STRINGSTRING
lexA protein (Dermacoccus nishinomiyaensis) - STRING interaction network
"lexA" - LexA repressor in Dermacoccus nishinomiyaensis
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

lexALexA repressor; Represses a number of genes involved in the response to DNA damage (SOS response), including recA and lexA. In the presence of single-stranded DNA, RecA interacts with LexA causing an autocatalytic cleavage which disrupts the DNA-binding part of LexA, leading to derepression of the SOS regulon and eventually DNA repair (238 aa)    
Predicted Functional Partners:
recA
Protein RecA; Can catalyze the hydrolysis of ATP in the presence of single-stranded DNA, the ATP-dependent uptake of single-stranded DNA by duplex DNA, and the ATP-dependent hybridization of homologous single-stranded DNAs. It interacts with LexA causing its activation and leading to its autocatalytic cleavage (364 aa)
   
 
  0.816
polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5’-3’ exonuclease activity (889 aa)
     
   
  0.712
HX89_06140
Endonuclease; Derived by automated computational analysis using gene prediction method- Protein Homology (608 aa)
   
   
  0.688
topA
DNA topoisomerase 1; Releases the supercoiling and torsional tension of DNA, which is introduced during the DNA replication and transcription, by transiently cleaving and rejoining one strand of the DNA duplex. Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA-(5’-phosphotyrosyl)-enzyme intermediate and the expulsion of a 3’-OH DNA strand. The free DNA strand then undergoes passage around the unbroken strand, thus removing DNA super [...] (940 aa)
         
  0.676
HX89_08525
DNA repair protein RecN; May be involved in recombinational repair of damaged DNA (583 aa)
     
 
  0.654
sigA
RNA polymerase sigma factor SigA; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the primary sigma factor during exponential growth (550 aa)
   
 
 
  0.652
hrcA
Heat-inducible transcription repressor HrcA; Negative regulator of class I heat shock genes (grpE- dnaK-dnaJ and groELS operons). Prevents heat-shock induction of these operons (340 aa)
   
     
  0.651
recO
DNA repair protein RecO; Involved in DNA repair and RecF pathway recombination (269 aa)
 
   
  0.619
recR
Recombination protein RecR; May play a role in DNA repair. It seems to be involved in an RecBC-independent recombinational process of DNA repair. It may act with RecF and RecO (199 aa)
   
 
 
  0.615
argR
Arginine repressor; Regulates arginine biosynthesis genes (193 aa)
   
     
  0.611
