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

ktrCPotassium uptake protein; Catalytic subunit of the KtrCD potassium uptake transporter. The 2 major potassium transporter complexes KtrAB and KtrCD confer resistance to both suddenly imposed and prolonged osmotic stress. (221 aa)
sigDRNA polymerase sigma-28 factor (sigma-D); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This alternative sigma factor is required for the transcription of the flagellin and motility genes as well as for wild- type chemotaxis. (254 aa)
ymdBPutative hydrolase involved in biofilm formation; Plays a central, regulatory role in the late adaptive responses and affects the levels of many genes. May act via regulation of cAMP levels. Decreases the expression of motility genes and induces genes involved in biofilm formation, by controlling the expression of SlrR. Required for formation of intercellular nanotubes that bridge neighboring cells to allow molecular exchange. Plays a key role in directing the early stages of colony development. In vitro, has a metal-dependent phosphodiesterase activity against 2',3'-cAMP and 2',3'-cGM [...] (264 aa)
ymcAMaster regulator for biofilm formation; May work together with YlbF to regulate community development. (143 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)
sinIAntagonist of SinR; Acts as an antagonist to SinR. SinI prevents SinR from binding to its target sequence on the gene for AprE. (57 aa)
sinRMaster regulator of biofilm formation; Negative as well as positive regulator of alternate developmental processes that are induced at the end of vegetative growth in response to nutrient depletion. Binds to the alkaline protease (aprE) gene at two sites. Also acts as a repressor of the key sporulation gene spo0A. Negatively regulates transcription of the eps operon, which is responsible for the biosynthesis of an exopolysaccharide involved in biofilm formation; therefore it could govern the transition between a state in which bacteria swim or swarm and a state in which bacteria assemb [...] (111 aa)
sipWType I signal peptidase; Required for the cleavage of the signal sequence of TasA and TapA, which are involved in biofilm formation. Belongs to the peptidase S26B family. (190 aa)
tapALipoprotein for biofilm formation; Required for biofilm formation. Required for the proper anchoring and polymerization of TasA amyloid fibers at the cell surface. Is also a minor component of TasA fibers. (253 aa)
yrdPPutative oxidoreductase; Involved in potassium and divalent cation transport. Enhances the transport activity of the cation/potassium transporter CzcD. (345 aa)
bslABiofilm hydrophobic layer component; Involved in biofilm formation. Self-polymerizes and forms a layer on the surface of biofilms that confers hydrophobicity to the biofilm. The layer is stable and capable of resistance to high mechanical force compression. Required for complex colony architecture.

hagFlagellin protein; Flagellin is the subunit which polymerizes to form the filaments of bacterial flagella. Assembly into flagella requires FliW. Acts as a homeostatic autoinhibitory regulator to control its own cytoplasmic levels. Partner switching by flagellin between FliW and CsrA provides a flagellar assembly checkpoint to tightly control the timing of flagellin synthesis. Flagellin binds to assembly factor FliW, freeing translation regulator CsrA to repress translation of the flagellin mRNA. When the flagellar hook is assembled flagellin is secreted, depleting intracellular flagell [...] (304 aa)
