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

hisAN-(5'-phospho-L-ribosyl-formimino)-5-amino-1- (5'-phosphoribosyl)-4-imidazolecarboxamide isomerase; Phosphoribosylformimino-5-aminoimidazole carboxamide ribotideisomerase. (SW:HIS4_SALTY). (245 aa)    
Predicted Functional Partners:
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); Belongs to the ATP phosphoribosyltransferase family. Long subfamily.
 
  
 0.999
hisD
Histidinal dehydrogenase; Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine.
  
 0.999
hisB
Imidazole glycerol-phosphate dehydratase; Bifunctional; histidine biosynthesis bifunctional protein HISB [includes:histidinol-phosphatase ]. (SW:HIS7_SALTY); In the C-terminal section; belongs to the imidazoleglycerol-phosphate dehydratase family.
  
 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 (By similarity).
 
 0.999
hisF
Imidazole glycerol 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 (By similarity).
 
0.999
hisI
phosphoribosyl-AMP cyclohydrolase; Bifunctional; histidine biosynthesis bifunctional protein HISIE [includes:phosphoribosyl-amp cyclohydrolase ]. (SW:HIS2_SALTY); phosphoribosyl-ATP pyrophosphatase; In the C-terminal section; belongs to the PRA-PH family.
 
 0.999
hisC
Histidinol-phosphate aminotransferase. (SW:HIS8_SALTY); Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. Histidinol-phosphate aminotransferase subfamily.
 
  
 0.998
trpC
N-(5-phosphoribosyl)anthranilate isomerase; Bifunctional enzyme that catalyzes two sequential steps of tryptophan biosynthetic pathway. The first reaction is catalyzed by the isomerase, coded by the TrpF domain; the second reaction is catalyzed by the synthase, coded by the TrpC domain (By similarity).
 
  
 0.891
cobD
Putative aminotransferase in cobalamin synthesis; 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.
 
  
 0.829
trpD
Anthranilate synthase, component II; Part of a heterotetrameric complex that catalyzes the two- step biosynthesis of anthranilate, an intermediate in the biosynthesis of L-tryptophan. In the first step, the glutamine-binding beta subunit (TrpG) of anthranilate synthase (AS) provides the glutamine amidotransferase activity which generates ammonia as a substrate that, along with chorismate, is used in the second step, catalyzed by the large alpha subunit of AS (TrpE) to produce anthranilate. In the absence of TrpG, TrpE can synthesize anthranilate directly from chorismate and high concen [...]
