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.

hisDHistidinol dehydrogenase; Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine. (433 aa)    
Predicted Functional Partners:
hisB
COGs: COG0131 Imidazoleglycerol-phosphate dehydratase; InterPro IPR020565:IPR000807; KEGG: csc:Csac_2023 imidazoleglycerol-phosphate dehydratase; PFAM: imidazoleglycerol-phosphate dehydratase; PRIAM: Imidazoleglycerol-phosphate dehydratase; SPTR: Imidazoleglycerol-phosphate dehydratase; PFAM: Imidazoleglycerol-phosphate dehydratase.

hisH
Imidazole glycerol phosphate synthase subunit 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.

hisF
Imidazole glycerol phosphate synthase subunit hisF; 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.
  
 0.998
hisG
ATP phosphoribosyltransferase catalytic subunit; 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.
