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

hisFImidazole glycerol phosphate synthase 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. (258 aa)    
Predicted Functional Partners:
hisA
Similar to Streptomyces coelicolor phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase HisA or SC4G6.19c SW:HIS4_STRCO (P16250) (240 aa) fasta scores: E(): 2.2e-52, 61.6% id in 237 aa, and to Corynebacterium glutamicum phosphoribosylformimino-5-amino-1-phosphoribosyl-4- imidazolecarboxamide isomerase HisA TR:O68602 (EMBL:AF051846) (245 aa) fasta scores: E(): 8.3e-70, 77.68% id in 242 aa.
 
0.999
hisH
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
Similar to Corynebacterium glutamicum imidazoleglycerol-phosphate dehydrogenase HisB TR:Q9KJU3 (EMBL:AF160479) (205 aa) fasta scores: E(): 2e-49, 66.33% id in 199 aa, and to Streptomyces coelicolor imidazoleglycerol-phosphate dehydratase HisB or SC4G6.21c SW:HIS7_STRCO (P16247) (197 aa) fasta scores: E(): 1.1e-37, 53.03% id in 198 aa.
 
 
 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; 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. Long subfamily.

hisI
phosphoribosyl-AMP cyclohydrolase; Catalyzes the hydrolysis of the adenine ring of phosphoribosyl-AMP.
