STRINGSTRING
SRX protein (Arabidopsis thaliana) - STRING interaction network
"SRX" - Sulfiredoxin, chloroplastic/mitochondrial 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

SRXSulfiredoxin, chloroplastic/mitochondrial; Contributes to oxidative stress resistance by reducing cysteine-sulfinic acid formed under exposure to oxidants in a peroxiredoxin. May catalyze the reduction in a multi-step process by acting both as a specific phosphotransferase and a thioltransferase. Required to switch on the antioxidant pathway to regenerate the oxidative damage. In mitochondrion, catalyzes the retroreduction of the inactive sulfinic form of atypical Prx IIF using thioredoxin as reducing agent (198 aa)    
Predicted Functional Partners:
NTRC
NADPH-dependent thioredoxin reductase 3; Thioredoxin reductase (TR) that exhibits both TR and thioredoxin (Trx) activities. Contains a C-terminal functional Trx domain. Functions as an electron donor for plastidial 2-Cys peroxiredoxins and participates in a NADPH-dependent hydrogen peroxide scavenging system in chloroplasts in the dark. Required for chlorophyll biosynthesis and biogenesis of the photosynthetic apparatus. Activates aerobic cyclase which converts Mg- protoporhyrin monomethyl ester into protochlorophyllide. Involved in a light-dependent regulation of starch biosynthesis b [...] (529 aa)

At5g06290
2-Cys peroxiredoxin BAS1-like, chloroplastic; Thiol-specific peroxidase that catalyzes the reduction of hydrogen peroxide and organic hydroperoxides to water and alcohols, respectively. Plays a role in cell protection against oxidative stress by detoxifying peroxides. May be an antioxidant enzyme particularly in the developing shoot and photosynthesizing leaf; Belongs to the peroxiredoxin family. AhpC/Prx1 subfamily (273 aa)

AT3G11630
2-Cys peroxiredoxin BAS1, chloroplastic; Thiol-specific peroxidase that catalyzes the reduction of hydrogen peroxide and organic hydroperoxides to water and alcohols, respectively. Plays a role in cell protection against oxidative stress by detoxifying peroxides. May be an antioxidant enzyme particularly in the developing shoot and photosynthesizing leaf; Belongs to the peroxiredoxin family. AhpC/Prx1 subfamily (266 aa)

        0.912
NTRA
NADPH-dependent thioredoxin reductase A; Possesses thioredoxin-disulfide reductase activity towards thioredoxins O1, O2 and F3; Belongs to the class-II pyridine nucleotide-disulfide oxidoreductase family (378 aa)
     
   
  0.911
TRE1

  0.905
CAT
Catalase-2; Encodes a peroxisomal catalase, highly expressed in bolts and leaves. mRNA expression patterns show circadian regulation with mRNA levels being high in the subjective early morning. Loss of function mutations have increased H2O2 levels and increased H2O2 sensitivity. Mutants accumulate more toxic ions yet show decreased sensitivity to Li+. This decreased sensitivity is most likely due to an insensitivity to ethylene. Note that in Queval et al. (2007) Plant Journal, 52(4)-640, SALK_057998 is named as cat2-1, SALK_076998 is named as cat2-2; in Bueso et al. (2007) Plant Jou [...] (492 aa)
