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.

hisZhistidyl-tRNA synthetase 2; Required for the first step of histidine biosynthesis. May allow the feedback regulation of ATP phosphoribosyltransferase activity by histidine. (420 aa)    
Predicted Functional Partners:
hisI
phosphoribosyl-ATP diphosphatase; KEGG: tex:Teth514_1007 bifunctional phosphoribosyl-AMP cyclohydrolase/phosphoribosyl-ATP pyrophosphatase protein; TIGRFAM: phosphoribosyl-ATP diphosphatase; PFAM: phosphoribosyl-AMP cyclohydrolase; Phosphoribosyl-ATP pyrophosphohydrolase-like; In the N-terminal section; belongs to the PRA-CH family.
 
 
 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. Short subfamily.
 0.999
hisF
Imidazoleglycerol 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.
 
  
 0.990
hisB
KEGG: tte:TTE2136 imidazoleglycerol-phosphate dehydratase; PFAM: imidazoleglycerol-phosphate dehydratase.
 
  
 0.990
hisD
Histidinol dehydrogenase; Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine.
 
  
 0.990
hisA
TIGRFAM: phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase; KEGG: llc:LACR_1328 1-(5-phosphoribosyl)-5-[(5- phosphoribosylamino)methylideneamino] imidazole-4-carboxamide isomerase; PFAM: histidine biosynthesis protein.
 
  
 0.988
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.
  
  
 0.987
hisC-2
KEGG: pfu:PF1665 histidinol-phosphate aminotransferase; TIGRFAM: histidinol-phosphate aminotransferase; PFAM: aminotransferase class I and II; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. Histidinol-phosphate aminotransferase subfamily.
  
  
 0.931
ADQ14644.1
TIGRFAM: ribose-phosphate pyrophosphokinase; KEGG: cpr:CPR_1519 phosphoribosylpyrophosphate synthetase; PFAM: phosphoribosyltransferase.
 
  
 0.848
prs
Ribose-phosphate pyrophosphokinase; Involved in the biosynthesis of the central metabolite phospho-alpha-D-ribosyl-1-pyrophosphate (PRPP) via the transfer of pyrophosphoryl group from ATP to 1-hydroxyl of ribose-5-phosphate (Rib- 5-P); Belongs to the ribose-phosphate pyrophosphokinase family. Class I subfamily.
