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.

hisFImidazoleglycerol phosphate synthase; 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. (254 aa)    
Predicted Functional Partners:
hisB
Imidazoleglycerol-phosphate dehydratase; Identified by sequence similarity; putative; ORF located using Glimmer/GeneMark/Blastx/COG0131.
 
 0.999
hisH
Amidophosphoribosyltransferase; 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.
 0.999
hisI
phosphoribosyl-AMP cyclohydrolase; Catalyzes the hydrolysis of the adenine ring of phosphoribosyl-AMP.
  
 0.999
hisD
Histidinol dehydrogenase; Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine.
  
 0.998
hisA
Phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase; Identified by sequence similarity; putative; ORF located using GeneMark/Blastx/COG0106.
 
 
0.998
hisE
phosphoribosyl-ATP pyrophosphohydrolase; Identified by sequence similarity; putative; ORF located using Blastx/COG0140.
 
  
 0.995
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.
 
  
 0.992
hisC
Histidinol-phosphate aminotransferase; Identified by sequence similarity; putative; ORF located using Glimmer/GeneMark/Blastx/COG0079; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. Histidinol-phosphate aminotransferase subfamily.
 
  
 0.968
CV_0038
Probable histidinol-phosphate aminotransferase; Identified by sequence similarity; putative; ORF located using GeneMark/Blastx/COG0079.
 
  
 0.937
hisZ
Conserved hypothetical protein; Required for the first step of histidine biosynthesis. May allow the feedback regulation of ATP phosphoribosyltransferase activity by histidine.
 
  
 0.931
