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
pyrGCTP synthase; Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as the source of nitrogen. Regulates intracellular CTP levels through interactions with the four ribonucleotide triphosphates. (551 aa)    
Predicted Functional Partners:
guaA-2
GMP synthase; Catalyzes the synthesis of GMP from XMP.
  
 
 0.945
ndk
Nucleoside diphosphate kinase (NDK); Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate; Belongs to the NDK family.
  
 
 0.935
rplF
50S ribosomal protein L6; This protein binds to the 23S rRNA, and is important in its secondary structure. It is located near the subunit interface in the base of the L7/L12 stalk, and near the tRNA binding site of the peptidyltransferase center; Belongs to the universal ribosomal protein uL6 family.
   
 
 0.929
dcd
Deoxycytidine triphosphate deaminase; Catalyzes the deamination of dCTP to dUTP.
  
 
 0.924
RB2978
Probable MutT-family protein; PMID: 8843436 best DB hits: BLAST: embl:CAC16440.1; (AL450165) putative MutT-family protein; E=2e-05 swissprot:P56380; AP4A_MOUSE BIS(5'-NUCLEOSYL)-TETRAPHOSPHATASE; E=5e-05 pir:F75532; MutTnudix family protein - Deinococcus radiodurans; E=3e-04 COG: DR0329; COG0494 NTP pyrophosphohydrolases including oxidative damage; E=3e-05 DR0004; COG0494 NTP pyrophosphohydrolases including oxidative; E=4e-05 DR0550; COG0494 NTP pyrophosphohydrolases including oxidative damage; E=1e-04 PFAM: PF00293; MutT-like domain; E=4.8e-17.
  
 
 0.922
rplE
50S ribosomal protein L5; This is 1 of the proteins that binds and probably mediates the attachment of the 5S RNA into the large ribosomal subunit, where it forms part of the central protuberance. In the 70S ribosome it contacts protein S13 of the 30S subunit (bridge B1b), connecting the 2 subunits; this bridge is implicated in subunit movement. Contacts the P site tRNA; the 5S rRNA and some of its associated proteins might help stabilize positioning of ribosome-bound tRNAs.
   
 
 0.914
rplW
50S ribosomal protein L23; One of the early assembly proteins it binds 23S rRNA. One of the proteins that surrounds the polypeptide exit tunnel on the outside of the ribosome. Forms the main docking site for trigger factor binding to the ribosome; Belongs to the universal ribosomal protein uL23 family.

pnp-2
Polyribonucleotide nucleotidyltransferase; Involved in mRNA degradation. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3'- to 5'- direction.
  
  
 0.882
rplR
50S ribosomal protein L18; This is one of the proteins that binds and probably mediates the attachment of the 5S RNA into the large ribosomal subunit, where it forms part of the central protuberance.
