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

hisFImidazoleglycerol phosphate synthase, cyclase 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. (253 aa)    
Predicted Functional Partners:
ACP_2335
Putative phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase; Identified by match to protein family HMM PF00977; Belongs to the HisA/HisF family.
 
0.999
hisH
Imidazole glycerol phosphate synthase, glutamine amidotransferase subunit; 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
Imidazoleglycerol-phosphate dehydratase; Identified by match to protein family HMM PF00475.
 
 
 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.
  
 0.999
ACP_2342
phosphoribosyl-AMP cyclohydrolase; Catalyzes the hydrolysis of the adenine ring of phosphoribosyl-AMP; Belongs to the PRA-CH family.
  
 0.999
hisC
Histidinol-phosphate transaminase; Identified by match to protein family HMM PF00155; match to protein family HMM TIGR01141; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. Histidinol-phosphate aminotransferase subfamily.
 
  
 0.997
purH
Bifunctional purine biosynthesis protein PurH; Identified by similarity to SP:P15639; match to protein family HMM PF01808; match to protein family HMM PF02142; match to protein family HMM TIGR00355.
  
 
 0.859
serB
ACT domain protein/phosphoserine phosphatase SerB; Identified by match to protein family HMM PF00702; match to protein family HMM PF01842; match to protein family HMM PF08282; match to protein family HMM TIGR00338; match to protein family HMM TIGR01488.
  
  
 0.854
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
