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
HisIPhosphoribosyl-AMP cyclohydrolase; Best Blastp hit = gi|6175609|gb|AAF05095.1|AF150930_4 (AF150930) phosphoribosyl-AMP cyclohydrolase [Thermoanaerobacter ethanolicus], score 237, E-value 8.00E-62; In the C-terminal section; belongs to the PRA-PH family. (205 aa)    
Predicted Functional Partners:
HisF
Imidazoleglycerol-phosphate synthase; 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.
  
 0.999
HisA
Phosphoribosylformimino-5-aminoimidazole carboxamide ribonucleotide (ProFAR) isomerase; Best Blastp hit = gi|6175607|gb|AAF05093.1|AF150930_2 (AF150930) phosphoribosyl formimino-5-aminoimidazole isomerase [Thermoanaerobacter ethanolicus], score 186, E-value 3.00E-46.
 
 0.999
HisH
Glutamine amidotransferase; 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.
  
 0.999
HisB
Best Blastp hit = gi|7387773|sp|O33564|HIS7_RHOSH IMIDAZOLEGLYCEROL-PHOSPHATE DEHYDRATASE (IGPD) gi|2398791|emb|CAA60712.1| (X87256) imidazoleglycerol-phosphate dehydratase [Rhodobacter sphaeroides], score 223, E-value 2.00E-57.
  
 0.999
HisC2
Best Blastp hit = gi|7450424|pir||E70478 histidinol-phosphate aminotransferase - Aquifex aeolicus gi|2984289|gb|AAC07813.1| (AE000771) histidinol-phosphate aminotransferase [Aquifex aeolicus], score 230, E-value 2.00E-59.
  
 0.999
HisD
Histidinol dehydrogenase; Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine.
  
 0.999
HisG
ATP phosphoribosyltransferase (histidine biosynthesis); 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.
 
 
 0.999
HisS2
Histidyl-tRNA synthetase; Required for the first step of histidine biosynthesis. May allow the feedback regulation of ATP phosphoribosyltransferase activity by histidine.
  
 
 0.999
HisC
Histidinol-phosphate aminotransferase/Tyrosine aminotransferase; Decarboxylates L-threonine-O-3-phosphate to yield (R)-1- amino-2-propanol O-2-phosphate, the precursor for the linkage between the nucleotide loop and the corrin ring in cobalamin; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family.
  
 0.989
tadA
Cytosine/adenosine deaminases; Catalyzes the deamination of adenosine to inosine at the wobble position 34 of tRNA(Arg2); Belongs to the cytidine and deoxycytidylate deaminase family.
   
  
 0.968
