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

ydcPPutative peptidase; Responsible for the formation of the 5-hydroxycytidine modification at the C2501 position (ho5C2501) of 23S rRNA. May be a Fe- S protein that catalyzes ho5C2501 formation using prephenate as a hydroxyl group donor. (653 aa)    
Predicted Functional Partners:
yhbV
U32 peptidase family protein; Required for O(2)-independent ubiquinone (coenzyme Q) biosynthesis. Together with UbiU, is essential for the C6-hydroxylation reaction in the oxygen-independent ubiquinone biosynthesis pathway.
 
  
 0.943
ydcN
Putative DNA-binding transcriptional regulator; Regulates the expression of 12-16 transcription units involved in various steps of sulfur utilization. Represses expression of pfkB, fliZ, cysE, ydcO and its own expression. Activates expression of ypfN. Acts by binding to SutR boxes.
 
  
 0.883
yhaB
Uncharacterized protein.
      
 0.810
ygcN
Putative oxidoreductase; Probably accepts electrons from YgcQ/YgcR and reduces a quinone; Belongs to the ETF-QO/FixC family.
      
 0.808
cmoA
carboxy-SAM synthase; Catalyzes the conversion of S-adenosyl-L-methionine (SAM) to carboxy-S-adenosyl-L-methionine (Cx-SAM); Belongs to the class I-like SAM-binding methyltransferase superfamily. Cx-SAM synthase family.
   
  
 0.672
cmoB
tRNA (cmo5U34)-carboxymethyltransferase, carboxy-SAM-dependent; Catalyzes carboxymethyl transfer from carboxy-S-adenosyl-L- methionine (Cx-SAM) to 5-hydroxyuridine (ho5U) to form 5- carboxymethoxyuridine (cmo5U) at position 34 in tRNAs. Can also catalyze the SAM-dependent methylation of ho5U, with much lower efficiency.
  
  
 0.639
rlmN
Dual specificity 23S rRNA m(2)A2503, tRNA m(2)A37 methyltransferase, SAM-dependent; Specifically methylates position 2 of adenine 2503 in 23S rRNA and position 2 of adenine 37 in tRNAs. m2A2503 modification seems to play a crucial role in the proofreading step occurring at the peptidyl transferase center and thus would serve to optimize ribosomal fidelity. Unmodified tRNA is not a suitable substrate for RlmN, which suggests that RlmN works in a late step during tRNA maturation. Belongs to the radical SAM superfamily. RlmN family.
  
 
 0.599
selB
selenocysteinyl-tRNA-specific translation factor; Translation factor necessary for the incorporation of selenocysteine into proteins. It probably replaces EF-Tu for the insertion of selenocysteine directed by the UGA codon. SelB binds GTP and GDP; Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. SelB subfamily.
    
   0.577
ykgJ
UPF0153 cysteine cluster protein; Putative ferredoxin; Protein involved in electron carrier activity; To A.calcoaceticus putative ferredoxin.
  
     0.532
yegQ
Putative peptidase; Belongs to the peptidase U32 family.
