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.

hrcAPutative heat-inducible transcription repressor; Negative regulator of class I heat shock genes (grpE-dnaK- dnaJ and groELS operons). Prevents heat-shock induction of these operons. (345 aa)    
Predicted Functional Partners:
grpE
Chaperone protein cofactor 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 rounds [...]

dnaJ2
Chaperone protein 2; 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, DnaK [...]

dnaG
DNA primase; RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication. Belongs to the DnaG primase family.
     
 0.822
clpX
Putative ATPase; ATP-dependent specificity component of the Clp protease. It directs the protease to specific substrates. Can perform chaperone functions in the absence of ClpP.
      
 0.814
lspA
Putative lipoprotein signal peptidase; This protein specifically catalyzes the removal of signal peptides from prolipoproteins; Belongs to the peptidase A8 family.
      
 0.777
hemN
Putative oxygen-independent coproporphyrinogen III oxidase; Probably acts as a heme chaperone, transferring heme to an unknown acceptor. Binds one molecule of heme per monomer, possibly covalently. Binds 1 [4Fe-4S] cluster. The cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine. Belongs to the anaerobic coproporphyrinogen-III oxidase family.
  
    0.775
dnaK
Chaperone protein DnaK; Acts as a chaperone; Belongs to the heat shock protein 70 family.
  
  
 0.770
hspR
Putative chaperone locus transcriptional regulator, HspR; Similar to Streptomyces coelicolor putative heat shock protein HspR or SCH44.08c SW:HSPR_STRCO (P40183) (151 aa) fasta scores: E(): 5.4e-16, 52.59% id in 135 aa, and to Mycobacterium tuberculosis HspR or Rv0353 or MTCY13E10.13 TR:O06302 (EMBL:Z95324) (126 aa) fasta scores: E(): 6.6e-23, 66.66% id in 117 aa.

DIP1723
Hypothetical protein; No significant database matches.
       0.752
DIP1719
Conserved hypothetical protein; Specifically methylates the N3 position of the uracil ring of uridine 1498 (m3U1498) in 16S rRNA. Acts on the fully assembled 30S ribosomal subunit.
