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

hisAPhosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase; Involved in both the histidine and tryptophan biosynthetic pathways; Belongs to the HisA/HisF family. (245 aa)    
Predicted Functional Partners:
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 (By similarity).
 
 
 0.999
hisF
Cyclase; 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).
 
0.999
hisI
phosphoribosyl-AMP 1,6 cyclohydrolase; Catalyzes the hydrolysis of the adenine ring of phosphoribosyl-AMP.
 
 0.999
hisB
Highly similar to many imidazoleglycerol-phosphate dehydratases (EC 4.2.1.19) involved in histidine biosynthesis e.g. from Mycobacterium tuberculosis RV1601 SW:HIS7_MYCTU (O06590) (210 aa); Fasta score E(): 0, 84.8% identity in 210 aa overlap and Streptomyces coelicolor SW:HIS7_STRCO (P16247) (197 aa); Fasta score E(): 0, 56.4% identity in 202 aa overlap. Contains 2 Pfam matches to entry PF00475 IGPD, Imidazoleglycerol-phosphate dehydratase. Contains PS00955 Imidazoleglycerol-phosphate dehydratase signature 2. Contains PS00954 Imidazoleglycerol-phosphate dehydratase signature 1.
 
  
 0.998
hisD
Histidinol dehydrogenase; Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine.
 
  
 0.997
hisC
Highly similar to many histidinol-phosphate aminotransferases (EC 2.6.1.9) involved in histidine biosynthesis e.g. Mycobacterium tuberculosis RV1600 TR:SW:HIS8_MYCTU (O06591) (380 aa); Fasta score E(): 0, 83.6% identity in 366 aa overlap and Mycobacterium smegmatis SW:HIS8_MYCSM (P28735) (219 aa); Fasta score E(): 0, 77.2% identity in 219 aa overlap. Contains Pfam match to entry PF00222 aminotran_2, Aminotransferases class-II.
 
  
 0.991
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 (By similarity).
 
  
 0.970
trpC
Highly similar to many indole-3-glycerol phosphate synthases (EC 4.1.1.48) involved in tryptophan biosynthesis e.g. Mycobacterium tuberculosis Rv1611 SW:TRPC_MYCTU (O06129) (272 aa); Fasta score E(): 0, 90.8% identity in 272 aa overlap and Streptomyces coelicolor SW:TRC1_STRCO (O68814) (269 aa); Fasta score E(): 0, 64.1% identity in 262 aa overlap. Contains Pfam match to entry PF00218 IGPS, Indole-3-glycerol phosphate synthases. Contains PS00614 Indole-3-glycerol phosphate synthase signature.
  
 
 0.953
hisE
Highly similar to several phosphoribosyl-ATP pyrophosphatases (EC 3.6.1.31) involved in histidine biosynthesis, including: Sulfolobus solfataricus HisE SW:HIS2_SULSO (O33776) (94 aa); Fasta score E(): 0.00013, 32.5% identity in 83 aa overlap and Mycobacterium tuberculosis RV2122C SW:HIS2_MYCTU (O33257) (93 aa); Fasta score E(): 2.5e-31, 86.0% identity in 93 aa overlap. Contains Pfam match to entry PF01503 PRA-PH, Phosphoribosyl-ATP pyrophosphohydrolase.
  
  
 0.946
trpD
Putative anthranilate phosphoribosyltransferase; Catalyzes the transfer of the phosphoribosyl group of 5- phosphorylribose-1-pyrophosphate (PRPP) to anthranilate to yield N-(5'- phosphoribosyl)-anthranilate (PRA).
