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

gyrADNA 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. (815 aa)

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.

metG
Methionyl-tRNA synthetase; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation.
 
  
 0.852
hisS
PFAM: Anticodon binding domain; tRNA synthetase class II core domain (G, H, P, S and T); TIGRFAM: histidyl-tRNA synthetase; COGs: COG0124 Histidyl-tRNA synthetase; HAMAP: Histidyl-tRNA synthetase, class IIa, subgroup; InterPro IPR002314:IPR004154:IPR015807; KEGG: mem:Memar_1585 histidyl-tRNA synthetase; PFAM: Aminoacyl-tRNA synthetase, class II (G/ H/ P/ S), conserved region; Anticodon-binding; SPTR: Histidyl-tRNA synthetase; TIGRFAM: Histidyl-tRNA synthetase, class IIa, subgroup; Belongs to the class-II aminoacyl-tRNA synthetase family.

dnaK
Chaperone protein dnaK; Acts as a chaperone.
 
 
 
 0.840
ileS
Isoleucyl-tRNA synthetase; Catalyzes the attachment of isoleucine to tRNA(Ile). As IleRS can inadvertently accommodate and process structurally similar amino acids such as valine, to avoid such errors it has two additional distinct tRNA(Ile)-dependent editing activities. One activity is designated as 'pretransfer' editing and involves the hydrolysis of activated Val-AMP. The other activity is designated 'posttransfer' editing and involves deacylation of mischarged Val-tRNA(Ile). Belongs to the class-I aminoacyl-tRNA synthetase family. IleS type 2 subfamily.
 
  
 0.785
alaS
alanyl-tRNA synthetase; Catalyzes the attachment of alanine to tRNA(Ala) in a two- step reaction: alanine is first activated by ATP to form Ala-AMP and then transferred to the acceptor end of tRNA(Ala). Also edits incorrectly charged Ser-tRNA(Ala) and Gly-tRNA(Ala) via its editing domain.

EJG06094.1
TIGRFAM: signal peptidase I, archaeal type; InterPro IPR001733; KEGG: mem:Memar_0046 peptidase S26B, signal peptidase; SPTR: Peptidase S26B, signal peptidase; TIGRFAM: Peptidase S26B, eukaryotic signal peptidase.

rps9
PFAM: Ribosomal protein S9/S16; TIGRFAM: archaeal ribosomal protein S9P; COGs: COG0103 Ribosomal protein S9; InterPro IPR000754:IPR019958; KEGG: mpi:Mpet_0754 30S ribosomal protein S9P; PFAM: Ribosomal protein S9; SPTR: 30S ribosomal protein S9P; TIGRFAM: Ribosomal protein S9, archaeal; Belongs to the universal ribosomal protein uS9 family.

fusA
Translation elongation factor aEF-2; Catalyzes the GTP-dependent ribosomal translocation step during translation elongation. During this step, the ribosome changes from the pre-translocational (PRE) to the post-translocational (POST) state as the newly formed A-site-bound peptidyl-tRNA and P-site-bound deacylated tRNA move to the P and E sites, respectively. Catalyzes the coordinated movement of the two tRNA molecules, the mRNA and conformational changes in the ribosome; Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. EF-G/EF [...]
 
  
 0.764
serS
Seryl-tRNA synthetase; Catalyzes the attachment of serine to tRNA(Ser). Is also able to aminoacylate tRNA(Sec) with serine, to form the misacylated tRNA L- seryl-tRNA(Sec), which will be further converted into selenocysteinyl- tRNA(Sec).
