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

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. (213 aa)    
Predicted Functional Partners:
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.

hisA
TIGRFAM: phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase; PFAM: histidine biosynthesis protein; KEGG: ccr:CC_3736 phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase.
 
 
 0.999
hisB
PFAM: imidazoleglycerol-phosphate dehydratase; KEGG: ccr:CC_3734 imidazoleglycerol-phosphate dehydratase.
 
 
 0.999
hisE
TIGRFAM: phosphoribosyl-ATP diphosphatase; PFAM: phosphoribosyl-ATP pyrophosphohydrolase; KEGG: ccr:CC_3738 phosphoribosyl-ATP pyrophosphatase.
 
  
 0.998
hisI
Phosphoribosyl-AMP cyclohydrolase; Catalyzes the hydrolysis of the adenine ring of phosphoribosyl-AMP.
 
  
 0.994
hisD
Histidinol dehydrogenase; Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine.
 
  
 0.994
Caul_4679
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.
 
  
 0.993
hisC-2
PFAM: aminotransferase class I and II; KEGG: ccr:CC_2534 histidinol-phosphate aminotransferase; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. Histidinol-phosphate aminotransferase subfamily.
 
  
 0.925
Caul_4680
PFAM: tRNA synthetase class II (G H P and S); KEGG: ccr:CC_3512 ATP phosphoribosyltransferase regulatory subunit.
  
  
 0.911
hisC
TIGRFAM: histidinol-phosphate aminotransferase; PFAM: aminotransferase class I and II; KEGG: ccr:CC_2223 histidinol-phosphate aminotransferase; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. Histidinol-phosphate aminotransferase subfamily.
