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.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

hisAPhosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase. (239 aa)    
Predicted Functional Partners:
hisI
phosphoribosyl-ATP pyrophosphohydrolase / phosphoribosyl-AMP cyclohydrolase; Catalyzes the hydrolysis of the adenine ring of phosphoribosyl-AMP.
 
 0.999
hisH
Glutamine amidotransferase; 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
hisF
Imidazoleglycerol 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
hisB
Imidazoleglycerol-phosphate dehydratase.
 
  
 0.998
hisE
phosphoribosyl-ATP diphosphatase.
 
  
 0.997
hisD
Histidinol dehydrogenase; Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine.
 
  
 0.988
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.
 
  
 0.965
hisZ
ATP phosphoribosyltransferase regulatory subunit.
  
  
 0.911
guaA
Guanine monophosphate synthase; Catalyzes the synthesis of GMP from XMP.
  
  
 0.808
hisC
Histidinol-phosphate aminotransferase; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. Histidinol-phosphate aminotransferase subfamily.
  
  
 0.795
