STRINGSTRING
STRING protein interaction network
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

prpC
Phosphorylated protein phosphatase; Protein phosphatase that dephosphorylates PrkC and EF-G (elongation factor G, fusA). prpC and prkC are cotranscribed, which suggests that they form a functional couple in vivo, PrpC's primary role being possibly to counter the action of PrkC. May be involved in sporulation and biofilm formation. Does not seem to be involved in stress response. Dephosphorylates phosphorylated CgsA, EF-Tu and YezB.

rsbT
Switch protein/serine-threonine kinase; Provides the crucial link between the upstream module (communication of environmental stress) and the downstream module (integration of the environmental signals with signals of energy stress) that compose the signal transduction pathway controlling the sigma-B factor. Phosphorylates and inactivates its specific antagonist protein RsbS thanks to its serine kinase activity. Upon phosphorylation of RsbS, RsbT is released to stimulate RsbU, a PP2C phosphatase, thereby initiating the signaling cascade that ultimately activates sigma-B. The activity o [...]

ptkA
Protein tyrosine kinase; May be involved in the regulation of capsular polysaccharide biosynthesis. Autophosphorylates in vitro. Phosphorylates and activates in vitro two UDP-glucose dehydrogenases, YwqF and TuaD, as well as the DNA-binding proteins Ssb and SsbB; Belongs to the CpsD/CapB family.
    
 
 0.837
prkC
Protein kinase; Protein kinase that is responsible for triggering spore germination in response to muropeptides, signaling bacteria to exit dormancy. PrkC is thus a germination receptor that binds peptidoglycan fragments containing m-Dpm (meso-diaminopimelate), which act as spore germinants. Autophosphorylates and phosphorylates EF-G (elongation factor G, fusA); the latter modification is likely necessary for germination in response to peptidoglycan. Another group did not detect phosphorylation of EF-G. PrkC is a substrate in vitro of the cotranscribed phosphatase PrpC, which suggests [...]

spoIIAB
Anti-sigma factor (antagonist of sigma(F)) and serine kinase; Binds to sigma F and blocks its ability to form an RNA polymerase holoenzyme (E-sigma F). Phosphorylates SpoIIAA on a serine residue. This phosphorylation may enable SpoIIAA to act as an anti- anti-sigma factor that counteracts SpoIIAB and thus releases sigma F from inhibition.
    
 
 0.710
spo0M
Sporulation-control gene; Controls the expression of spo0A and is required to pass the morphological stage 0 of sporulation; Belongs to the spo0M family.
  
    0.706
ymfM
Conserved hypothetical protein with ACT domain; Evidence 7: Gene remnant.
     
 0.700
rsbW
Switch protein/serine kinase and anti-sigma factor (inhibitory sigma-B binding protein); Negative regulator of sigma-B activity. Phosphorylates and inactivates its specific antagonist protein, RsbV. Upon phosphorylation of RsbV, RsbW is released and binds to sigma-B, thereby blocking its ability to form an RNA polymerase holoenzyme (E-sigma-B).
    
 
 0.668
yfkJ
Protein-tyrosine-phosphatase; Dephosphorylates the phosphotyrosine-containing proteins. Involved in ethanol stress resistance.
