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

Score
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. (211 aa)    
Predicted Functional Partners:
hisA
KEGG: ana:all4506 2.1e-119 hisA; 1-(5-phosphoribosyl)-5-[(5- phosphoribosylamino)methylideneamino] imidazole-4-carboxamide isomerase K01814; Psort location: Cytoplasmic, score: 9.97.
 
 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
hisI
KEGG: npu:Npun_F4098 6.9e-105 phosphoribosyl-AMP cyclohydrolase K11755; Psort location: Cytoplasmic, score: 9.97; In the N-terminal section; belongs to the PRA-CH family.
 
 
 0.997
hisB
KEGG: ana:all4390 4.8e-97 hisB; imidazoleglycerol-phosphate dehydratase K01693; Psort location: Cytoplasmic, score: 9.97.
 
 
 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.
 
  
 0.983
hisC-2
KEGG: npu:Npun_R0752 2.3e-159 histidinol-phosphate aminotransferase K00817; Psort location: Cytoplasmic, score: 8.96; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. Histidinol-phosphate aminotransferase subfamily.
 
 
 0.978
EKE99141.1
Threonine-phosphate decarboxylase; KEGG: npu:Npun_F5011 1.2e-153 putative L-threonine-O-3-phosphate decarboxylase; Psort location: CytoplasmicMembrane, score: 9.86.
 
 
 0.977
hisC
Putative histidinol-phosphate transaminase; KEGG: npu:Npun_R0899 5.6e-158 aminotransferase, class I and II K00817; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. Histidinol-phosphate aminotransferase subfamily.
 
 
 0.974
hisD
Histidinol dehydrogenase; Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine.
 
  
 0.969
hisD-2
Histidinol dehydrogenase; Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine.
