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

zurTranscriptional regulator (Fur family); Acts as a negative controlling element, employing Zn(2+) as a cofactor to bind the operator of the repressed genes. Required for the zinc-specific repression of two operons implicated in zinc uptake, yciC and ycdHIyceA. Also represses the expression of rpmE2, the gene for ribosomal protein L31B, which is expressed only after the end of exponential growth. (145 aa)    
Predicted Functional Partners:
mntC
Manganese ABC transporter (permease); Probably part of the ABC transporter complex MntABCD involved in manganese import. Probably responsible for the translocation of the substrate across the membrane; Belongs to the ABC-3 integral membrane protein family.
  
  
 0.822
zinT
Zinc metallochaperone with NTPase activity; May bind GTP. Might act as metal chaperone (Potential). Contributes to optimal growth under starvation for zinc.
     
 0.786
yrpE
Putative lipoprotein; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type lp: lipoprotein; Belongs to the calycin superfamily. ZinT family.
     
 0.693
mntR
Transcriptional regulator (DtxR family); Central regulator of manganese homeostasis that regulates the expression of both manganese uptake and efflux systems. In the presence of high levels of manganese, it mediates repression of the manganese uptake systems MntH and MntABCD and activation of the efflux systems MneP and MneS. Binds with high affinity to the regulatory regions of its target genes. The manganese concentration required for activation of efflux is higher than that for repression of uptake ; Belongs to the DtxR/MntR family.
  
  
 0.616
rpoA
RNA polymerase (alpha subunit); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
   
   0.608
znuC
Zn(II) transporter (ATP-binding protein); Part of the high-affinity ABC transporter complex ZnuABC involved in zinc import (Probable). Responsible for energy coupling to the transport system (By similarity). ZnuABC-mediated zinc transport is required for comF expression and competence development.
  
  
 0.572
birA
Biotin acetyl-CoA-carboxylase ligase and biotin regulon repressor; Acts both as a biotin--[acetyl-CoA-carboxylase] ligase and a repressor; Belongs to the biotin--protein ligase family.
     
 0.552
ahpC
Alkyl hydroperoxide reductase (small subunit); Thiol-specific peroxidase that catalyzes the reduction of hydrogen peroxide and organic hydroperoxides to water and alcohols, respectively. Plays a role in cell protection against oxidative stress by detoxifying peroxides; Belongs to the peroxiredoxin family. AhpC/Prx1 subfamily.
  
  
 0.530
ykuU
Putative 2-cys peroxiredoxin; Thiol-specific peroxidase that catalyzes the reduction of hydrogen peroxide and organic hydroperoxides to water and alcohols, respectively. Plays a role in cell protection against oxidative stress by detoxifying peroxides.
  
  
 0.526
yqfU
Putative integral inner membrane protein; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pm: putative membrane component.
