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

gyrBDNA topoisomerase (ATP-hydrolysing); 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 [...] (829 aa)

parC
DNA topoisomerase IV subunit A; Topoisomerase IV is essential for chromosome segregation. It relaxes supercoiled DNA. Performs the decatenation events required during the replication of a circular DNA molecule; Belongs to the type II topoisomerase GyrA/ParC subunit family. ParC type 1 subfamily.

azo1795
Conserved hypothetical protein; DNA topoisomerase I (EC 5.99.1.2). The reaction catalyzed by topoisomerases leads to the conversion of one topological isomer of DNA to another. cbiB: cobalamin biosynthesis protein; Specificity unclear.

dnaN
DNA-directed DNA polymerase; 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 repl [...]

azo2973
Pentapeptide repeat family protein, 36% identity(46% similarity) to TrEMBL;Q88JH6. Signal P reporting Signal Peptide present. Has 3 copies of PF00805,Pentapeptide repeats;IPR001646, 5peptide_repeat;These repeats are found in many cyanobacterial proteins. The repeats were first identified in hglK The function of these repeats is unknown. The structure of this repeat has been predicted to be a beta-helix. The repeat can be approximately described as A(D/N)LXX, where X can be any amino acid; Conserved hypothetical protein.

yacG
Conserved hypothetical protein; Inhibits all the catalytic activities of DNA gyrase by preventing its interaction with DNA. Acts by binding directly to the C- terminal domain of GyrB, which probably disrupts DNA binding by the gyrase.
    
 
 0.825
rpoB
DNA-directed RNA polymerase; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
  
  
 0.738
secA
Preprotein translocase SecA subunit; Part of the Sec protein translocase complex. Interacts with the SecYEG preprotein conducting channel. Has a central role in coupling the hydrolysis of ATP to the transfer of proteins into and across the cell membrane, serving both as a receptor for the preprotein-SecB complex and as an ATP-driven molecular motor driving the stepwise translocation of polypeptide chains across the membrane. Belongs to the SecA family.

smc
Chromosome segregation protein; Required for chromosome condensation and partitioning. Belongs to the SMC family.
  
 
 0.705
recQ
ATP-dependent DNA helicase recQ (EC 3.6.1.-). INVOLVED IN THE RECF RECOMBINATION PATHWAY; ITS GENE EXPRESSION IS UNDER THE REGULATION OF THE SOS SYSTEM. IT IS A DNA HELICASE. recq: ATP-dependent DNA helicase RecQ; High confidence in function and specificity.
