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

STY1336DNA topoisomerase I, omega protein 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 [...] (865 aa)    
Predicted Functional Partners:

DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity; Belongs to the DNA polymerase type-A family.
 
 0.939
recQ
Similar to Escherichia coli ATP-dependent DNA helicase RecQ SW:RECQ_ECOLI (P15043; P76762) (607 aa) fasta scores: E(): 0, 94.6% id in 608 aa.

STY3510
Similar to Escherichia coli glutamate synthase [NADPH] large chain precursor GltB SW:GLTB_ECOLI (P09831) (1517 aa) fasta scores: E(): 0, 95.4% id in 1486 aa and to Pseudomonas aeruginosa glutamate synthase large subunit GltB TR:P95456 (EMBL:U81261) (1482 aa) fasta scores: E(): 0, 60.9% id in 1476 aa.

ssb
Single-strand DNA-binding protein; Plays an important role in DNA replication, recombination and repair. Binds to ssDNA and to an array of partner proteins to recruit them to their sites of action during DNA metabolism.
  
 
 0.899
ssB
Previously sequenced Salmonella typhi single strand binding protein ssB TR:Q9RHF4 (EMBL:AF000001) (178 aa) fasta scores: E(): 0, 100.0% id in 178 aa. Also highly similar to other single-stranded DNA-binding proteins including: Escherichia coli SW:SSB_ECOLI () (177 aa) fasta scores: E(): 0, 71.8% id in 177 aa and Bacteriophage P1 single-stranded DNA-binding protein Ssb-p1 ssb-p1 TR:Q9XJG4 (EMBL:AF125376) (162 aa) fasta scores: E(): 0, 67.7% id in 164 aa.
  
 
 0.899
STY3943
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.

STY1772
phenylalanyl-tRNA synthetase beta chain; Orthologue of E. coli pheT (SYFB_ECOLI); Fasta hit to SYFB_ECOLI (795 aa), 92% identity in 795 aa overlap; Belongs to the phenylalanyl-tRNA synthetase beta subunit family. Type 1 subfamily.

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.
