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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

yehTTranscriptional regulatory protein BtsR; Member of the two-component regulatory system BtsS/BtsR, which is part of a nutrient-sensing regulatory network composed of BtsS/BtsR, the low-affinity pyruvate signaling system YpdA/YpdB and their respective target proteins, YjiY and YhjX. Responds to depletion of nutrients, specifically serine, and the concomitant presence of extracellular pyruvate. BtsR regulates expression of yjiY by binding to its promoter region. Activation of the BtsS/BtsR signaling cascade also suppresses YpdA/YpdB-mediated yhjX induction (239 aa)    
Predicted Functional Partners:
yehU
Sensor histidine kinase BtsS; Member of the two-component regulatory system BtsS/BtsR, which is part of a nutrient-sensing regulatory network composed of BtsS/BtsR, the low-affinity pyruvate signaling system YpdA/YpdB and their respective target proteins, YjiY and YhjX. Responds to depletion of nutrients, specifically serine, and the concomitant presence of extracellular pyruvate. BtsS is a high-affinity receptor for extracellular pyruvate that activates BtsR by phosphorylation. Activation of the BtsS/BtsR signaling cascade also suppresses YpdA/YpdB-mediated yhjX induction

ypdA
Sensor histidine kinase YpdA; Member of the two-component regulatory system YpdA/YpdB, which is part of a nutrient-sensing regulatory network composed of YpdA/YpdB, the high-affinity pyruvate signaling system BtsS/BtsR and their respective target proteins, YhjX and YjiY. YpdA activates YpdB by phosphorylation in response to high concentrations of extracellular pyruvate. Activation of the YpdA/YpdB signaling cascade also promotes BtsS/BtsR-mediated yjiY expression

yhjX
Uncharacterized MFS-type transporter YhjX; Part of a nutrient-sensing regulatory network composed of the two-component regulatory systems BtsS/BtsR and YpdA/YpdB, and their respective target proteins, YjiY and YhjX; Belongs to the major facilitator superfamily
      
 0.862
yjiY
Inner membrane protein YjiY; Part of a nutrient-sensing regulatory network composed of the two-component regulatory systems BtsS/BtsR and YpdA/YpdB, and their respective target proteins, YjiY and YhjX; Belongs to the CstA family

mhpD
2-keto-4-pentenoate hydratase; Catalyzes the conversion of 2-hydroxypentadienoic acid (enolic form of 2-oxopent-4-enoate) to 4-hydroxy-2-ketopentanoic acid; Belongs to the hydratase/decarboxylase family. MhpD subfamily

barA
Signal transduction histidine-protein kinase BarA; Member of the two-component regulatory system UvrY/BarA involved in the regulation of carbon metabolism via the CsrA/CsrB regulatory system. Phosphorylates UvrY, probably via a four-step phosphorelay

crp
cAMP-activated global transcriptional regulator CRP; A global transcription regulator. Complexes with cyclic AMP (cAMP) which allosterically activates DNA binding (to consensus sequence 5'-AAATGTGATCTAGATCACATTT-3') to directly regulate the transcription of about 300 genes in about 200 operons and indirectly regulate the expression of about half the genome. There are 3 classes of CRP promoters; class I promoters have a single CRP-binding site upstream of the RNA polymerase (RNAP)- binding site, whereas in class II promoters the single CRP- and RNAP-binding site overlap, CRP making mult [...]
