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

PF0027Putative integral membrane transport protein; Hydrolyzes RNA 2',3'-cyclic phosphodiester to an RNA 2'- phosphomonoester. In vitro, ligates 5' and 3' half-tRNA molecules with 2',3'-cyclic phosphate and 5'-hydroxyl termini, respectively, to the product containing the 2'-5' phosphodiester linkage. Ligase activity requires GTP, but GTP hydrolysis is not required for the reaction, which is reversible. Ligase activity is weak compared to the phosphodiesterase activity; Belongs to the 2H phosphoesterase superfamily. ThpR family. (184 aa)    
Predicted Functional Partners:
rtcB
Hypothetical protein; GTP-dependent RNA ligase that is involved in tRNA splicing and RNA repair. Joins RNA with 2',3'-cyclic-phosphate or 3'-phosphate ends to RNA with 5'-hydroxy ends; Belongs to the RtcB family.
 
   
 0.824
cca
tRNA nucleotidyltransferase (cca); 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.
 
     0.701
rtc
RNA-3'-phosphate cyclase; Catalyzes the GTP-dependent conversion of 3'-phosphate to a 2',3'-cyclic phosphodiester at the end of RNA. The biological role of this enzyme is unknown but it is likely to function in some aspects of cellular RNA processing; Belongs to the RNA 3'-terminal cyclase family. Type 1 subfamily.
 
  
 0.680
rnr
Ribonucleotide reductase; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides; Belongs to the ribonucleoside diphosphate reductase class-2 family.
 
     0.604
trpS
tryptophanyl-tRNA synthetase; Function Code: 13.1 Translation: Amino acyl tRNA synthetases; Belongs to the class-I aminoacyl-tRNA synthetase family.
 
   
 0.548
PF0265
2-amino-3-ketobutyrate CoA ligase (glycine acetyl transferase); Catalyzes the decarboxylative condensation of pimeloyl-[acyl- carrier protein] and L-alanine to produce 8-amino-7-oxononanoate (AON), [acyl-carrier protein], and carbon dioxide.
  
  
 0.486
PF0476
Competence-damage inducible protein, putative; Function Code: 16 Unknown:; Belongs to the CinA family.
     
 0.484
PF0462
CDP-diacylglycerol--glycerol-3-phosphate 3-phosphatidyltransferase; Function Code: 7.1 Fatty Acid and Phospholipid Metabolism: General; Belongs to the CDP-alcohol phosphatidyltransferase class-I family.
 
     0.445
PF0028
Putative acetyl transferase; Function Code: 16.0 Unknown.
     
 0.433
PF0031
Threonine synthase; Function Code: 1.3 Amino Acid Biosynthesis: Aspartate family.
       0.427
