STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

hscAFe-S protein assembly chaperone HscA; Chaperone involved in the maturation of iron-sulfur cluster- containing proteins. Has a low intrinsic ATPase activity which is markedly stimulated by HscB. (625 aa)    
Predicted Functional Partners:
dnaJ
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 [...]

Pnap_1564
TIGRFAM: ferredoxin, 2Fe-2S type, ISC system; PFAM: ferredoxin; KEGG: bxe:Bxe_B1439 (2FE-2S) ferredoxin.

htpG
Heat shock protein Hsp90; Molecular chaperone. Has ATPase activity.
 
 
 0.910
Pnap_3253
PFAM: heat shock protein DnaJ domain protein; KEGG: pol:Bpro_3897 heat shock protein DnaJ-like.
 
 0.903
Pnap_1566
TIGRFAM: iron-sulfur cluster assembly accessory protein; iron-sulfur cluster assembly protein IscA; PFAM: HesB/YadR/YfhF-family protein; KEGG: bxe:Bxe_B1441 HesB/YadR/YfhF, iron-sulphur cluster assembly protein IscA; Belongs to the HesB/IscA family.

grpE
GrpE protein; 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 rounds of ATP-dependent i [...]

hscB
Co-chaperone Hsc20; Co-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.
 
 
 0.870
Pnap_1568
FeS cluster assembly scaffold IscU; 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.

Pnap_2285
TIGRFAM: ferredoxin, 2Fe-2S type, ISC system; PFAM: ferredoxin; KEGG: pol:Bpro_2183 ferredoxin, 2Fe-2S type.

erpA2
Iron-sulfur cluster assembly accessory protein; Required for insertion of 4Fe-4S clusters.
