STRINGSTRING
ABA3 protein (Arabidopsis thaliana) - STRING interaction network
"ABA3" - ABA DEFICIENT 3 in Arabidopsis thaliana
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

ABA3ABA DEFICIENT 3; Sulfurates the molybdenum cofactor. Sulfation of molybdenum is essential for xanthine dehydrogenase (XDH) and aldehyde oxidase (ADO) enzymes in which molybdenum cofactor is liganded by 1 oxygen and 1 sulfur atom in active form. Modulates cold stress- and osmotic stress-responsive gene expression by acting as key regulator of abscisic acid (ABA) biosynthesis (819 aa)    
Predicted Functional Partners:
QS
Quinolinate synthase; Catalyzes the condensation of iminoaspartate with dihydroxyacetone phosphate to form quinolinate. Can complement nadA-deficient E.coli mutant. Essential for the de novo synthesis of NAD. Participates also in cysteine desulfurization mediated by NFS2. Can activate the cysteine desulfurase activity of NFS2 in vitro (718 aa)
   
  0.977
CPSUFE
SufE-like protein; Participates in cysteine desulfurization mediated by NFS2 in chloroplast and NIFS1 in mitochondrion (PubMed-16437155). Activates the cysteine desulfurase activity of NFS2 (PubMed-16455656). Cysteine desulfurization mobilizes sulfur from L-cysteine to yield L-alanine and supplies the inorganic sulfur for iron-sulfur (Fe-S) cluster formation. Glutaredoxins regulate SUFE1 activity by inducing its reduction and deglutathionylation (PubMed-24203231) (371 aa)
   
  0.965
SUFE2
Sulfur E2; Participates in cysteine desulfurization mediated by NFS2. Can activate the cysteine desulfurase activity of NFS2 in vitro. Cysteine desulfurization mobilizes sulfur from L-cysteine to yield L-alanine and supplies the inorganic sulfur for iron- sulfur (Fe-S) cluster formation (258 aa)
   
  0.964
ABA2
ABA DEFICIENT 2; Involved in the biosynthesis of abscisic acid (285 aa)
       
 
  0.960
AAO3
Abscisic-aldehyde oxidase; In higher plants aldehyde oxidases (AO) appear to be homo- and heterodimeric assemblies of AO subunits with probably different physiological functions. AO-delta seems to be involved in the last step of abscisic acid biosynthesis, at least in leaves and seeds. In vitro, AO-delta oxidizes abscisic aldehyde to abscisic acid (ABA). In vitro, AO-delta also uses indole-3- aldehyde (IAld), benzaldehyde, 1-naphthaldehyde and cinnamaldehyde as substrate; the AAO2-AAO3 dimer also uses abscisic aldehyde as substrate (1332 aa)
     
   
  0.953
ABA1
ABA DEFICIENT 1; Zeaxanthin epoxidase that plays an important role in the xanthophyll cycle and abscisic acid (ABA) biosynthesis. Converts zeaxanthin into antheraxanthin and subsequently violaxanthin. Required for resistance to osmotic and drought stresses, ABA- dependent stomatal closure, seed development and dormancy, modulation of defense gene expression and disease resistance and non-photochemical quencing (NPQ). Through its role in ABA biosynthesis, regulates the expression of stress-responsive genes such as RD29A during osmotic stress and is required for normal plant growth durin [...] (667 aa)
     
 
  0.952
AAO1
Aldehyde oxidase 1; In higher plants aldehyde oxidases (AO) appear to be homo- and heterodimeric assemblies of AO subunits with probably different physiological functions. AO-alpha may be involved in the biosynthesis of auxin, and in biosynthesis of abscisic acid (ABA) in seeds. In vitro, AO-alpha uses heptaldehyde, protocatechualdehyde, benzaldehyde, indole-3-aldehyde (IAld), indole-3-acetaldehyde (IAAld), cinnamaldehyde and citral as substrates; AO-beta uses IAAld, IAld and naphtaldehyde as substrates (1368 aa)
     
   
  0.948
NFS1
Cysteine desulfurase 1; Catalyzes the removal of elemental sulfur from cysteine to produce alanine. Supplies the inorganic sulfur for iron-sulfur (Fe-S) clusters (453 aa)
       
  0.897
ABCI9
ATP-binding cassette I9 (470 aa)
   
  0.896
ABCI8
UPF0051 protein ABCI8; Involved in light signaling, probably by mediating the transport and correct distribution of protoporphyrin IX, a chlorophyll precursor, in response to far-red light (557 aa)
