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
Your Input:
sigXRNA polymerase ECF(extracytoplasmic function)-type sigma factor sigma(X); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. May be involved in the regulation of iron metabolism; Belongs to the sigma-70 factor family. ECF subfamily. (194 aa)
spo0AResponse regulator; May play the central regulatory role in sporulation. It may be an element of the effector pathway responsible for the activation of sporulation genes in response to nutritional stress. Spo0A may act in concert with Spo0H (a sigma factor) to control the expression of some genes that are critical to the sporulation process. Repressor of abrB, activator of the spoIIa operon. Binds the DNA sequence 5'-TGNCGAA-3' (0A box). (267 aa)
sinRMaster regulator of biofilm formation; Negative as well as positive regulator of alternate developmental processes that are induced at the end of vegetative growth in response to nutrient depletion. Binds to the alkaline protease (aprE) gene at two sites. Also acts as a repressor of the key sporulation gene spo0A. Negatively regulates transcription of the eps operon, which is responsible for the biosynthesis of an exopolysaccharide involved in biofilm formation; therefore it could govern the transition between a state in which bacteria swim or swarm and a state in which bacteria assemb [...] (111 aa)
dnaJCo-factor of molecular chaperone; 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 betwe [...] (375 aa)
dnaKMolecular chaperone; Acts as a chaperone; Belongs to the heat shock protein 70 family. (611 aa)
rarADNA-dependent ATPase; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type e: enzyme; Belongs to the AAA ATPase family. RarA/MGS1/WRNIP1 subfamily. (421 aa)
clpXProtein unfolding ATPase required for presentation of proteins to proteases; ATP-dependent specificity component of the Clp protease. It directs the protease to specific substrates. Can perform chaperone functions in the absence of ClpP (By similarity). Probably the major protease that degrades proteins tagged by trans-translation. (420 aa)
uppPUndecaprenyl-diphosphatase; Catalyzes the dephosphorylation of undecaprenyl diphosphate (UPP). Confers resistance to bacitracin; Belongs to the UppP family. (276 aa)
sufBFeS cluster formation protein; The SufBCD complex acts synergistically with SufE to stimulate the cysteine desulfurase activity of SufS. The SufBCD complex contributes to the assembly or repair of oxygen-labile iron-sulfur clusters under oxidative stress. May facilitate iron uptake from extracellular iron chelators under iron limitation (By similarity). Belongs to the UPF0051 (ycf24) family. (465 aa)
sufDFeS assembly protein SufD; The SufBCD complex acts synergistically with SufE to stimulate the cysteine desulfurase activity of SufS. The SufBCD complex contributes to the assembly or repair of oxygen-labile iron-sulfur clusters under oxidative stress. May facilitate iron uptake from extracellular iron chelators under iron limitation (By similarity). Belongs to the UPF0051 (ycf24) family. (437 aa)
clpCClass III stress response-related ATPase, AAA+ superfamily; Competence gene repressor; required for cell growth at high temperature. Negative regulator of comK expression. May interact with MecA to negatively regulate comK; Belongs to the ClpA/ClpB family. ClpC subfamily. (810 aa)
sufCSulfur mobilizing ABC protein, ATPase; Evidence 2b: Function of strongly homologous gene; enzyme; Belongs to the ABC transporter superfamily. Ycf16 family. (261 aa)
clpPATP-dependent Clp protease proteolytic subunit; Cleaves peptides in various proteins in a process that requires ATP hydrolysis. Has a limited peptidase activity in the absence of ATP-binding subunits ClpC, ClpE or ClpX. Has a chymotrypsin-like activity. Plays a major role in the degradation of misfolded proteins (By similarity). ClpXP is involved in the complete degradation of the site-2 clipped anti-sigma-W factor RsiW. This results in the release of SigW and the transcriptional activation of genes under the control of the sigma-W factor. Probably the major protease that degrades prot [...] (197 aa)
clpEATP-dependent Clp protease (class III stress gene); ATPase essential both for efficient CtsR-dependent gene derepression during heat stress and for rerepression. Together with ClpP, degrades the global regulator CtsR after heat shock. Is also involved in disaggregation of heat-denatured proteins. Has thus a role in overall protein quality control in response to heat stress. (699 aa)
mecAAdaptor protein controlling oligomerization of the AAA+ protein ClpC; Enables the recognition and targeting of unfolded and aggregated proteins to the ClpC protease or to other proteins involved in proteolysis. Acts negatively in the development of competence by binding ComK and recruiting it to the ClpCP protease. When overexpressed, inhibits sporulation. Also involved in Spx degradation by ClpC. (218 aa)
sspBSmall acid-soluble spore protein (beta-type SASP); SASP are bound to spore DNA. They are double-stranded DNA- binding proteins that cause DNA to change to an a-like conformation. They protect the DNA backbone from chemical and enzymatic cleavage and are thus involved in dormant spore's high resistance to UV light. (67 aa)
groELChaperonin large subunit; Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions. (544 aa)
