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

hisFImidazoleglycerol 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. (256 aa)    
Predicted Functional Partners:
hisIE
Histidine biosynthesis bifunctional protein HisIE; In the N-terminal section; belongs to the PRA-CH family.
  
 0.999
hisH
Imidazole glycerol phosphate synthase, glutamine amidotransferase subunit.
 0.999
hisB
Imidazoleglycerol-phosphate dehydratase.
 
 
 0.998
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.
 
 
0.996
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.
 
  
 0.984
hisC
Aminotransferases class-I.
 
  
 0.892
purH
Phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase.
  
 
 0.854
hisC/cobC
L-threonine-O-3-phosphate decarboxylase, putative.
 
  
 0.848
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
   
 
 0.822
