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
ccatRNA nucleotidyltransferase (CCA-adding enzyme); 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. (456 aa)    
Predicted Functional Partners:
Msm_0054
2'-5' RNA ligase, LigT; Hydrolyzes RNA 2',3'-cyclic phosphodiester to an RNA 2'- phosphomonoester; Belongs to the 2H phosphoesterase superfamily. ThpR family.
 
     0.900
aroB
Predicted alternative 3-dehydroquinate synthase; Catalyzes the oxidative deamination and cyclization of 2- amino-3,7-dideoxy-D-threo-hept-6-ulosonic acid (ADH) to yield 3- dehydroquinate (DHQ), which is fed into the canonical shikimic pathway of aromatic amino acid biosynthesis; Belongs to the archaeal-type DHQ synthase family.
       0.878
Msm_0729
Molybdopterin biosynthesis protein, MoeB; COG0476.
  
 
 0.874
aroA
Fructose-1,6-bisphosphate aldolase; Catalyzes a transaldol reaction between 6-deoxy-5- ketofructose 1-phosphate (DKFP) and L-aspartate semialdehyde (ASA) with an elimination of hydroxypyruvaldehyde phosphate to yield 2-amino-3,7- dideoxy-D-threo-hept-6-ulosonate (ADH). Plays a key role in an alternative pathway of the biosynthesis of 3-dehydroquinate (DHQ), which is involved in the canonical pathway for the biosynthesis of aromatic amino acids.
       0.786
nac
Transcription factor, NACalpha-BTF3 related; Contacts the emerging nascent chain on the ribosome. Belongs to the NAC-alpha family.
 
     0.737
spt5
Transcription antiterminator, NusG; Stimulates transcription elongation; Belongs to the archaeal Spt5 family.
  
     0.688
Msm_1375
Predicted RNA-binding protein; COG1491.
 
   
 0.638
dnaG
DNA primase (type), DnaG; RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication. Also part of the exosome, which is a complex involved in RNA degradation. Acts as a poly(A)-binding protein that enhances the interaction between heteropolymeric, adenine-rich transcripts and the exosome.
 
   
 0.637
Msm_0217
tRNA intron endonuclease, EndA; COG1676.
