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

Exig_2367ATP 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. (202 aa)    
Predicted Functional Partners:
Exig_2360
phosphoribosyl-AMP cyclohydrolase; Catalyzes the hydrolysis of the adenine ring of phosphoribosyl-AMP; Belongs to the PRA-CH family.
 
  
 0.999
Exig_2368
KEGG: lme:LEUM_1555 two domain histidine biosynthesis protein, ATP phosphoribosyltransferase (HisG/HisZ fusion).
 
 0.999
Exig_2359
TIGRFAM: phosphoribosyl-ATP diphosphatase; PFAM: phosphoribosyl-ATP pyrophosphohydrolase; KEGG: lpl:lp_2552 phosphoribosyl-ATP pyrophosphatase; Belongs to the PRA-PH family.
 
 
 0.998
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.
 
  
 0.997
hisA
TIGRFAM: phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase; PFAM: histidine biosynthesis protein; KEGG: rca:Rcas_2920 phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase.
 
  
 0.997
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.
 
  
 0.997
hisB
PFAM: imidazoleglycerol-phosphate dehydratase; KEGG: sgo:SGO_1407 imidazoleglycerol-phosphate dehydratase (IGPD).
 
  
 0.997
Exig_2365
PFAM: aminotransferase class I and II; KEGG: tex:Teth514_1002 histidinol-phosphate aminotransferase.
 
  
 0.997
hisD
Histidinol dehydrogenase; Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine.
 
  
 0.997
hisS
KEGG: oih:OB2020 histidyl-tRNA synthetase; TIGRFAM: histidyl-tRNA synthetase; PFAM: tRNA synthetase class II (G H P and S); Anticodon-binding domain protein.
 
 
 0.865
