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.

ccatRNA nucleotidyltransferase - 2',3'-cyclic phosphodiesterase - 2' nucleotidase and phosphatase; 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. (368 aa)    
Predicted Functional Partners:

Protein kinase; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Unknown function.
     
 0.854
htrG
Putative signal transduction protein; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative regulator.
 
  
 0.791
ycgB
Putative type IV piliation protein; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; cell process; Unknown function.
       0.785
PP_0396
Homologs of previously reported genes of unknown function; Unknown function; Belongs to the UPF0229 family.
       0.783
apaH
Bis(5'-nucleosyl)-tetraphosphatase, symmetrical; Hydrolyzes diadenosine 5',5'''-P1,P4-tetraphosphate to yield ADP; Belongs to the Ap4A hydrolase family.
 
  
 0.760
metG
Methionine--tRNA ligase; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation.
 
 
 0.760
sspB
ClpXP protease specificity-enhancing factor; Function of homologous gene experimentally demonstrated in an other organism; factor; Cellularprocesses : Adaptations to atypical conditions.
  
     0.752
dapB
4-hydroxy-tetrahydrodipicolinate reductase; Catalyzes the conversion of 4-hydroxy-tetrahydrodipicolinate (HTPA) to tetrahydrodipicolinate.
  
  
 0.740
lptD
LPS-assembly protein LptD; Together with LptE, is involved in the assembly of lipopolysaccharide (LPS) at the surface of the outer membrane.
 
    0.716
birA
Bifunctional biotin-[acetyl-CoA-carboxylase] ligase/biotin operon repressor BirA; 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.
