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

trxB1Thioredoxin reductase; The active site of this enzyme is a redox-active disulfide bond. TrxB uses the FAD to shuttle reducing equivalents from NAD(P)H to a Cys residue that is usually a part of a redox-active disulphide bridge. In a second step, the reduced disulphide reduces the substrate; Acts as an homodimer and binds one FAD molecule per subunit; Belongs to the class 2 of the pyridine nucleotide- disulphide reductases (PNDR); Localized in the cytoplasm; High confidence in function and specificity. (321 aa)    
Predicted Functional Partners:
trxA
Thioredoxin is a small disulfide-containing redox protein that participates in various redox reactions through the reversible oxidation of its active center dithiol to a disulfide and catalyzes dithiol-disulfide exchange reactions; Localized in the cytoplasm; High confidence in function and specificity.

metB
The Cystathionine gamma-synthase is found in the Selenoamino acid metabolism pathway and involved in the second step of the methionine biosynthesis; Uses a pyridoxal phosphate group as cofactor, attached to a lysine residue located in the central section of the enzyme; Localized in the cytoplasm; High confidence in function and specificity.
   
 
 0.905
sufS
Cysteine desulfurase; Catalyzes the removal of elemental sulfur and selenium atoms from L-cysteine, L-cystine, L-selenocysteine, and L-selenocystine to produce L-alanine.
  
 
 0.905
moeB
Molybdopterin synthase activating protein; Enzyme involved in the biosynthesis of molybdopterin cofactor, necessary for molybdoenzymes. Plays a role in the activation of the small subunit of the molybdopterin converting factor (moaD); Contains a N- terminal transmembrane segment and a C-terminal rhodanese domain; Belongs to the hesA/moeB/thiF family; Localized in the cytoplasmic membrane; High confidence in function and specificity.
  
  
 0.547
rplE
Ribosomal protein L5; This is 1 of the proteins that binds and probably mediates the attachment of the 5S RNA into the large ribosomal subunit, where it forms part of the central protuberance. In the 70S ribosome it contacts protein S13 of the 30S subunit (bridge B1b), connecting the 2 subunits; this bridge is implicated in subunit movement. Contacts the P site tRNA; the 5S rRNA and some of its associated proteins might help stabilize positioning of ribosome-bound tRNAs.

trxA-3
Thioredoxin is a small disulfide-containing redox protein that serves as a general protein disulfide oxidoreductase; Localized in the cytoplasm; High confidence in function and specificity.
 
 
 0.516
rplF
Ribosomal protein L6; This protein binds to the 23S rRNA, and is important in its secondary structure. It is located near the subunit interface in the base of the L7/L12 stalk, and near the tRNA binding site of the peptidyltransferase center; Belongs to the universal ribosomal protein uL6 family.
  
   
 0.454
cysS
Cysteinyl-tRNA synthetase catalyzes the attachment of cysteine to its cognate transfer RNA molecule in a highly specific two-step reaction. It is a monomer and belongs to the class I of the aminoacyl-tRNA synthetases. It binds one zinc ion as cofactor. Localized in the cytoplasm; High confidence in function and specificity.

CAZ98744.1
Peroxiredoxins are thiol peroxidase involved in redox regulation of the cell. Can reduce H(2)O(2), short chain organic, fatty acid, and phospholipid hydroperoxides. The peroxidase reaction comprises two steps centered around a redox-active cysteine called the peroxidatic cysteine. It oxidized the peroxide substrate to S-hydroxycysteine (a sulfenic acid). The second step is the regeneration of cysteine from S-hydroxycysteine. This regeneration is due to thiol-containing reductants such as thioredoxin; Localized in the cytoplasm; Specificity unclear.
