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:
pstAPhosphate ABC transporter (permease); Part of the binding-protein-dependent transport system YqgGHIJK. Probably responsible for the translocation of the substrate across the membrane (By similarity); Belongs to the binding-protein-dependent transport system permease family. CysTW subfamily. (294 aa)
phoDAlkaline phosphatase D; Evidence 1a: Function experimentally demonstrated in the studied strain; enzyme. (583 aa)
glpQAGlycerophosphoryl diester phosphodiesterase; Glycerophosphoryl diester phosphodiesterase hydrolyzes deacylated phospholipids to G3P and the corresponding alcohols. (293 aa)
codYTranscriptional regulator, GTP and BCAA-dependent; DNA-binding protein that represses the expression of many genes that are induced as cells make the transition from rapid exponential growth to stationary phase and sporulation. It is a GTP- binding protein that senses the intracellular GTP concentration as an indicator of nutritional limitations. At low GTP concentration it no longer binds GTP and stop to act as a transcriptional repressor. (259 aa)
resETwo-component sensor histidine kinase; Member of the two-component regulatory system ResD/ResE involved in the global regulation of aerobic and anaerobic respiration. Probably phosphorylates ResD. (589 aa)
amtBAmmonium transporter; Functions as an ammonium and methylammonium transporter in the absence of glutamine. Required for ammonium utilization at low concentrations or at low pH values, when ammonium is the single nitrogen source. Required for binding of NrgB to the membrane. Interaction between GlnK-AmtB complex and TnrA protects TnrA from proteolytic degradation. (404 aa)
sigLRNA polymerase sigma-54 factor (sigma-L); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is responsible for the expression of the levanase operon. The open complex (sigma-54 and core RNA polymerase) serves as the receptor for receipt of the melting signal from the remotely bound activator protein LevR for the expression of the levanase operon. (436 aa)
ccpATranscriptional regulator (Lacl family); Global transcriptional regulator of carbon catabolite repression (CCR) and carbon catabolite activation (CCA), which ensures optimal energy usage under diverse conditions. Interacts with either P- Ser-HPr or P-Ser-Crh, leading to the formation of a complex that binds to DNA at the catabolite-response elements (cre). Binding to DNA allows activation or repression of many different genes and operons. (334 aa)
phoPTwo-component response regulator; Member of the two-component regulatory system PhoP/PhoR involved in the regulation of alkaline phosphatase genes phoA and phoB and of phosphodiesterase. (240 aa)
phoRTwo-component sensor histidine kinase; Member of the two-component regulatory system PhoP/PhoR involved in the alkaline phosphatase genes regulation. PhoR may function as a membrane-associated protein kinase that phosphorylates PhoP in response to environmental signals. (579 aa)
phoAAlkaline phosphatase A; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the alkaline phosphatase family. (461 aa)
scoCHTH-type transcriptional regulator Hpr; Negative regulator of protease production and sporulation. Acts by binding directly to the promoter of protease genes (aprE and nprE), and by repressing oligopeptide permease operons (appABCDF and oppABCDF), thereby preventing uptake of oligopeptides required for initiation of sporulation. Acts with SinR as a corepressor of epr expression. (203 aa)
tnrANitrogen sensing transcriptional regulator; Transcription regulator that actives the transcription of genes required for nitrogen assimilation such as nrgAB (ammonium transport), nasABCDEF (nitrate/nitrite assimilation), ureABC (urea degradation) and gabP (GABA transport), during nitrogen limitation. Also represses glnRA and gltAB in the absence of ammonium. On the contrary of the MerR members, which require longer DNA sites for high-affinity binding, TnrA requires a DNA sequence of 17 nucleotides as minimal binding site. (110 aa)
ykoLHypothetical protein; Evidence 5: No homology to any previously reported sequences; PubMedId: 10671441. (60 aa)
ctaAheme-A synthase; Catalyzes the oxidation of the C8 methyl side group on heme O porphyrin ring into a formyl group. Also involved in the sporulation. (306 aa)
resDTwo-component response regulator; Member of the two-component regulatory system ResD/ResE. Required for the expression of resA, ctaA, qcrABC and fnr; activation role in global regulation of aerobic and anaerobic respiration. (240 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)
ahrCTranscriptional regulator; Represses the synthesis of biosynthetic enzymes and activates the arginine catabolism. Controls the transcription of the two operons rocABC and rocDEF. (149 aa)
nasDAssimilatory nitrite reductase subunit; Required for nitrite assimilation. (805 aa)
psiEPhosphate starvation inducible protein; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; membrane component. (138 aa)
rshGTP pyrophosphokinase (RelA/SpoT); In eubacteria ppGpp (guanosine 3'-diphosphate 5-' diphosphate) is a mediator of the stringent response that coordinates a variety of cellular activities in response to changes in nutritional abundance. This enzyme catalyzes the formation of pppGpp which is then hydrolyzed to form ppGpp, it is probably the hydrolysis activity that is required for optimal growth (Probable); Belongs to the RelA/SpoT family. (734 aa)
spo0BSporulation initiation phosphotransferase; Key element in the phosphorelay regulating sporulation initiation. Acts on spo0A. Mediates reversible phosphoryl transfer from spo0F to spo0A. (192 aa)
