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

malMolybdenum cofactor sulfurase; 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. (781 aa)    
Predicted Functional Partners:
IscU
Iron-sulfur cluster assembly enzyme; Scaffold protein for the de novo synthesis of iron-sulfur (Fe-S) clusters within mitochondria, which is required for maturation of both mitochondrial and cytoplasmic [2Fe-2S] and [4Fe-4S] proteins.
  
 
 0.999
cin
Molybdenum cofactor synthesis protein cinnamon; Catalyzes two steps in the biosynthesis of the molybdenum cofactor. In the first step, molybdopterin is adenylated. Subsequently, molybdate is inserted into adenylated molybdopterin and AMP is released; In the N-terminal section; belongs to the MoaB/Mog family.
  
 
 0.980
Mocs1
Cyclic pyranopterin monophosphate synthase; Isoform Mocs1a and isoform Mocs1b probably form a complex that catalyzes the conversion of 5'-GTP to cyclic pyranopterin monophosphate (cPMP). Mocs1a catalyzes the cyclization of GTP to (8S)- 3',8-cyclo-7,8-dihydroguanosine 5'-triphosphate and Mocs1b catalyzes the subsequent conversion of (8S)-3',8-cyclo-7,8-dihydroguanosine 5'- triphosphate to cPMP; In the C-terminal section; belongs to the MoaC family.

shop
Probable sulfite oxidase, mitochondrial; Molybdenum ion binding; sulfite oxidase activity; heme binding; molybdopterin cofactor binding. It is involved in the biological process described with: sulfur compound metabolic process; nitrate assimilation; oxidation-reduction process.
  
  
 0.884
alpha-Est8
Carboxylic ester hydrolase activity; Belongs to the type-B carboxylesterase/lipase family.
      
 0.790
ry
Xanthine dehydrogenase; Key enzyme in purine degradation. Catalyzes the oxidation of hypoxanthine to xanthine. Catalyzes the oxidation of xanthine to uric acid (By similarity).
  
  
 0.762
Mocs2B
Molybdopterin synthase catalytic subunit; Catalytic subunit of the molybdopterin synthase complex, a complex that catalyzes the conversion of precursor Z into molybdopterin. Acts by mediating the incorporation of 2 sulfur atoms from thiocarboxylated Mocs2A into precursor Z to generate a dithiolene group; Belongs to the MoaE family. MOCS2B subfamily.
  
  
 0.753
CG11710
Uncharacterized protein, isoform B; Transcription coactivator activity; zinc ion binding. It is involved in the biological process described with: positive regulation of transcription, DNA-templated.
 
 
    0.728
Uba4
Adenylyltransferase and sulfurtransferase MOCS3; Plays a central role in 2-thiolation of mcm(5)S(2)U at tRNA wobble positions of cytosolic tRNA(Lys), tRNA(Glu) and tRNA(Gln) (By similarity). Also essential during biosynthesis of the molybdenum cofactor (By similarity). Acts by mediating the C-terminal thiocarboxylation of sulfur carriers URM1 and MOCS2A. Its N-terminus first activates URM1 and MOCS2A as acyl-adenylates (- COAMP), then the persulfide sulfur on the catalytic cysteine is transferred to URM1 and MOCS2A to form thiocarboxylation (-COSH) of their C-terminus (By similarity).

Cbs
Cystathionine beta-synthase (Cbs) encodes an enzyme involved in endoplasmic reticulum stress response; Belongs to the cysteine synthase/cystathionine beta- synthase family.
