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:
hchAProtein/nucleic acid deglycase 1; Protein and nucleotide deglycase that catalyzes the deglycation of the Maillard adducts formed between amino groups of proteins or nucleotides and reactive carbonyl groups of glyoxals. Thus, functions as a protein deglycase that repairs methylglyoxal- and glyoxal-glycated proteins, and releases repaired proteins and lactate or glycolate, respectively. Deglycates cysteine, arginine and lysine residues in proteins, and thus reactivates these proteins by reversing glycation by glyoxals. Is able to repair glycated serum albumin, aspartate aminotransferase, [...] (283 aa)
tktBTransketolase 2, thiamine triphosphate-binding; Catalyzes the reversible transfer of a two-carbon ketol group from sedoheptulose-7-phosphate to glyceraldehyde-3-phosphate, producing xylulose-5-phosphate and ribose-5-phosphate. Catalyzes the transfer of a two-carbon ketol group from a ketose donor to an aldose acceptor, via a covalent intermediate with the cofactor thiamine pyrophosphate (By similarity). (667 aa)
ygaUUncharacterized protein; Highly specific potassium binding protein that is required for normal growth in the presence of high levels of external K(+). May act as a sensor of cytoplasmic K(+) concentration. Binds a single K(+) ion, which induces a large conformational change. Can also bind the larger alkali metal ions Rb(+) and Cs(+), and NH(4)(+). May be involved in the regulation of peptidoglycan cross-linking. (149 aa)
rpoSRNA polymerase, sigma S (sigma 38) factor; 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. Controls, positively or negatively, the expression of several hundred genes, which are mainly involved in metabolism, transport, regulation and stress management. (330 aa)
yhbOStress-resistance protein; Protein and nucleotide deglycase that catalyzes the deglycation of the Maillard adducts formed between amino groups of proteins or nucleotides and reactive carbonyl groups of glyoxals. Thus, functions as a protein deglycase that repairs methylglyoxal- and glyoxal-glycated proteins, and releases repaired proteins and lactate or glycolate, respectively. Deglycates cysteine, arginine and lysine residues in proteins, and thus reactivates these proteins by reversing glycation by glyoxals. Is able to repair glycated serum albumin, collagen, glyceraldehyde-3-phospha [...] (172 aa)
infBTranslation initiation factor IF-2; One of the essential components for the initiation of protein synthesis. May protect N-formylmethionyl-tRNA(fMet) from spontaneous hydrolysis. Promotes N-formylmethionyl-tRNA(fMet) binding to the 30S pre-initiation complex (PIC). Also involved in the hydrolysis of GTP during the formation of the 70S ribosomal complex. Upon addition of the 50S ribosomal subunit, IF-1, IF-2 and IF-3 are released leaving the mature 70S translation initiation complex. Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase fam [...] (890 aa)
treFCytoplasmic trehalase; Hydrolyzes trehalose to glucose. Could be involved, in cells returning to low osmolarity conditions, in the utilization of the accumulated cytoplasmic trehalose, which was synthesized in response to high osmolarity; Belongs to the glycosyl hydrolase 37 family. (549 aa)
metLBifunctional aspartokinase/homoserine dehydrogenase 2; Aspartokinase II and homoserine dehydrogenase II; Protein involved in methionine biosynthetic process and homoserine biosynthetic process. (810 aa)
oxyROxidative and nitrosative stress transcriptional regulator; Hydrogen peroxide sensor. Activates the expression of a regulon of hydrogen peroxide-inducible genes such as katG, gor, ahpC, ahpF, oxyS (a regulatory RNA), dps, fur and grxA. OxyR expression is negatively autoregulated by binding to a 43 bp region upstream of its own coding sequence. OxyR is inactivated by reduction of its essential disulfide bond by the product of GrxA, itself positively regulated by OxyR. Has also a positive regulatory effect on the production of surface proteins that control the colony morphology and auto- [...] (305 aa)
acnAAconitate hydratase 1; Catalyzes the reversible isomerization of citrate to isocitrate via cis-aconitate. The apo form of AcnA functions as a RNA- binding regulatory protein which plays a role as a maintenance or survival enzyme during nutritional or oxidative stress. During oxidative stress inactive AcnA apo-enzyme without iron sulfur clusters binds the acnA mRNA 3' UTRs (untranslated regions), stabilizes acnA mRNA and increases AcnA synthesis, thus mediating a post- transcriptional positive autoregulatory switch. AcnA also enhances the stability of the sodA transcript. (891 aa)
osmYSalt-inducible putative ABC transporter periplasmic binding protein; Hyperosmotically inducible periplasmic protein; Protein involved in response to osmotic stress. (201 aa)
poxBPyruvate dehydrogenase, thiamine triphosphate-binding, FAD-binding; Pyruvate oxidase; Protein involved in carbohydrate catabolic process and pyruvate catabolic process; Belongs to the TPP enzyme family. (572 aa)
yceIPeriplasmic high pH-inducible lipid-binding protein. (191 aa)
yciEPutative rubrerythrin/ferritin-like metal-binding protein. (168 aa)
yciFPutative structural proteins. (166 aa)
yjbJStress-induced protein, UPF0337 family; Belongs to the UPF0337 (CsbD) family. (69 aa)
pspARegulatory protein for phage-shock-protein operon; The phage shock protein (psp) operon (pspABCDE) may play a significant role in the competition for survival under nutrient- or energy-limited conditions. PspA negatively regulates expression of the pspABCDE promoter and of pspG through negative regulation of the psp- specific transcriptional activator PspF. Is also required for membrane integrity, efficient translocation and maintenance of the proton motive force. Belongs to the PspA/IM30 family. (222 aa)
osmCLipoyl-dependent Cys-based peroxidase, hydroperoxide resistance; Preferentially metabolizes organic hydroperoxides over inorganic hydrogen peroxide; Belongs to the OsmC/Ohr family. (143 aa)

katECatalase HPII, heme d-containing; Decomposes hydrogen peroxide into water and oxygen; serves to protect cells from the toxic effects of hydrogen peroxide. (753 aa)
otsBTrehalose-6-phosphate phosphatase, biosynthetic; Removes the phosphate from trehalose 6-phosphate (Tre6P) to produce free trehalose. Also catalyzes the dephosphorylation of glucose-6-phosphate (Glu6P) and 2-deoxyglucose-6-phosphate (2dGlu6P). (266 aa)
