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

arcTPutative transaminase/peptidase; Identified by similarity to GB:AAN65259.1; match to protein family HMM PF01546; match to protein family HMM TIGR01887. (444 aa)    
Predicted Functional Partners:
arcD
Arginine-ornithine antiporter; Identified by similarity to GB:AAN65258.1; match to protein family HMM PF03606.
 
   
 0.959
arcC
Carbamate kinase; Identified by match to protein family HMM PF00696; match to protein family HMM TIGR00746; Belongs to the carbamate kinase family.
     
 0.819
arcB
Ornithine carbamoyltransferase; Reversibly catalyzes the transfer of the carbamoyl group from carbamoyl phosphate (CP) to the N(epsilon) atom of ornithine (ORN) to produce L-citrulline; Belongs to the aspartate/ornithine carbamoyltransferase superfamily. OTCase family.
  
  
 0.767
arcA
Arginine deiminase; Identified by similarity to GB:AAN65255.1; match to protein family HMM PF02274; match to protein family HMM TIGR01078; Belongs to the arginine deiminase family.
 
  
 0.751
arcR
Arginine repressor; In the presence of arginine, coactivates the transcription of the arcABDC operon, with other regulatory proteins such as ArcR and CcpA.
     
 0.644
queA
S-adenosylmethionine:tRNA ribosyltransferase-isomerase; Transfers and isomerizes the ribose moiety from AdoMet to the 7-aminomethyl group of 7-deazaguanine (preQ1-tRNA) to give epoxyqueuosine (oQ-tRNA) (By similarity). Seems to have a role in modulation of ADS (arginine deiminase system) gene expression, perhaps exerting a negative effect on the translation of arc regulatory proteins.
