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

Score
pcnBpolyA polymerase; Adds poly(A) tail to the 3' end of many RNAs, which usually targets these RNAs for decay. Plays a significant role in the global control of gene expression, through influencing the rate of transcript degradation, and in the general RNA quality control. Belongs to the tRNA nucleotidyltransferase/poly(A) polymerase family. (474 aa)    
Predicted Functional Partners:
folK2
2-amino-4-hydroxy-6- hydroxymethyldihydropteridine pyrophosphokinase; Identified by match to protein family HMM PF01288; match to protein family HMM TIGR01498.
 
  
 0.977
pnp
Polyribonucleotide nucleotidyltransferase; Involved in mRNA degradation. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3'- to 5'- direction.
 
 
 0.807
hfq
Host factor-I protein; RNA chaperone that binds small regulatory RNA (sRNAs) and mRNAs to facilitate mRNA translational regulation in response to envelope stress, environmental stress and changes in metabolite concentrations. Also binds with high specificity to tRNAs. Belongs to the Hfq family.
    
 
 0.754
dapB
Dihydrodipicolinate reductase; Catalyzes the conversion of 4-hydroxy-tetrahydrodipicolinate (HTPA) to tetrahydrodipicolinate.
 
    0.747
dnaA
Chromosomal replication initiator protein DnaA; Plays an important role in the initiation and regulation of chromosomal replication. Binds to the origin of replication; it binds specifically double-stranded DNA at a 9 bp consensus (dnaA box): 5'- TTATC[CA]A[CA]A-3'. DnaA binds to ATP and to acidic phospholipids.
   
 
 0.732
birA
birA bifunctional protein; Acts both as a biotin--[acetyl-CoA-carboxylase] ligase and a biotin-operon repressor. In the presence of ATP, BirA activates biotin to form the BirA-biotinyl-5'-adenylate (BirA-bio-5'-AMP or holoBirA) complex. HoloBirA can either transfer the biotinyl moiety to the biotin carboxyl carrier protein (BCCP) subunit of acetyl-CoA carboxylase, or bind to the biotin operator site and inhibit transcription of the operon.
 
  
 0.698
plsC
1-acyl-sn-glycerol-3-phosphate acyltransferase; Identified by similarity to SP:P26647; match to protein family HMM PF01553; match to protein family HMM TIGR00530; Belongs to the 1-acyl-sn-glycerol-3-phosphate acyltransferase family.
     
 0.689
panB
3-methyl-2-oxobutanoate hydroxymethyltransferase; Catalyzes the reversible reaction in which hydroxymethyl group from 5,10-methylenetetrahydrofolate is transferred onto alpha- ketoisovalerate to form ketopantoate; Belongs to the PanB family.
  
  
 0.642
metG
methionyl-tRNA synthetase, beta subunit; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation.
 
 
 0.622
sspB
Identified by similarity to SP:P25663; match to protein family HMM PF04386.
  
     0.616
