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

Score
hisZATP phosphoribosyltransferase regulatory subunit; Required for the first step of histidine biosynthesis. May allow the feedback regulation of ATP phosphoribosyltransferase activity by histidine. (392 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.

hisI
PFAM: Phosphoribosyl-AMP cyclohydrolase; Phosphoribosyl-ATP pyrophosphohydrolase-like; TIGRFAM: Phosphoribosyl-ATP pyrophosphohydrolase; HAMAP: Phosphoribosyl-ATP pyrophosphohydrolase; Histidine biosynthesis bifunctional protein HisIE; KEGG: pmf:P9303_18291 bifunctional phosphoribosyl-AMP cyclohydrolase/phosphoribosyl-ATP pyrophosphatase protein; In the N-terminal section; belongs to the PRA-CH family.
  
 
 0.942
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.
    
 0.872
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.

EHA63430.1
KEGG: pmf:P9303_15251 heat shock protein 90; PFAM: ATPase-like, ATP-binding domain; Heat shock protein Hsp90, C-terminal; SMART: ATPase-like, ATP-binding domain.

EHA63429.1
4Fe-4S ferredoxin iron-sulfur binding domain-containing protein; Ferredoxins are iron-sulfur proteins that transfer electrons in a wide variety of metabolic reactions.
       0.697
EHA63427.1
PFAM: Inositol monophosphatase; KEGG: pmt:PMT0699 inositol phosphatase/fructose-1,6-bisphosphatase.
       0.665
EHA63426.1
PFAM: Ferredoxin; KEGG: pmf:P9303_29191 ferredoxin, PetF like protein.

 0.643
guaA
GMP synthase (glutamine-hydrolyzing); Catalyzes the synthesis of GMP from XMP.
