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

nadAQuinolinate synthetase complex, A subunit; Catalyzes the condensation of iminoaspartate with dihydroxyacetone phosphate to form quinolinate. (306 aa)    
Predicted Functional Partners:
AGB03676.1
Nicotinate-nucleotide pyrophosphorylase; Involved in the catabolism of quinolinic acid (QA). Belongs to the NadC/ModD family.
 
 
 0.999
nadX
Aspartate dehydrogenase; Specifically catalyzes the NAD or NADP-dependent dehydrogenation of L-aspartate to iminoaspartate.
    
 0.944
nadE-2
NAD+ synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source.
  
  
 0.843
AGB03461.1
Serine O-acetyltransferase; PFAM: Domain of unknown function DUF59; TIGRFAM: serine O-acetyltransferase.

purL
Phosphoribosylformylglycinamidine (FGAM) synthase, synthetase domain protein; Part of the phosphoribosylformylglycinamidine synthase complex involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate. The FGAM synthase complex is composed of three subunits. PurQ produces an ammonia molecule by converting glutamine to glutamate. PurL transfers the ammonia molecule to FGAR to form FGAM in an ATP- dependent manner. PurS interacts with PurQ and [...]

iscS
Cysteine desulfurase NifS; Master enzyme that delivers sulfur to a number of partners involved in Fe-S cluster assembly, tRNA modification or cofactor biosynthesis. Catalyzes the removal of elemental sulfur atoms from cysteine to produce alanine. Functions as a sulfur delivery protein for Fe-S cluster synthesis onto IscU, an Fe-S scaffold assembly protein, as well as other S acceptor proteins.
