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.

Score
hisZATP phosphoribosyltransferase regulatory subunit; Required for the first step of histidine biosynthesis. May allow the feedback regulation of ATP phosphoribosyltransferase activity by histidine. (409 aa)    
Predicted Functional Partners:
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.
 
 0.981
hisIE
Histidine biosynthesis bifunctional protein HisIE; Identified by similarity to SP:O34912; match to protein family HMM PF01502; match to protein family HMM PF01503; In the N-terminal section; belongs to the PRA-CH family.
  
 
 0.955
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.
  
 
 0.817
suhB,ssyA
Inositol-1-monophosphatase; Identified by match to protein family HMM PF00459; Belongs to the inositol monophosphatase superfamily.
  
    0.815
sync_1394
Ferredoxin, 2Fe-2S; Identified by match to protein family HMM PF00111.
       0.812
aspS
aspartyl-tRNA synthetase; Aspartyl-tRNA synthetase with relaxed tRNA specificity since it is able to aspartylate not only its cognate tRNA(Asp) but also tRNA(Asn). Reaction proceeds in two steps: L-aspartate is first activated by ATP to form Asp-AMP and then transferred to the acceptor end of tRNA(Asp/Asn); Belongs to the class-II aminoacyl-tRNA synthetase family. Type 1 subfamily.
  
  
 0.772
htpG
Chaperone protein HtpG; Identified by similarity to SP:Q9S3Q2; match to protein family HMM PF00183; match to protein family HMM PF02518.
 
 
 
 0.768
sync_1397
Iron-sulfur cluster-binding protein; Ferredoxins are iron-sulfur proteins that transfer electrons in a wide variety of metabolic reactions.
       0.725
pheT
phenylalanyl-tRNA synthetase, beta subunit; Identified by match to protein family HMM PF01588; match to protein family HMM PF03147; match to protein family HMM PF03483; match to protein family HMM PF03484; match to protein family HMM TIGR00472; Belongs to the phenylalanyl-tRNA synthetase beta subunit family. Type 1 subfamily.
