STRINGSTRING
lexA protein (Acidaminococcus intestini) - STRING interaction network
"lexA" - SOS-response transcriptional repressor in Acidaminococcus intestini
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

lexASOS-response transcriptional 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 (195 aa)    
Predicted Functional Partners:
recA
recA protein; 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 (354 aa)

dinB
DNA-directed DNA polymerase; Poorly processive, error-prone DNA polymerase involved in untargeted mutagenesis. Copies undamaged DNA at stalled replication forks, which arise in vivo from mismatched or misaligned primer ends. These misaligned primers can be extended by PolIV. Exhibits no 3’-5’ exonuclease (proofreading) activity. May be involved in translesional synthesis, in conjunction with the beta clamp from PolIII (397 aa)
   
 
  0.851
gyrA
Type IIA topoisomerase; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to modulate DNA topology and maintain chromosomes in an underwound state. Negative supercoiling favors strand separation, and DNA replication, transcription, recombination and repair, all of which involve strand separation. Also able to catalyze the interconversion of other topological isomers of dsDNA rings, including catenanes and knotted rings. Type II topoisomerases break and join 2 DNA strands simultaneously in an ATP-dependent manner (842 aa)

Acin_2290
Pyruvate-flavodoxin oxidoreductase; Oxidoreductase required for the transfer of electrons from pyruvate to flavodoxin (1167 aa)
         
  0.756
Acin_2032
Pyruvate-ferredoxin oxidoreductase; Oxidoreductase required for the transfer of electrons from pyruvate to flavodoxin (1178 aa)
         
  0.756
Acin_1089
Hypothetical protein; Oxidoreductase required for the transfer of electrons from pyruvate to flavodoxin (1168 aa)
         
  0.756
Acin_0057
Pyruvate ferredoxin oxidoreductase; Oxidoreductase required for the transfer of electrons from pyruvate to flavodoxin (1134 aa)
         
  0.756
recF
Recombination protein F; The RecF protein is involved in DNA metabolism; it is required for DNA replication and normal SOS inducibility. RecF binds preferentially to single-stranded, linear DNA. It also seems to bind ATP (382 aa)
   
     
  0.746
dnaA
Chromosomal replication initiator protein; Plays an important role in the initiation and regulation of chromosomal replication. Binds to the origin of replication; it binds specifically double-stranded DNA at a 9 bp consensus (dnaA box)- 5’-TTATC[CA]A[CA]A-3’. DnaA binds to ATP and to acidic phospholipids (458 aa)
