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

hisDHistidinol dehydrogenase; Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine. (437 aa)    
Predicted Functional Partners:
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 (By similarity).
 
  
 0.999
hisC
Histidinol-phosphate aminotransferase; Escherichia coli K-12 ortholog: b2021; Escherichia coli O157:H7 ortholog: z3183; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. Histidinol-phosphate aminotransferase subfamily.
  
 0.999
hisB
Histidine biosynthesis bifunctional protein hisB; Escherichia coli K-12 ortholog: b2022; Escherichia coli O157:H7 ortholog: z3184; bifunctional; Histidinol-phosphatase; Imidazoleglycerol-phosphate dehydratase; In the C-terminal section; belongs to the imidazoleglycerol-phosphate dehydratase family.
 
 0.999
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 (By similarity).
  
 0.999
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.
  
 0.999
hisI
Histidine biosynthesis bifunctional protein hisIE; Escherichia coli K-12 ortholog: b2026; Escherichia coli O157:H7 ortholog: z3188; bifunctional; Phosphoribosyl-AMP cyclohydrolase; Phosphoribosyl-ATP pyrophosphatase; In the C-terminal section; belongs to the PRA-PH family.
  
 0.999
hisA
1-(5-phosphoribosyl)-5-[(5- phosphoribosylamino)methylideneamino] imidazole-4-carboxamide isomerase; Escherichia coli K-12 ortholog: b2024; Escherichia coli O157:H7 ortholog: z3186; Belongs to the HisA/HisF family.
  
 0.997
thrA
Bifunctional; Escherichia coli K-12 ortholog: b0002; Escherichia coli O157:H7 ortholog: z0002; bifunctional; Homoserine dehydrogenase I; In the C-terminal section; belongs to the homoserine dehydrogenase family.
 
  
 0.923
aroC
Chorismate synthase; Catalyzes the anti-1,4-elimination of the C-3 phosphate and the C-6 proR hydrogen from 5-enolpyruvylshikimate-3-phosphate (EPSP) to yield chorismate, which is the branch point compound that serves as the starting substrate for the three terminal pathways of aromatic amino acid biosynthesis. This reaction introduces a second double bond into the aromatic ring system.
 
  
 0.887
purE
Phosphoribosylaminoimidazole carboxylase catalytic subunit; Catalyzes the conversion of N5-carboxyaminoimidazole ribonucleotide (N5-CAIR) to 4-carboxy-5-aminoimidazole ribonucleotide (CAIR).
