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:
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)
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)
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)
comPTwo-component sensor histidine kinase; Sensor in the two-component regulatory system ComP/ComA involved in a major quorum response pathway that regulates the development of genetic competence. Plays a role in sporulation, at least partly interchangeable with that of SpoIIJ. Probably activates ComA by phosphorylation. (769 aa)
degQPleiotropic regulator; Stimulates the phosphotransfer from phospho-DegS to DegU. Affects protease and levansucrose production. (46 aa)
sdpAExport of killing factor; Required for the maturation of SdpC to SDP. Not required for SdpC signal peptide cleavage, secretion from the cell or disulfide bond formation. (158 aa)
epsAModulator of protein tyrosine kinase EpsB; Evidence 2b: Function of strongly homologous gene; regulator. (234 aa)
skfBSynthesis of sporulation killing factor A; Catalyzes the formation of the thioether bond required for production of the sporulation killing factor (SKF) from SkfA. Forms the cysteine-methionine thioether bond found in SKF; the acceptor amino acid can be hydrophobic, aromatic or a small hydrophilic amino acid but not a larger hydrophilic amino acid, i.e. Met=Ala, Phe, Leu, Tyr>Asn, Ser>>Gln, Glu, Lys. The relative position of Cys and Met in the substrate cannot be inverted, in vitro the thioether bond cannot be made in the absence of the SkfA propeptide, suggesting this is the first rea [...] (410 aa)
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)
spo0FTwo-component response regulator; Key element in the phosphorelay regulating sporulation initiation. Phosphorylation of spo0B during sporulation initiation. (124 aa)
sigHRNA polymerase sigma-30 factor (sigma(H)); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is involved in the transition to post- exponential phase in the beginning of sporulation. It is also required for transcription of several stationary phase genes. (218 aa)
abrBTranscriptional regulator for transition state genes; Ambiactive repressor and activator of the transcription of genes expressed during the transition state between vegetative growth and the onset of stationary phase and sporulation. It controls the expression of genes spovG and tycA. AbrB binds to the tycA promoter region at two A- and T-rich sites, it may be the sole repressor of tycA transcription; To B.subtilis Abh and SpoVT. (96 aa)
slrRTranscriptional regulator of autolysin genes; Represses sigma(D)-dependent flagellar genes and activate the eps and yqxM operons. Repressor activity is regulated by SlrA. Controls the initiation of biofilm formation. (152 aa)
srfAASurfactin synthetase; This protein is a multifunctional enzyme able to activate and polymerize the amino acids Leu, Glu, Asp and Val. Activation sites for these AA consist of individual domains. (3587 aa)
rapCResponse regulator aspartate phosphatase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the RAP family. (382 aa)
rapIResponse regulator aspartate phosphatase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type r: regulator; Belongs to the RAP family. (391 aa)
sspBSmall acid-soluble spore protein (beta-type SASP); SASP are bound to spore DNA. They are double-stranded DNA- binding proteins that cause DNA to change to an a-like conformation. They protect the DNA backbone from chemical and enzymatic cleavage and are thus involved in dormant spore's high resistance to UV light. (67 aa)
oppDOligopeptide ABC transporter (ATP-binding protein); Part of the binding protein-dependent transport system for oligopeptides. Probably responsible for energy coupling to the transport system. Required for sporulation and competence. (358 aa)
