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

DIP1180Putative cytotoxin/hemolysin; Similar to Mycobacterium tuberculosis CDC1551 cytotoxin/hemolysin MT1733 SWALL:AAK46002 (EMBL:AE007035) (268 aa) fasta scores: E(): 2.2e-53, 56.56% id in 274 aa, and to Caulobacter crescentus hemolysin A CC1324 SWALL:Q9A8M9 (EMBL:AE005808) (243 aa) fasta scores: E(): 1.2e-29, 42.27% id in 246 aa. (273 aa)    
Predicted Functional Partners:
ppnK
Inorganic polyphosphate/ATP-NAD kinase; Involved in the regulation of the intracellular balance of NAD and NADP, and is a key enzyme in the biosynthesis of NADP. Catalyzes specifically the phosphorylation on 2'-hydroxyl of the adenosine moiety of NAD to yield NADP.
  
  
 0.976
gyrA
DNA gyrase subunit A; 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.
  
  
 0.804
rsmG
Conserved hypothetical protein; Specifically methylates the N7 position of guanine in position 518 of 16S rRNA; Belongs to the methyltransferase superfamily. RNA methyltransferase RsmG family.
  
   
 0.774
DIP1840
Hypothetical protein; Poor database matches. C-terminus is similar to the C-terminal regions of Streptomyces coelicolor putative nicotinamidase SCE19A.18 TR:Q9S2G3 (EMBL:AL096852) (195 aa) fasta scores: E(): 6.4e-06, 33.33% id in 105 aa, and Mycobacterium avium pyrazinamidase/nicotinamidase PncA TR:P94914 (EMBL:U80820) (187 aa) fasta scores: E(): 2.8e-05, 36% id in 125 aa.
     
 0.770
DIP1178
Conserved hypothetical protein; Similar to Mycobacterium tuberculosis CDC1551 conserved hypothetical protein MT1731 SWALL:AAK46000 (EMBL:AE007035) (353 aa) fasta scores: E(): 1e-33, 41.06% id in 302 aa, and to Streptomyces coelicolor hypothetical 35.2 kDa protein SCI51.28c SWALL:Q9S212 (EMBL:AL109848) (343 aa) fasta scores: E(): 4e-32, 39.4% id in 302 aa.
     
 0.748
gyrB
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.

recN
DNA repair protein; May be involved in recombinational repair of damaged DNA.
 
  
 0.724
DIP1177
Conserved hypothetical protein; C-terminal region similar to Mycobacterium tuberculosis CDC1551 conserved hypothetical protein MT1730 SWALL:AAK45999 (EMBL:AE007035) (250 aa) fasta scores: E(): 4e-32, 47.73% id in 243 aa, and to Streptomyces coelicolor hypothetical 22.8 kDa protein SCI51.30c SWALL:Q9S210 (EMBL:AL109848) (210 aa) fasta scores: E(): 3.1e-24, 49.17% id in 181 aa.

Hypothetical protein; Doubtful CDS. No strong consensus RBS usptream. No significant database matches.
       0.636
rpoB
DNA-directed RNA polymerase beta chain; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
