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.

Score
hisZtRNA synthetase, class II (G, H, P and S); Required for the first step of histidine biosynthesis. May allow the feedback regulation of ATP phosphoribosyltransferase activity by histidine. (382 aa)    
Predicted Functional Partners:
hisG
ATP phosphoribosyltransferase (homohexameric); 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. Belongs to the ATP phosphoribosyltransferase family. Short subfamily.
 0.999
hisE
phosphoribosyl-ATP pyrophosphatase.
 
 
 0.993
hisA
1-(5-phosphoribosyl)-5-[(5- phosphoribosylamino)methylideneamino] imidazole-4-carboxamide isomerase.
 
  
 0.937
hisD
Histidinol dehydrogenase; Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine.
 
  
 0.936
hisB
Imidazoleglycerol-phosphate dehydratase.
  
  
 0.933
hisH
Imidazole glycerol phosphate synthase subunit hisH; IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The HisH subunit catalyzes the hydrolysis of glutamine to glutamate and ammonia as part of the synthesis of IGP and AICAR. The resulting ammonia molecule is channeled to the active site of HisF.
  
  
 0.932
hisF
Imidazole glycerol phosphate synthase subunit hisF; IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The HisF subunit catalyzes the cyclization activity that produces IGP and AICAR from PRFAR using the ammonia provided by the HisH subunit.
  
  
 0.932
hisI
phosphoribosyl-AMP cyclohydrolase; Catalyzes the hydrolysis of the adenine ring of phosphoribosyl-AMP.
  
  
 0.916
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; Belongs to the adenylosuccinate synthetase family.
  
    0.878
Rfer_0392
Ribose-phosphate pyrophosphokinase; Belongs to the ribose-phosphate pyrophosphokinase family.
    
 0.821
