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

Peptidase; Derived by automated computational analysis using gene prediction method: Protein Homology.
       0.787
AMQ93197.1
Hypothetical protein; Catalyzes the strictly specific dephosphorylation of 2'- deoxyribonucleoside 5'-monophosphates.
       0.762
cmk
Cytidylate kinase; Derived by automated computational analysis using gene prediction method: Protein Homology.
      0.734
fabR
GntR family transcriptional regulator; Derived by automated computational analysis using gene prediction method: Protein Homology.
      
 0.631
argR
Arginine repressor; Regulates arginine biosynthesis genes.
      
 0.627
trpR
Transcriptional regulator; This protein is an aporepressor. When complexed with L- tryptophan it binds the operator region of the trp operon and prevents the initiation of transcription.
      
 0.598
nusB
N utilization substance protein B; 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.
 
  
 0.539
AMQ93192.1
Glycine cleavage system transcriptional activator; activates the gcvTHP operon in the presence of glycine and represses the operon in its absence; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the LysR transcriptional regulatory family.
     
 0.509
rlmM
rRNA methyltransferase; Catalyzes the 2'-O-methylation at nucleotide C2498 in 23S rRNA; Belongs to the class I-like SAM-binding methyltransferase superfamily. RNA methyltransferase RlmE family. RlmM subfamily.
       0.506
