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

Score
hisA1-(5-phosphoribosyl)-5-[(5- phosphoribosylamino)methylideneamino]imidazole-4- carboxamide isomerase; Identified by match to protein family HMM PF00977; match to protein family HMM TIGR02129; Belongs to the HisA/HisF family. (258 aa)    
Predicted Functional Partners:
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.
  
 
 0.998
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
hisI
phosphoribosyl-AMP cyclohydrolase; Catalyzes the hydrolysis of the adenine ring of phosphoribosyl-AMP.
  
 
 0.996
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.
  
 
 0.986
hisD
Histidinol dehydrogenase; Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine.
  
 
 0.986
hisB
Imidazoleglycerol-phosphate dehydratase; Identified by match to protein family HMM PF00475.
  
 
 0.982
guaA
GMP synthase (glutamine-hydrolyzing), C-terminal domain protein; Catalyzes the synthesis of GMP from XMP.
  
 
 0.980
hisE
phosphoribosyl-ATP diphosphatase; An automated process has identified a potential problem with this gene model; the current end5 and/or the end3 may need to extended or the current gene model may need to be merged with a neighboring gene model; the current gene model (or a revised gene model) may contain one or more premature stops and/or frameshifts; identified by match to protein family HMM PF01503; match to protein family HMM PF03819; match to protein family HMM TIGR03188.
  
 
 0.966
hisZ
ATP phosphoribosyltransferase, regulatory subunit; Required for the first step of histidine biosynthesis. May allow the feedback regulation of ATP phosphoribosyltransferase activity by histidine.
  
  
 0.965
trpD
Anthranilate phosphoribosyltransferase; Catalyzes the transfer of the phosphoribosyl group of 5- phosphorylribose-1-pyrophosphate (PRPP) to anthranilate to yield N-(5'- phosphoribosyl)-anthranilate (PRA).
