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

hisFhisF protein; 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). (265 aa)    
Predicted Functional Partners:
hisB
Imidazoleglycerol-phosphate dehydratase; Similar to SP:P48054 PID:1001734 PID:1001734 percent identity: 63.50; identified by sequence similarity; putative.
 
 0.999
hisH
Amidotransferase HisH; 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
hisI
phosphoribosyl-AMP cyclohydrolase/phosphoribosyl-ATP pyrophosphohydrolase; Similar to GB:AL009126 percent identity: 63.29; identified by sequence similarity; putative; In the C-terminal section; belongs to the PRA-PH family.
  
 0.999
hisD
Histidinol dehydrogenase; Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine.
  
 0.999
hisA
Phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase; Similar to PID:1653757 percent identity: 62.88; identified by sequence similarity; putative.
 
0.999
hisC
Histidinol-phosphate aminotransferase; Similar to GB:AE000657 percent identity: 54.20; identified by sequence similarity; putative; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. Histidinol-phosphate aminotransferase subfamily.
 
  
 0.995
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. Short subfamily.
 
  
 0.994
hisZ
histidyl-tRNA synthetase, putative; Required for the first step of histidine biosynthesis. May allow the feedback regulation of ATP phosphoribosyltransferase activity by histidine (By similarity).
  
  
 0.902
purH
Phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase; Similar to GB:J02732 SP:P12048 PID:143373 GB:AL009126 percent identity: 66.73; identified by sequence similarity; putative.
  
 
 0.855
DR_0878
Adenine phosphoribosyltransferase, putative; Similar to GB:L77117 SP:Q59049 PID:1592237 percent identity: 53.60; identified by sequence similarity; putative.
