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.

hisHImidazole glycerol phosphate synthase, glutamine amidotransferase subunit; 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. (202 aa)    
Predicted Functional Partners:
hisB
Imidazoleglycerol-phosphate dehydratase; Function of homologous gene experimentally demonstrated in an other organism; enzyme.
 
 0.999
hisA
Phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase; Function of homologous gene experimentally demonstrated in an other organism; enzyme.
 
 0.999
hisF
Imidazole glycerol phosphate synthase, cyclase subunit; 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.
 0.999
hisI
Fused Phosphoribosyl-AMP cyclohydrolase and Phosphoribosyl-ATP diphosphatase; Function of homologous gene experimentally demonstrated in an other organism; enzyme; In the N-terminal section; belongs to the PRA-CH family.
  
 0.999
hisD
Histidinol dehydrogenase; Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine.
 
  
 0.992
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. Belongs to the ATP phosphoribosyltransferase family. Short subfamily.
 
  
 0.989
cobD
Threonine-phosphate decarboxylase; Function of homologous gene experimentally demonstrated in an other organism; enzyme.
 
  
 0.919
hisC
Histidinol-phosphate aminotransferase; Function of strongly homologous gene; enzyme; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. Histidinol-phosphate aminotransferase subfamily.
 
  
 0.899
hisZ
ATP phosphoribosyltransferase, regulatory subunit; Required for the first step of histidine biosynthesis. May allow the feedback regulation of ATP phosphoribosyltransferase activity by histidine.
  
  
 0.890
purH
Bifunctional purine biosynthesis protein PurH; Function of homologous gene experimentally demonstrated in an other organism; enzyme.
    
 0.854
