STRINGSTRING
hisZ protein (Sideroxydans lithotrophicus) - STRING interaction network
"hisZ" - histidyl-tRNA synthetase 2 in Sideroxydans lithotrophicus
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

hisZhistidyl-tRNA synthetase 2; Required for the first step of histidine biosynthesis. May allow the feedback regulation of ATP phosphoribosyltransferase activity by histidine (385 aa)    
Predicted Functional Partners:
hisG
ATP phosphoribosyltransferase; Catalyzes the condensation of ATP and 5-phosphoribose 1- diphosphate to form N’-(5’-phosphoribosyl)-ATP (PR-ATP). Has a crucial role in the pathway because the rate of histidine biosynthesis seems to be controlled primarily by regulation of HisG enzymatic activity (212 aa)
 
  0.997
hisE
phosphoribosyl-ATP diphosphatase (105 aa)
 
   
  0.968
Slit_1423
HflC protein; HflC and HflK could regulate a protease (292 aa)
              0.912
Slit_1422
HflK protein (396 aa)
              0.912
Slit_1424
Hypothetical protein (61 aa)
   
        0.891
hflX
GTP-binding proten HflX; GTPase that associates with the 50S ribosomal subunit and may have a role during protein synthesis or ribosome biogenesis (380 aa)
              0.847
hfq
RNA chaperone Hfq; RNA chaperone that binds small regulatory RNA (sRNAs) and mRNAs to facilitate mRNA translational regulation in response to envelope stress, environmental stress and changes in metabolite concentrations. Also binds with high specificity to tRNAs (76 aa)
              0.847
purA
Adenylosuccinate synthetase; Plays an important role in the de novo pathway of purine nucleotide biosynthesis. Catalyzes the first committed step in the biosynthesis of AMP from IMP (437 aa)
   
        0.841
prs
Ribose-phosphate pyrophosphokinase; Involved in the biosynthesis of ribose 1,5-bisphosphate. Catalyzes the transfer of pyrophosphoryl group from ATP to ribose- 5-phosphate to yield phosphoribosyl diphosphate (PRPP) and AMP (315 aa)
     
 
    0.802
hisS
histidyl-tRNA synthetase (423 aa)
 
   
0.690
