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. (436 aa)    
Predicted Functional Partners:
hisI
TIGRFAM: phosphoribosyl-ATP diphosphatase; PFAM: phosphoribosyl-AMP cyclohydrolase; MazG nucleotide pyrophosphohydrolase; phosphoribosyl-ATP pyrophosphohydrolase; KEGG: ava:Ava_4918 bifunctional phosphoribosyl-AMP cyclohydrolase/phosphoribosyl-ATP pyrophosphatase protein; In the N-terminal section; belongs to the PRA-CH family.
  
 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.
  
 0.998
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.
  
 0.998
hisB
PFAM: imidazoleglycerol-phosphate dehydratase; KEGG: mar:MAE_59380 imidazoleglycerol-phosphate dehydratase.
  
 0.998
hisH
Imidazole 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.
  
 0.995
hisC
PFAM: aminotransferase class I and II; KEGG: ava:Ava_2242 histidinol-phosphate aminotransferase; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. Histidinol-phosphate aminotransferase subfamily.
  
 0.994
hisA
TIGRFAM: phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase; PFAM: histidine biosynthesis protein; KEGG: syn:slr0652 phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase.
 
  
 0.953
ACL46281.1
1-(5-phosphoribosyl)-5-((5- phosphoribosylamino)methylideneamino)imidazole-4- carboxamideisomerase; PFAM: histidine biosynthesis protein; KEGG: syp:SYNPCC7002_A1890 phosphorybosilformimino-5-amino-phosphorybosil-4- imidazolecarboxamid eisomerase; Belongs to the HisA/HisF family.
 
  
 0.951
hisZ
histidyl-tRNA synthetase 2; Required for the first step of histidine biosynthesis. May allow the feedback regulation of ATP phosphoribosyltransferase activity by histidine.
  
  
 0.945
ACL44847.1
TIGRFAM: L-threonine-O-3-phosphate decarboxylase; PFAM: aminotransferase class I and II; KEGG: npu:Npun_F5011 putative L-threonine-O-3-phosphate decarboxylase.
  
 0.943
