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 (hisG); 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); Belongs to the ATP phosphoribosyltransferase family. Long subfamily. (281 aa)    
Predicted Functional Partners:
hisD
Histidinol dehydrogenase (hisD); Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine.
 
  
 0.997
hisF
Imidazoleglycerol-phosphate synthase, cyclase 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 (By similarity).
 
  
 0.997
hisB
Imidazoleglycerol-phosphate dehydrogenase/histidinol-phosphatase (hisB); Similar to GB:L77117 SP:Q58109 PID:1591413 percent identity: 42.24; identified by sequence similarity; putative.
 
  
 0.997
hisH
Imidazoleglycerol-phosphate synthase, subunit H (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).
 
  
 0.997
hisA
Phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase (hisA-2); Similar to GB:L77117 SP:Q58927 PID:1592163 percent identity: 42.24; identified by sequence similarity; putative.
 
  
 0.996
hisI
phosphoribosyl-AMP cyclohydrolase/phosphoribosyl-ATP pyrophosphohydrolase (hisIE); Catalyzes the hydrolysis of the adenine ring of phosphoribosyl-AMP.
 
  
 0.996
trpCD
Anthranilate synthase component II (trpD); Bifunctional enzyme that catalyzes the second and fourth steps of tryptophan biosynthetic pathway. The second step is catalyzed by the anthranilate phosphoribosyltransferase, coded by the TrpD domain and the fourth step is catalyzed by indole-3-glycerol phosphate synthase, coded by the TrpC domain (By similarity).
  
  
 0.961
prs1
Ribose-phosphate pyrophosphokinase (prsA-1); 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).
 
 
 0.936
hisS
histidyl-tRNA synthetase (hisS); Similar to GB:L77117 SP:Q58406 PID:1591660 percent identity: 45.97; identified by sequence similarity; putative; Belongs to the class-II aminoacyl-tRNA synthetase family.
  
 
 0.914
hisC1
Histidinol-phosphate aminotransferase (hisC-1); Similar to GB:L77117 PID:1591622 percent identity: 39.76; identified by sequence similarity; putative.
