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.

hisBBifunctional imidazoleglycerol-phosphate dehydratase HisB. (200 aa)    
Predicted Functional Partners:
hisF
Imidazoleglycerol-phosphate synthase cyclase 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.
 
 
 0.999
hisC
Histidinol-phosphate aminotransferase HisC.
 
 0.999
hisD
Histidinol dehydrogenase HisD; Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine.
  
 0.999
hisH
Imidazole glycerol phosphate synthase glutamine amidotransferase 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.
 
 
 0.998
hisG1
ATP phosphoribosyltransferase HisG1; 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. Long subfamily.
 
  
 0.991
hisA
Phosphoribosylformimino-5- aminoimidazole carboxamide ribotide isomerase HisA.
 
  
 0.988
hisI
phosphoribosyl-AMP cyclohydrolase HisI; Catalyzes the hydrolysis of the adenine ring of phosphoribosyl-AMP.
 
  
 0.986
hisE
phosphoribosyl-ATP pyrophosphohydrolase HisE.
  
  
 0.953
hisG2
ATP phosphoribosyltransferase HisG2.
 
  
 0.937
nadK-2
Bifunctional inositol-1 monophosphatase/fructose-1,6-bisphosphatase/ATP-NAD kinase; Involved in the regulation of the intracellular balance of NAD and NADP, and is a key enzyme in the biosynthesis of NADP. Catalyzes specifically the phosphorylation on 2'-hydroxyl of the adenosine moiety of NAD to yield NADP.
