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:
hhaModulator of gene expression, with H-NS; Down-regulates hemolysin (hly) expression in complex with H- NS. Stimulates transposition events in vivo. Modifies the set of genes regulated by H-NS; Hha and Cnu (YdgT) increase the number of genes DNA bound by H-NS/StpA and may also modulate the oligomerization of the H-NS/StpA-complex. Binds DNA and influences DNA topology in response to environmental stimuli; does not however interact with DNA in the absence of H-NS. Involved in persister cell formation, acting downstream of mRNA interferase (toxin) MqsR. Decreases biofilm formation by repre [...] (72 aa)
ybgSPutative homeobox protein. (126 aa)
csgDcsgBAC operon transcriptional regulator; The master regulator for adhesive curli fimbriae expression; necessary for transcription of the csgBAC/ymdA operon. Plays a positive role in biofilm formation. May have the capability to respond to starvation and/or high cell density by activating csgBA transcription. Low-level constitutive expression confers an adherent curli fimbriae- expressing phenotype, up-regulates 10 genes and down-regulates 14 others. (216 aa)
bluRRepressor of blue light-responsive genes; Controls the expression of several small proteins that may play a role in biofilm maturation. Binds to and represses the operator of the ycgZ-ymgA-ariR-ymgC operon and also regulates ynaK. Binding is antagonized by BluF upon blue light (470 nm) irradiation. Blue light may increase the affinity of BluF for BluR, allowing it to be released from its operator. (243 aa)
bluFAnti-repressor for YcgE, blue light-responsive; Binds to and releases the BluR repressor from its bound DNA target in a blue light-dependent (470 nm) fashion. A shift to low temperature also triggers a BluF-mediated relief of repression by BluR, suggesting BluF may serve as a thermometer. Blue light may act to increase the affinity of BluF for BluR, allowing it to be released from its operator. The protein has a reversible photocycle, and undergoes structural changes, probably in the EAL domain, in response to light. (403 aa)
ymgARcsB connector protein for regulation of biofilm; Probably a connector protein for RcsB/C regulation of biofilm formation, providing additional signal input into the two-component signaling pathway. May serve to stimulate biofilm maturation, probably via the Rcs phosphorelay. Mild overexpression at 16 degrees Celsius increases the production of colanic acid, an exopolysaccharide and matrix component, and reduces adhesive curli fimbriae expression. Both of these effects require RcsB. (90 aa)
ariRRcsB connector protein for regulation of biofilm and acid-resistance; Probably a connector protein for RcsB/C regulation of biofilm and acid-resistance, providing additional signal input into the two- component signaling pathway. May serve to stimulate biofilm maturation, via the Rcs phosphorelay. Regulates expression of genes involved in acid-resistance and biofilm formation, including the RcsB/C two- component system. May be a non-specific DNA-binding protein that binds genes and/or intergenic regions via a geometric recognition. Also confers resistance to H(2)O(2). Overexpression at [...] (88 aa)
ymgCBlue light, low temperature and stress induced protein. (82 aa)
gmrcyclic-di-GMP phosphodiesterase; Part of a signaling cascade that regulates curli biosynthesis. The cascade is composed of two cyclic-di-GMP (c-di-GMP) control modules, in which c-di-GMP controlled by the DgcE/PdeH pair (module I) regulates the activity of the DgcM/PdeR pair (module II), which in turn regulates activity of the transcription factor MlrA and expression of the master biofilm regulator csgD. PdeR acts as a trigger enzyme that connects modules I and II. It inhibits DgcM and MlrA by direct interaction. Inhibition is relieved when PdeR binds and degrades c-di-GMP generated by [...] (661 aa)
bdmBiofilm-dependent modulation protein. (71 aa)
mlrATranscriptional activator of csgD and csgBA; Activates transcription of csgD, the master regulator of biofilm formation, by binding to its promoter region. Also controls the transcription of cadC and ibaG. Part of a signaling cascade that regulates curli biosynthesis. The cascade is composed of two c-di-GMP control modules, in which c-di-GMP controlled by the DgcE/PdeH pair (module I) regulates the activity of the DgcM/PdeR pair (module II), which in turn regulates activity of the transcription factor MlrA. (243 aa)
rcsBResponse regulator in two-component regulatory system with RcsC and YojN; Component of the Rcs signaling system, which controls transcription of numerous genes. RcsB is the response regulator that binds to regulatory DNA regions. Can function both in an RcsA-dependent or RcsA-independent manner. The system regulates expression of numerous genes, including genes involved in colanic acid capsule synthesis, biofilm formation, cell division and outer membrane proteins synthesis. Also involved, with GadE, in control of glutamate-dependent acid resistance, and, with BglJ, in derepression of [...] (216 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)
gudPPutative D-glucarate transporter; Uptake of D-glucarate; Belongs to the major facilitator superfamily. Phthalate permease family. (450 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)
