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:
glnEFused deadenylyltransferase/adenylyltransferase for glutamine synthetase; Involved in the regulation of glutamine synthetase GlnA, a key enzyme in the process to assimilate ammonia. When cellular nitrogen levels are high, the C-terminal adenylyl transferase inactivates GlnA by covalent transfer of an adenylyl group from ATP to 'Tyr-398' of GlnA, thus reducing its activity. Conversely, when nitrogen levels are low, the N- terminal adenylyl removase (AR) activates GlnA by removing the adenylyl group by phosphorolysis, increasing its activity. The regulatory region of GlnE binds the signa [...] (946 aa)
yhiMInner membrane protein YhiM; Pseudogene, DUF4049 family protein. (350 aa)
yhiNPutative oxidoreductase; To H.influenzae HI_0933. (400 aa)
slpOuter membrane lipoprotein; The induction of Slp may help to stabilize the outer membrane during carbon starvation and stationary phase. (188 aa)
dctRPutative LuxR family repressor for dicarboxylate transport; May act as a transcriptional regulator of dctA. (176 aa)
hdeAStress response protein acid-resistance protein; Required for optimal acid stress protection. Exhibits a chaperone-like activity only at pH below 3 by suppressing non- specifically the aggregation of denaturated periplasmic proteins. Important for survival of enteric bacteria in the acidic environment of the host stomach. Also promotes the solubilization at neutral pH of proteins that had aggregated in their presence at acidic pHs. May cooperate with other periplasmic chaperones such as DegP and SurA. (110 aa)
hdeDAcid-resistance membrane protein. (190 aa)
gadEGad regulon transcriptional activator; Regulates the expression of several genes involved in acid resistance. Required for the expression of gadA and gadBC, among others, regardless of media or growth conditions. Binds directly to the 20 bp GAD box found in the control regions of both loci. (175 aa)
gadWTranscriptional activator of gadA and gadBC; Depending on the conditions (growth phase and medium), acts as a positive or negative regulator of gadA and gadBC. Repression occurs directly or via the repression of the expression of gadX. Activation occurs directly by the binding of GadW to the gadA and gadBC promoters. (242 aa)
gadXAcid resistance regulon transcriptional activator; Positively regulates the expression of about fifteen genes involved in acid resistance such as gadA, gadB and gadC. Depending on the conditions (growth phase and medium), can repress gadW. (274 aa)
gadAGlutamate decarboxylase A, PLP-dependent; Converts glutamate to gamma-aminobutyrate (GABA), consuming one intracellular proton in the reaction. The gad system helps to maintain a near-neutral intracellular pH when cells are exposed to extremely acidic conditions. The ability to survive transit through the acidic conditions of the stomach is essential for successful colonization of the mammalian host by commensal and pathogenic bacteria. (466 aa)
yhiDPutative Mg(2+) transport ATPase, inner membrane protein; Could be involved in magnesium uptake. (215 aa)
araCAra regulon transcriptional activator; Transcription factor that regulates the expression of several genes involved in the transport and metabolism of L-arabinose. Functions both as a positive and a negative regulator. In the presence of arabinose, activates the expression of the araBAD, araE, araFGH and araJ promoters. In the absence of arabinose, negatively regulates the araBAD operon. Represses its own transcription. Acts by binding directly to DNA. (292 aa)
glsAPutative glutaminase; Protein involved in cellular amino acid catabolic process. (310 aa)
gadCGlutamate:gamma-aminobutyric acid antiporter; Involved in glutamate-dependent acid resistance. Imports glutamate inside the cell while simultaneously exporting to the periplasm the GABA produced by GadA and GadB. The gad system helps to maintain a near-neutral intracellular pH when cells are exposed to extremely acidic conditions. The ability to survive transit through the acidic conditions of the stomach is essential for successful colonization of the mammalian host by commensal and pathogenic bacteria; Belongs to the amino acid-polyamine-organocation (APC) superfamily. Glutamate:GABA [...] (511 aa)
gadBGlutamate decarboxylase B, PLP-dependent; Converts glutamate to gamma-aminobutyrate (GABA), consuming one intracellular proton in the reaction. The gad system helps to maintain a near-neutral intracellular pH when cells are exposed to extremely acidic conditions. The ability to survive transit through the acidic conditions of the stomach is essential for successful colonization of the mammalian host by commensal and pathogenic bacteria; Belongs to the group II decarboxylase family. (466 aa)
ydeOUV-inducible global regulator, EvgA-, GadE-dependent; Induces the expression of gadE and mdtEF. Could also regulate the expression of other genes involved in acid resistance. (253 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)
