Cysteine desulfurase (tRNA sulfurtransferase), PLP-dependent; 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 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. Preferentially binds to disordered IscU on which the Fe-S is assembled, IscU converts to the structured state and then dissociates from IscS to transfer the Fe-S to a [...] | 0.978 |
hscA | iscU | b2526 | b2529 | DnaK-like molecular chaperone specific for IscU; Chaperone involved in the maturation of iron-sulfur cluster- containing proteins. Has a low intrinsic ATPase activity which is markedly stimulated by HscB. Involved in the maturation of IscU; Belongs to the heat shock protein 70 family. | Iron-sulfur cluster assembly scaffold protein; A scaffold on which IscS assembles Fe-S clusters. Exists as 2 interconverting forms, a structured (S) and disordered (D) form. The D- state is the preferred substrate for IscS. Converts to the S-state when an Fe-S cluster is assembled, which helps it dissociate from IscS to transfer the Fe-S to an acceptor. 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; Belongs to the NifU family. | 0.999 |
