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:
glnGDNA-binding transcriptional regulator NtrC; Member of the two-component regulatory system NtrB/NtrC, which controls expression of the nitrogen-regulated (ntr) genes in response to nitrogen limitation. Phosphorylated NtrC binds directly to DNA and stimulates the formation of open promoter-sigma54-RNA polymerase complexes. Activates transcription of many genes and operons whose products minimize the slowing of growth under nitrogen-limiting conditions, including genes coding for glutamine synthetase (glnA), transporters, amino acid permeases and catabolic enzymes. (469 aa)
glnAGlutamine synthetase; Catalyzes the ATP-dependent biosynthesis of glutamine from glutamate and ammonia. (469 aa)
groLCpn60 chaperonin GroEL, large subunit of GroESL; Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions. (548 aa)
lexATranscriptional repressor of SOS regulon; Represses a number of genes involved in the response to DNA damage (SOS response), including recA and lexA. Binds to the 16 bp palindromic sequence 5'-CTGTATATATATACAG-3'. In the presence of single- stranded DNA, RecA interacts with LexA causing an autocatalytic cleavage which disrupts the DNA-binding part of LexA, leading to derepression of the SOS regulon and eventually DNA repair. Implicated in hydroxy radical-mediated cell death induced by hydroxyurea treatment .The SOS response controls an apoptotic-like death (ALD) induced (in the absence [...] (202 aa)
glpFGlycerol facilitator; Transporter of glycerol across the cytoplasmic membrane, with limited permeability to water and small uncharged compounds such as polyols; Belongs to the MIP/aquaporin (TC 1.A.8) family. (281 aa)
perRCP4-6 prophage; Apparent regulatory gene involved in peroxide resistance in stationary phase; Belongs to the LysR transcriptional regulatory family. (297 aa)
amtBAmmonium transporter; Involved in the uptake of ammonia; Belongs to the ammonia transporter channel (TC 1.A.11.2) family. (428 aa)
kdpEResponse regulator in two-component regulatory system with KdpD; Member of the two-component regulatory system KdpD/KdpE involved in the regulation of the kdp operon. (225 aa)
narXSensory histidine kinase in two-component regulatory system with NarL; Acts as a sensor for nitrate/nitrite and transduces signal of nitrate availability to the NarL protein and of both nitrate/nitrite to the NarP protein. NarX probably activates NarL and NarP by phosphorylation in the presence of nitrate. NarX also plays a negative role in controlling NarL activity, probably through dephosphorylation in the absence of nitrate. (598 aa)
narKNitrate/nitrite transporter; Catalyzes nitrate uptake, nitrite uptake and nitrite export across the cytoplasmic membrane. Functions as a nitrate/nitrite exchanger, and protons are probably not co-transported with the substrate. (463 aa)
glnBRegulatory protein P-II for glutamine synthetase; P-II indirectly controls the transcription of the glutamine synthetase gene (glnA). P-II prevents NR-II-catalyzed conversion of NR- I to NR-I-phosphate, the transcriptional activator of GlnA. When P-II is uridylylated to P-II-UMP, these events are reversed. When the ratio of Gln to 2-ketoglutarate decreases, P-II is uridylylated to P-II-UMP, which causes the deadenylation of glutamine synthetase by GlnE, so activating the enzyme; Belongs to the P(II) protein family. (112 aa)
fhlAFormate hydrogenlyase transcriptional activator; Required for induction of expression of the formate dehydrogenase H and hydrogenase-3 structural genes. Also activates expression of hyf operon (encodes the silent hydrogenase-4 gene cluster). (692 aa)
glnLSensory histidine kinase in two-component regulatory system with GlnG; Member of the two-component regulatory system NtrB/NtrC, which controls expression of the nitrogen-regulated (ntr) genes in response to nitrogen limitation. Under conditions of nitrogen limitation, NtrB autophosphorylates and transfers the phosphoryl group to NtrC. In the presence of nitrogen, acts as a phosphatase that dephosphorylates and inactivates NtrC. (349 aa)
