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:
some 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

Predicted Functional Partners:
fabR
Binds the promoter region of at least fabA and fabB, but probably not yqfA . Represses the transcription of fabA and fabB, involved in unsaturated fatty acid (UFA) biosynthesis . By controlling UFA production, FabR directly influences the physical properties of the membrane bilayer. ECO:0000269|PubMed:11859088, ECO:0000269|PubMed:19854834,

seqA
Negative regulator of replication initiation, which contributes to regulation of DNA replication and ensures that replication initiation occurs exactly once per chromosome per cell cycle. Binds to pairs of hemimethylated GATC sequences in the oriC region, thus preventing assembly of replication proteins and re- initiation at newly replicated origins. Repression is relieved when the region becomes fully methylated. Can also bind to hemimethylated GATC sequences outside of oriC region. Binds, with less affinity, to fully methylated GATC sites and affects timing of replication. May play a [...]

nlpI
May be involved in cell division. May play a role in bacterial septation or regulation of cell wall degradation during cell division. Negatively controls the production of extracellular DNA (eDNA)
  
     0.769
yejL
Belongs to the UPF0352 family
  
     0.765
fadR
Multifunctional regulator of fatty acid metabolism (PubMed:1569108, PubMed:8446033, PubMed:9388199, PubMed:11859088, PubMed:19854834, PubMed:21276098). Represses transcription of at least eight genes required for fatty acid transport and beta-oxidation including fadA, fadB, fadD, fadL and fadE . Activates transcription of at least three genes required for unsaturated fatty acid biosynthesis: fabA, fabB and iclR, the gene encoding the transcriptional regulator of the aceBAK operon encoding the glyoxylate shunt enzymes .

    0.744
metJ
This regulatory protein, when combined with SAM (S- adenosylmethionine) represses the expression of the methionine regulon and of enzymes involved in SAM synthesis. It is also autoregulated
  
     0.739
yifE
Belongs to the UPF0438 family
  
     0.737
mutH
Sequence-specific endonuclease that cleaves unmethylated GATC sequences. It is involved in DNA mismatch repair
  
     0.715
rraB
Globally modulates RNA abundance by binding to RNase E (Rne) and regulating its endonucleolytic activity. Can modulate Rne action in a substrate-dependent manner by altering the composition of the degradosome
  
     0.714
matP
Required for spatial organization of the terminus region of the chromosome (Ter macrodomain) during the cell cycle. Prevents early segregation of duplicated Ter macrodomains during cell division. Binds specifically to matS, which is a 13 bp signature motif repeated within the Ter macrodomain
