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

dnaJ1Chaperone protein cofactor 1; 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 D [...] (390 aa)    
Predicted Functional Partners:
dnaK
Chaperone protein DnaK; Acts as a chaperone; Belongs to the heat shock protein 70 family.
 0.999
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 [...]

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.

groEL2
Chaperonin GroEL2; Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions.
 
 0.926
groEL1
60 kDa chaperonin 1; Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions.
 
 0.908
groES
10 kDa chaperonin; Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter.

DIP2160
Modular polyketide synthase; Similar to Streptomyces verticillus polyketide synthase BlmVIII (bleomycin biosynthesis) TR:Q9FB25 (EMBL:AF210249) (1841 aa) fasta scores: E(): 1.3e-72, 27.240% id in 1931 aa, and to Streptomyces noursei nystatin biosynthesis polyketide synthase Nys TR:Q9L4W3 (EMBL:AF263912) (11096 aa) fasta scores: E(): 4e-71, 33.107% id in 882 aa, and to Amycolatopsis mediterranei rifamycin polyketide synthase TR:Q9F847 (EMBL:AF262754) (1265 aa) fasta scores: E(): 7.7e-61, 31.042% id in 902 aa.

clpB2
Putative heat shock protein (partial); Similar to Corynebacterium glutamicum ClpB protein SWALL:CLPB_CORGL (SWALL:P53532) (852 aa) fasta scores: E(): 0.027, 44.44% id in 99 aa, and to Mycobacterium leprae heat shock protein ClpB or ML2490 SWALL:Q9CB26 (EMBL:AL583925) (848 aa) fasta scores: E(): 0.66, 35.41% id in 96 aa. Note: Similar also to the C-terminal part of DIP2104 (849 aa) E(): 7.2e-08; 53.465% identity in 101 aa overlap.

clpB
Putative ATP-dependent protease regulatory subunit, ClpB; Part of a stress-induced multi-chaperone system, it is involved in the recovery of the cell from heat-induced damage, in cooperation with DnaK, DnaJ and GrpE. Acts before DnaK, in the processing of protein aggregates. Protein binding stimulates the ATPase activity; ATP hydrolysis unfolds the denatured protein aggregates, which probably helps expose new hydrophobic binding sites on the surface of ClpB-bound aggregates, contributing to the solubilization and refolding of denatured protein aggregates by DnaK (By similarity).

hrcA
Putative 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.
