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

hisGATP 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. Long subfamily. (333 aa)    
Predicted Functional Partners:
hisI
PFAM: phosphoribosyl-AMP cyclohydrolase; phosphoribosyl-ATP pyrophosphohydrolase; KEGG: rrs:RoseRS_0207 phosphoribosyl-AMP cyclohydrolase; In the N-terminal section; belongs to the PRA-CH family.
 
 
 0.999
hisD
Histidinol dehydrogenase; Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine.
  
 0.994
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.
 
  
 0.988
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.
 
  
 0.988
hisB
PFAM: imidazoleglycerol-phosphate dehydratase; KEGG: rca:Rcas_3958 imidazoleglycerol-phosphate dehydratase.
 
  
 0.988
hisA
TIGRFAM: phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase; PFAM: histidine biosynthesis protein; KEGG: rca:Rcas_2920 phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase.
 
  
 0.982
hisC
TIGRFAM: histidinol-phosphate aminotransferase; PFAM: aminotransferase class I and II; KEGG: rca:Rcas_0200 histidinol-phosphate aminotransferase; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. Histidinol-phosphate aminotransferase subfamily.
 
  
 0.970
Haur_1052
PFAM: aminotransferase class I and II; KEGG: rrs:RoseRS_0576 aminotransferase, class I and II.
 
  
 0.931
Haur_2621
KEGG: rrs:RoseRS_4537 ribose-phosphate pyrophosphokinase; TIGRFAM: ribose-phosphate pyrophosphokinase; PFAM: phosphoribosyltransferase.
  
 
 0.855
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.
