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:
hfqHost factor I for bacteriophage Q beta replication; RNA chaperone that binds small regulatory RNA (sRNAs) and mRNAs to facilitate mRNA translational regulation in response to envelope stress, environmental stress and changes in metabolite concentrations. Also binds with high specificity to tRNAs (By similarity). Plays a central regulatory role in the microbial response to space flight conditions. Is essential for virulence and is required for efficient invasion of non-phagocytic cells. (102 aa)
tolBTol protein required for outer membrane integrity; Part of the Tol-Pal system, which plays a role in outer membrane invagination during cell division and is important for maintaining outer membrane integrity. TolB occupies a key intermediary position in the Tol-Pal system because it communicates directly with both membrane-embedded components, Pal in the outer membrane and TolA in the inner membrane. (430 aa)
deoBPhosphopentomutase; Phosphotransfer between the C1 and C5 carbon atoms of pentose; Belongs to the phosphopentomutase family. (407 aa)
trxBSimilar to E. coli thioredoxin reductase (AAC73974.1); Blastp hit to AAC73974.1 (321 aa), 96% identity in aa 1 - 320. (322 aa)
grxBGlutaredoxin 2; Similar to E. coli glutaredoxin 2 (AAC74148.1); Blastp hit to AAC74148.1 (215 aa), 85% identity in aa 1 - 215. (215 aa)
dadXAlanine racemase 2; Isomerizes L-alanine to D-alanine which is then oxidized to pyruvate by DadA. (356 aa)
STM2446Putative iron-dependent peroxidase; Similar to E. coli orf, hypothetical protein (AAC75484.1); Blastp hit to AAC75484.1 (308 aa), 94% identity in aa 10 - 308. (299 aa)
trxCSimilar to E. coli putative thioredoxin-like protein (AAC75635.1); Blastp hit to AAC75635.1 (139 aa), 94% identity in aa 1 - 139; Belongs to the thioredoxin family. (139 aa)
luxSQuorum sensing protein; Involved in the synthesis of autoinducer 2 (AI-2) which is secreted by bacteria and is used to communicate both the cell density and the metabolic potential of the environment. The regulation of gene expression in response to changes in cell density is called quorum sensing. Catalyzes the transformation of S-ribosylhomocysteine (RHC) to homocysteine (HC) and 4,5-dihydroxy-2,3-pentadione (DPD) (By similarity); Belongs to the LuxS family. (171 aa)
rpoSSigma S (sigma 38) factor of RNA polymerase; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the master transcriptional regulator of the stationary phase and the general stress response. (330 aa)
nlpDLipoprotein; Activator of the cell wall hydrolase AmiC. Required for septal murein cleavage and daughter cell separation during cell division (By similarity); Belongs to the E.coli NlpD/Haemophilus LppB family. (377 aa)
feoASimilar to E. coli ferrous iron transport protein A (AAC76433.1); Blastp hit to AAC76433.1 (75 aa), 96% identity in aa 1 - 75. (75 aa)
feoBFerrous iron transport protein B; Probable transporter for a GTP-driven Fe(2+) uptake system. Belongs to the TRAFAC class TrmE-Era-EngA-EngB-Septin-like GTPase superfamily. FeoB GTPase (TC 9.A.8) family. (772 aa)
grxCGlutaredoxin 3; Has a glutathione-disulfide oxidoreductase activity in the presence of NADPH and glutathione reductase. Reduces low molecular weight disulfides and proteins. (83 aa)
trxAThioredoxin 1; Participates in various redox reactions through the reversible oxidation of its active center dithiol to a disulfide and catalyzes dithiol-disulfide exchange reactions; Belongs to the thioredoxin family. (109 aa)
oxyRRegulatory protein sensor for oxidative stress; Regulates intracellular hydrogen peroxide (LysR family); similar to E. coli activator, hydrogen peroxide-inducible genes (AAC76943.1); Blastp hit to AAC76943.1 (305 aa), 95% identity in aa 1 - 305; Belongs to the LysR transcriptional regulatory family. (305 aa)
coaAPantothenate kinase. (SW:COAA_SALTY). (316 aa)
soxRRedox-sensing transcriptional activator SoxR; Activates the transcription of the soxS gene which itself controls the superoxide response regulon. SoxR contains a 2Fe-2S iron- sulfur cluster that may act as a redox sensor system that recognizes superoxide. The variable redox state of the Fe-S cluster is employed in vivo to modulate the transcriptional activity of SoxR in response to specific types of oxidative stress (By similarity). (152 aa)
mopAChaperone Hsp60 with peptide-dependent ATPase activity; Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions. (548 aa)
STM0402Similar to E. coli alkyl hydroperoxide reductase, C22 subunit; detoxification of hydroperoxides (AAC73706.1); Blastp hit to AAC73706.1 (187 aa), 36% identity in aa 1 - 186. (200 aa)
