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.

perRFerric uptake regulator-like protein, putative; Manganese-dependent repressor that controls a regulon of oxidative stress resistance and iron-storage proteins. Regulates expression of genes encoding antioxidant proteins, such as katA, ahpCF, bcp and trxB. Also regulates expression of the iron-storage protein ftn, the ferritin-like protein mrgA, the ferric uptake regulator fur, the manganese transporter operon mntABC, and its own expression. May act as a hydrogen peroxide and organic hydroperoxide sensor. Required for full virulence in a murine skin abscess model of infection. (148 aa)    
Predicted Functional Partners:
ahpC
Alkyl hydroperoxide reductase; 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. Is important for survival under desiccation conditions. Not required for virulence although is necessary for nasal colonization.

ABD31055.1
Conserved hypothetical protein.
     
 0.773
ABD31054.1
Conserved hypothetical protein; Belongs to the D-isomer specific 2-hydroxyacid dehydrogenase family.
 
     0.748
ftnA
Ferritin, putative; Iron-storage protein; Belongs to the ferritin family. Prokaryotic subfamily.
     
 0.671
hemL2
Glutamate-1-semialdehyde-2,1-aminomutase, putative.
       0.612
trxA
Thioredoxin; Component of the thioredoxin-thioredoxin reductase system. Participates in various redox reactions through the reversible oxidation of its active center dithiol to a disulfide and catalyzes dithiol-disulfide exchange reactions (By similarity).
   
 
 0.583
spxA
Conserved hypothetical protein; Interferes with activator-stimulated transcription by interaction with the RNA polymerase alpha-CTD. May function to globally reduce transcription of genes involved in growth- and development- promoting processes and to increase transcription of genes involved in thiol homeostasis, during periods of extreme stress. Belongs to the ArsC family. Spx subfamily.
   
  
 0.565
ctsR
Conserved hypothetical protein; Negative regulator of clpC, clpB and clpP transcription by binding directly and specifically to their promoter region.
      
 0.562
sodA
Superoxide dismutase, Mn, putative; Destroys superoxide anion radicals which are normally produced within the cells and which are toxic to biological systems. May play a role in maintaining cell viability throughout all stages of growth, but may be the major SOD activity in the exponential growth- phase. Has a role in resisting external superoxide stress. Involved in acid tolerance and the acid-adaptive response. Mediates the derepression of perR regulon in the response to HOCl stress when the level of SOD activity is low.
   
  
 0.562
rpoA
DNA-directed RNA polymerase alpha chain, putative; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
