Probable heat shock protein GrpE; Participates actively in the response to hyperosmotic and heat shock by preventing the aggregation of stress-denatured proteins, in association with DnaK and GrpE. It is the nucleotide exchange factor for DnaK and may function as a thermosensor. Unfolded proteins bind initially to DnaJ; upon interaction with the DnaJ-bound protein, DnaK hydrolyzes its bound ATP, resulting in the formation of a stable complex. GrpE releases ADP from DnaK; ATP binding to DnaK triggers the release of the substrate protein, thus completing the reaction cycle. Several round [...]

Chaperone protein DnaJ; Participates actively in the response to hyperosmotic and heat shock by preventing the aggregation of stress-denatured proteins and by disaggregating proteins, also in an autonomous, DnaK-independent fashion. Unfolded proteins bind initially to DnaJ; upon interaction with the DnaJ-bound protein, DnaK hydrolyzes its bound ATP, resulting in the formation of a stable complex. GrpE releases ADP from DnaK; ATP binding to DnaK triggers the release of the substrate protein, thus completing the reaction cycle. Several rounds of ATP-dependent interactions between DnaJ, D [...]

Putative chaperone protein dnaJ. homology to dnaJ of E. coli of 32% (sprot|DNAJ_ECOLI) Acts as a co-chaperone. Stimulates jointly with grpE the ATPase activity of dnaK (By similarity). Pfam: DnaJ domain, DnaJ central domain (4 repeats), DnaJ Cterminal region no singal peptide no TMHs; Family membership.

NifU-related 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.

Probable chaperon protein HtpG; Molecular chaperone. Has ATPase activity.

Fdx2 protein; Ferredoxin 2Fe-2S. Homology to fdx of E. coli of 70% (sprot|FER_ECOLI). Ferredoxin are iron-sulfur proteins that transfer electrons in a wide variety of metabolic reactions. Although the function of this ferredoxin is unknown it is probable that it has a role as a cellular electron transfer protein. Involved in the in vivo assembly of the Fe-S clusters in a wide variety of iron- sulfur proteins. InterPro: Ferredoxin (IPR001055); Adrenodoxin (IPR001055) Pfam: 2Fe-2S iorn-sulfur cluster binding domain no signal peptide no TMHs; High confidence in function and specificity.

Putative regulatory Protein yfhF, 72% identity (82% similarity) to TrEMBL;P36539 of E.coli. Has PF01521, HesB-like domain;(IPR000361, HesB_yadR_yfhF); This family includes HesB which may be involved in nitrogen fixation; the hesB gene is expressed only under nitrogen fixation conditions. Other members of this family include various hypothetical proteins of which P46847 and NP31774 also contains NifU-like domains NifU which is also involved in nitrogen fixation. In the gram-negative soil bacterium Rhizobium etli, the hesB-like gene iscN is required for nitrogen fixation; High confidence [...]

Putative two-component sensor kinase; Region start changed from 382943 to 383189 (246 bases).
