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

lexAlexA repressor (lexA); 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. (209 aa)    
Predicted Functional Partners:
recA
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. Plays a central role in DNA metabolism, participating in general homologous recombination, recombinational (postreplication) DNA repair, and prophage induction; Belongs to the RecA family.

HI_1564
Predicted coding region HI1564; Hypothetical protein; identified by GeneMark; putative.
  
 
 0.696
recN
DNA repair protein (recN); May be involved in recombinational repair of damaged DNA.
   
  
 0.640
dapF
Diaminopimelate epimerase (dapF); Catalyzes the stereoinversion of LL-2,6-diaminoheptanedioate (L,L-DAP) to meso-diaminoheptanedioate (meso-DAP), a precursor of L- lysine and an essential component of the bacterial peptidoglycan. Only accepts DAP isomers with the L configuration ; Belongs to the diaminopimelate epimerase family.
  
  
 0.534
plsB
Glycerol-3-phosphate acyltransferase (plsB); Similar to SP:P00482 GB:K00127 PID:147295 PID:148102 PID:148109 percent identity: 57.21; identified by sequence similarity; putative; Belongs to the GPAT/DAPAT family.
     
 0.498
HI_1052
Transcriptional regulator, araC family, putative; Similar to SP:P35319 PID:581707 percent identity: 25.67; identified by sequence similarity; putative.
  
   0.475
uvrD
DNA helicase II (uvrD); May process damage occurring in non-replicating regions of DNA to produce recombinational intermediates for sister strand recombinational exchange.
     
 0.445
trpC
Indole-3-glycerol phosphate synthase / phosphoribosylanthranilate isomerase (trpC); Bifunctional enzyme that catalyzes two sequential steps of tryptophan biosynthetic pathway. The first reaction is catalyzed by the isomerase, coded by the TrpF domain; the second reaction is catalyzed by the synthase, coded by the TrpC domain (By similarity).
     
 0.435
yafQ
Conserved hypothetical protein; Toxic component of a type II toxin-antitoxin (TA) system. Its cognate antitoxin is RelB (By similarity).
