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

yacGConserved 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. (73 aa)    
Predicted Functional Partners:
zapD
Conserved hypothetical protein; Cell division factor that enhances FtsZ-ring assembly. Directly interacts with FtsZ and promotes bundling of FtsZ protofilaments, with a reduction in FtsZ GTPase activity.
       0.812
gyrA
DNA gyrase, A subunit; 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.
    
 
 0.805
parE
DNA topoisomerase IV, B subunit; 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 family. ParE type 1 subfamily.
    
 
 0.603
coaE
dephospho-CoA kinase; Catalyzes the phosphorylation of the 3'-hydroxyl group of dephosphocoenzyme A to form coenzyme A; Belongs to the CoaE family.
  
    0.603
gyrB
DNA gyrase, B subunit; 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.
    
 
 0.603
pilD
Leader peptidase PilD; Cleaves type-4 fimbrial leader sequence and methylates the N- terminal (generally Phe) residue.
       0.592
pilB
Type IV pilus assembly protein PilB; Identified by similarity to SP:P22608; match to protein family HMM PF00437; match to protein family HMM PF05157; match to protein family HMM TIGR02538.
       0.544
parC
DNA topoisomerase IV, A subunit; 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.
    
 
 0.543
pilC
Type IV pilin biogenesis protein PilC; Identified by similarity to GP:151066; match to protein family HMM PF00482.
       0.528
MCA2098
Putative DNA polymerase III, chi subunit; Identified by similarity to SP:P28905; match to protein family HMM PF04364.
