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; Alternative locus ID: PMED4_08821. (255 aa)    
Predicted Functional Partners:
hisI
Phosphoribosyl-AMP cyclohydrolase; Alternative locus ID: PMED4_06271; In the C-terminal section; belongs to the PRA-PH family.
 
 0.999
hisH
Glutamine amidotransferase class-I; 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
hisF
Imidazole glycerol phosphate synthase subunit 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.
 
 
0.992
hisD
Histidinol dehydrogenase; Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine.
 
  
 0.974
hisB
Imidazoleglycerol-phosphate dehydratase; Alternative locus ID: PMED4_02861.
  
 0.969
hisG
Possible 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. Short subfamily.
 
  
 0.953
hisC/cobC
Aminotransferases class-I; Citation: Crouzet et al. (1990) J. Bacteriol. 172:5968-5979; Alternative locus ID: PMED4_02041.
  
  
 0.808
hisC
Aminotransferases class-I; Conserved hypothetical assignment; Alternative locus ID: PMED4_01921.
  
  
 0.805
guaA
Glutamine amidotransferase class-I:GMP synthase; Catalyzes the synthesis of GMP from XMP.
  
  
 0.758
PMM1214
Possible phosphatase; Alternative locus ID: PMED4_13791; Belongs to the gmhB family.
  
  
 0.702
