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

Tmar_0597Histidine--tRNA ligase; COGs: COG0124 Histidyl-tRNA synthetase; InterPro IPR002314; KEGG: sth:STH2839 histidyl-tRNA synthetase; PFAM: tRNA synthetase class II (G H P and S); PRIAM: Histidine--tRNA ligase; SPTR: ATP phosphoribosyltransferase regulatory subunit. (546 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. Belongs to the ATP phosphoribosyltransferase family. Short subfamily.

hisI
phosphoribosyl-ATP diphosphatase; COGs: COG0139 Phosphoribosyl-AMP cyclohydrolase; InterPro IPR008179: IPR002496: IPR021130; KEGG: rxy:Rxyl_2116 phosphoribosyl-AMP cyclohydrolase / phosphoribosyl-ATP pyrophosphatase; PFAM: phosphoribosyl-AMP cyclohydrolase; Phosphoribosyl-ATP pyrophosphohydrolase-like; SPTR: Phosphoribosyl-AMP cyclohydrolase / phosphoribosyl-ATP pyrophosphatase; TIGRFAM: phosphoribosyl-ATP diphosphatase; PFAM: Phosphoribosyl-ATP pyrophosphohydrolase; Phosphoribosyl-AMP cyclohydrolase; TIGRFAM: phosphoribosyl-ATP pyrophosphohydrolase; In the N-terminal section; belongs [...]
 
 
 0.978
hisD
Histidinol dehydrogenase; Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine.
  
  
 0.888
hisB
COGs: COG0131 Imidazoleglycerol-phosphate dehydratase; InterPro IPR020565: IPR000807; KEGG: slp:Slip_0613 imidazoleglycerol-phosphate dehydratase; PFAM: imidazoleglycerol-phosphate dehydratase; PRIAM: Imidazoleglycerol-phosphate dehydratase; SPTR: Imidazoleglycerol-phosphate dehydratase; PFAM: Imidazoleglycerol-phosphate dehydratase.
 
  
 0.843
aspS
aspartyl-tRNA synthetase; Catalyzes the attachment of L-aspartate to tRNA(Asp) in a two-step reaction: L-aspartate is first activated by ATP to form Asp- AMP and then transferred to the acceptor end of tRNA(Asp). Belongs to the class-II aminoacyl-tRNA synthetase family. Type 1 subfamily.
 
  
 0.835
prs
Ribose-phosphate pyrophosphokinase; Involved in the biosynthesis of the central metabolite phospho-alpha-D-ribosyl-1-pyrophosphate (PRPP) via the transfer of pyrophosphoryl group from ATP to 1-hydroxyl of ribose-5-phosphate (Rib- 5-P); Belongs to the ribose-phosphate pyrophosphokinase family. Class I subfamily.
  
 
 0.827
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.
 
   
 0.767
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.
  
  
 0.712
hisA
Histidine biosynthesis protein; COGs: COG0106 Phosphoribosylformimino-5-aminoimidazole carboxamide ribonucleotide (ProFAR) isomerase; InterPro IPR006062; KEGG: mta:Moth_2032 1-(5-phosphoribosyl)-5-[(5- phosphoribosylamino)methylideneamino] imidazole-4-carboxamide isomerase; PFAM: histidine biosynthesis protein; SPTR:1-(5-phosphoribosyl)-5-[(5- phosphoribosylamino)methylideneamino] imidazole-4-carboxamide isomerase; PFAM: Histidine biosynthesis protein; TIGRFAM: phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase.
     
 0.708
valS
valyl-tRNA synthetase; Catalyzes the attachment of valine to tRNA(Val). As ValRS can inadvertently accommodate and process structurally similar amino acids such as threonine, to avoid such errors, it has a 'posttransfer' editing activity that hydrolyzes mischarged Thr-tRNA(Val) in a tRNA- dependent manner; Belongs to the class-I aminoacyl-tRNA synthetase family. ValS type 1 subfamily.
