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.

hisZhistidine--tRNA ligase; Required for the first step of histidine biosynthesis. May allow the feedback regulation of ATP phosphoribosyltransferase activity by histidine. (395 aa)    
Predicted Functional Partners:
hisG
ATP phosphoribosyltransferase catalytic subunit; 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
hisI
COG0107 Imidazoleglycerol-phosphate synthase; In the C-terminal section; belongs to the PRA-PH family.
 
 
 0.999
hisD
Histidinol dehydrogenase; Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine.
 
  
 0.995
hisB
COG0131 Imidazoleglycerol-phosphate dehydratase.
 
  
 0.994
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.
 
  
 0.968
AEN95269.1
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.
 
  
 0.919
AEN96175.1
COG0106 Phosphoribosylformimino-5-aminoimidazole carboxamide ribonucleotide (ProFAR) isomerase; Belongs to the HisA/HisF family.
  
  
 0.916
hisH-2
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.
 
  
 0.893
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.
  
  
 0.876
AEN97745.1
COG0462 Phosphoribosylpyrophosphate synthetase; Belongs to the ribose-phosphate pyrophosphokinase family.
    
 0.837
