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 (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. (288 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.
  
 0.999
hisE
phosphoribosyl-AMP cyclohydrolase/phosphoribosyl-ATP pyrophosphohydrolase (hisIE); Similar to SP:P06989 GB:D43637 GB:U02072 GB:X03974 PID:41700 percent identity: 30.43; identified by sequence similarity; putative.
  
 
 0.998
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).
  
 0.998
hisA
Phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase (hisA1); Similar to SP:P10371 PID:41713 GB:U00096 PID:1736702 PID:1736711 percent identity: 32.64; identified by sequence similarity; putative.
  
 0.996
hisB
Imidazoleglycerol-phosphate dehydrogenase/histidinol-phosphatase (hisB); Similar to SP:P06987 GB:X03416 PID:41696 PID:41711 GB:U00096 percent identity: 47.09; identified by sequence similarity; putative.
 
  
 0.994
hisS
histidyl-tRNA synthetase (hisS); Similar to SP:P30053 percent identity: 35.44; identified by sequence similarity; putative; Belongs to the class-II aminoacyl-tRNA synthetase family.
 
 
 0.994
hisI
phosphoribosyl-AMP cyclohydrolase/phosphoribosyl-ATP pyrophosphohydrolase (hisIE); Catalyzes the hydrolysis of the adenine ring of phosphoribosyl-AMP.
 
  
 0.994
hisH
Imidazole glycerol 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).
 
  
 0.990
hisC
Histidinol-phosphate aminotransferase (hisC); Similar to SP:P06986 GB:U02071 GB:X03416 PID:41695 PID:41710 percent identity: 29.00; identified by sequence similarity; putative.
  
 0.990
prs
Ribose-phosphate pyrophosphokinase, (prsA); 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). It can also use dATP as diphosphoryl donor.
