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

hisC2Histidinol phosphate aminotransferase apoenzyme; One of two hisC genes in the Psychrobacter 273-4 genome; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. Histidinol-phosphate aminotransferase subfamily. (377 aa)    
Predicted Functional Partners:
hisB
Imidazoleglycerol-phosphate dehydratase; This orf is probably the monofunctional variety of hisB.
 
 0.997
aroA
3-phosphoshikimate 1-carboxyvinyltransferase / prephenate dehydrogenase; Catalyzes the transfer of the enolpyruvyl moiety of phosphoenolpyruvate (PEP) to the 5-hydroxyl of shikimate-3-phosphate (S3P) to produce enolpyruvyl shikimate-3-phosphate and inorganic phosphate.
  
 
 0.995
hisD
Histidinol dehydrogenase; Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine.
  
 0.990
hisI
phosphoribosyl-AMP cyclohydrolase; This orf aligns to domains of both pyrophosphohydrolase and cyclohydrolase functions, suggesting a bifunctional enzyme; In the N-terminal section; belongs to the PRA-CH family.
 
  
 0.974
pheA
Prephenate dehydratase; Contains 3 domains: chorismate mutase, prephenate dehydratase, and an ACT (amino acid synthesis regulatory domain). This enzyme is bifunctional in the phenylalanine synthesis pathway.
 
 
 0.958
hisH
Imidazole glycerol phosphate synthase 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.
 
  
 0.918
hisC
Aminotransferase; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. Histidinol-phosphate aminotransferase subfamily.
  
  
 
0.910
tyrB
Aromatic amino acid aminotransferase apoenzyme.
   
 
 0.910
hisG
ATP phosphoribosyltransferase (homohexameric); 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.
 
  
 0.905
hisF
Imidazole glycerol phosphate synthase 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.
