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

cca1tRNA-nucleotidyltransferase; Catalyzes the addition and repair of the essential 3'- terminal CCA sequence in tRNAs without using a nucleic acid template. Adds these three nucleotides in the order of C, C, and A to the tRNA nucleotide-73, using CTP and ATP as substrates and producing inorganic pyrophosphate. Also shows phosphatase, 2'-nucleotidase and 2',3'-cyclic phosphodiesterase activities. These phosphohydrolase activities are probably involved in the repair of the tRNA 3'-CCA terminus degraded by intracellular RNases. (412 aa)    
Predicted Functional Partners:
rtcB
rtcB protein, 57% identical(70% similairty) to TrEMBL;Q7NZ85 TrEMBL;Q8FCS7(56% identity). Has IPR001233;UPF0027(PF01139, Uncharacterized protein family):A number of uncharacterized proteins including Escherichia coli rtcB, Mycobacterium tuberculosis MtCY441.01., Caenorhabditis elegans F16A11.2 and Methanococcus jannaschii MJ0682 belong to this family. Has no Signal peptide or TMH present; High confidence in function and specificity.

birA
biotin--[acetyl-CoA-carboxylase] ligase; BirA bifunctional protein [Includes: Biotin operon repressor; Biotin--[acetyl-CoA-carboxylase] synthetase (EC 6.3.4.15) (Biotin--protein ligase)]. birA acts both as a biotin-operon repressor and as the enzyme that synthesizes the corepressor, acetyl-coa:carbon- dioxide ligase. this protein also activates biotin to form biotinyl-5'-adenylate and transfers the biotin moiety to biotin-accepting proteins. InterPro: Biotin--acetyl-CoA-carboxylase ligase birA_ligase: biotin--acetyl-CoA-carboxyla; Specificity unclear.

sspA1
Putative stringent starvation protein A. Homology to sspA of E. coli of 26% (sprot|SSPA_ECOLI). FORMS AN EQUIMOLAR COMPLEX WITH THE RNA POLYMERASE HOLOENZYME (RNAP) BUT NOT WITH THE CORE ENZYME. IT IS SYNTHESIZED PREDOMINANTLY WHEN CELLS ARE EXPOSED TO AMINO ACID STARVATION AT WHICH TIME IT ACCOUNTS FOR OVER 50% OF THE TOTAL PROTEIN SYNTHESIZED. InterPro: Glutathione S-transferase N terminus (IPR001045) Pfam: Glutathione S-transferase, N-terminal domaine no signal peptide no TMHs; Family membership.

metG
MetG protein; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation.
 
 
 
 0.762
dapB
DapB protein; Catalyzes the conversion of 4-hydroxy-tetrahydrodipicolinate (HTPA) to tetrahydrodipicolinate; Belongs to the DapB family.
  
    0.722
pnp
Polyribonucleotide nucleotidyltransferase; Involved in mRNA degradation. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3'- to 5'- direction.
 
 
 
 0.697
sspB
Putative stringent starvation protein B. Homology to sspB of E. coli of 38% (sprot|SSPB_ECOLI) Seems to act in concert with sspA in the regulation of several proteins during exponential and stationary-phase growth. The exact function of sspB is not yet known. Pfam: Stringent starvation protein B no signal peptide no TMHs.
  
     0.667
FtsI
Probable peptidoglycan glycosyltransferase; Catalyzes cross-linking of the peptidoglycan cell wall at the division septum; Belongs to the transpeptidase family. FtsI subfamily.
 
   
 0.640
azo0495
Putative NADH dehydrogenase; 33%; Specificity unclear.
  
    0.637
hfq
RNA-binding regulatory 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.
