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.

recFDNA replication and repair protein; 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. (397 aa)    
Predicted Functional Partners:
dnaN
DNA polymerase III, beta chain; Confers DNA tethering and processivity to DNA polymerases and other proteins. Acts as a clamp, forming a ring around DNA (a reaction catalyzed by the clamp-loading complex) which diffuses in an ATP- independent manner freely and bidirectionally along dsDNA. Initially characterized for its ability to contact the catalytic subunit of DNA polymerase III (Pol III), a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria; Pol III exhibits 3'-5' exonuclease proofreading activity. The beta chain is required for initiation of r [...]

gyrB
DNA gyrase subunit B; 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.

recR
Recombination protein; 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.
 
 
 0.909
DIP0004
Conserved hypothetical protein; Similar to Mycobacterium paratuberculosis hypothetical 17.5 kDa protein TR:Q9L7L4 (EMBL:AF222789) (166 aa) fasta scores: E(): 5.6e-18, 45.45% id in 143 aa.
  
  
 0.855
DIP0149
Conserved hypothetical protein (pseudogene); Pseudogene. Similar to the plasmid borne Corynebacterium striatum YtpG TR:Q9FB50 (EMBL:AF024666) (76 aa) fasta scores: E(): 3.2e-09, 78.46% id in 65 aa. Presents a frameshift at residue 50.
  
  
 0.768
rnpA
Conserved hypothetical protein (pseudogene); RNaseP catalyzes the removal of the 5'-leader sequence from pre-tRNA to produce the mature 5'-terminus. It can also cleave other RNA substrates such as 4.5S RNA. The protein component plays an auxiliary but essential role in vivo by binding to the 5'-leader sequence and broadening the substrate specificity of the ribozyme.
  
  
 0.729
polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity; Belongs to the DNA polymerase type-A family.
     
 0.727
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.

Negative supercoiling favors strand separation, and DNA replication, transcription, recombination and repair, all of which involve strand separation.

rpmH
50S ribosomal protein L34; Similar to Mycobacterium paratuberculosis 50S ribosomal protein L34 RpmH SW:RL34_MYCPA (Q9L7L8) (47 aa) fasta scores: E(): 2.9e-15, 80.85% id in 47 aa, to Streptomyces bikiniensis 50S ribosomal protein L34 RpmH SW:RL34_STRBI (P25820) (45 aa) fasta scores: E(): 2.2e-13, 81.39% id in 43 aa, and to Escherichia coli 50S ribosomal protein L34 Rpmh or SsaF or RimA or B3703 or Z5194 or ECS4638 or STM3839 SW:RL34_ECOLI (P02437) (46 aa) fasta scores: E(): 1.1e-07, 59.52% id in 42 aa; Belongs to the bacterial ribosomal protein bL34 family.
