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

EHA59105.1PFAM: DNA topoisomerase, type IIA, subunit A/C-terminal; DNA gyrase/topoisomerase IV, subunit A, C-terminal beta-pinwheel; KEGG: pmf:P9303_00041 DNA gyrase/topoisomerase IV, subunit A; SMART: DNA topoisomerase, type IIA, subunit A/C-terminal. (820 aa)    
Predicted Functional Partners:
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.

EHA64211.1
TIGRFAM: Peptidase S26A, signal peptidase I; KEGG: pmf:P9303_07511 signal peptidase I; PFAM: Peptidase S24/S26A/S26B, conserved region; Belongs to the peptidase S26 family.

queG
Iron-sulfur cluster binding protein; Catalyzes the conversion of epoxyqueuosine (oQ) to queuosine (Q), which is a hypermodified base found in the wobble positions of tRNA(Asp), tRNA(Asn), tRNA(His) and tRNA(Tyr); Belongs to the QueG family.

EHA59110.1
NusB antitermination factor; Involved in transcription antitermination. Required for transcription of ribosomal RNA (rRNA) genes. Binds specifically to the boxA antiterminator sequence of the ribosomal RNA (rrn) operons.

pheT
TIGRFAM: Phenylalanyl-tRNA synthetase, class IIc, beta subunit, bacterial; KEGG: pmf:P9303_14801 phenylalanyl-tRNA synthetase subunit beta; HAMAP: Phenylalanyl-tRNA synthetase, class IIc, beta subunit, bacterial.

EHA63025.1
TIGRFAM: Thioredoxin reductase; KEGG: pma:Pro1245 thioredoxin reductase; PFAM: FAD-dependent pyridine nucleotide-disulphide oxidoreductase; Thioredoxin domain.

topA
DNA topoisomerase I; Releases the supercoiling and torsional tension of DNA, which is introduced during the DNA replication and transcription, by transiently cleaving and rejoining one strand of the DNA duplex. Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA- (5'-phosphotyrosyl)-enzyme intermediate and the expulsion of a 3'-OH DNA strand. The free DNA strand then undergoes passage around the unbroken strand, thus removing DNA supe [...]

ftsZ
Cell division protein FtsZ; Essential cell division protein that forms a contractile ring structure (Z ring) at the future cell division site. The regulation of the ring assembly controls the timing and the location of cell division. One of the functions of the FtsZ ring is to recruit other cell division proteins to the septum to produce a new cell wall between the dividing cells. Binds GTP and shows GTPase activity.
  
 
 
 0.571
secA
Protein translocase subunit secA; 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 as an ATP-driven molecular motor driving the stepwise translocation of polypeptide chains across the membrane; Belongs to the SecA family.
