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

mtnNMethylthioadenosine / S-adenosylhomocysteine nucleosidase; Catalyzes the irreversible cleavage of the glycosidic bond in both 5'-methylthioadenosine (MTA) and S-adenosylhomocysteine (SAH/AdoHcy) to adenine and the corresponding thioribose, 5'- methylthioribose and S-ribosylhomocysteine, respectively. Belongs to the PNP/UDP phosphorylase family. MtnN subfamily. (231 aa)    
Predicted Functional Partners:
luxS
S-ribosylhomocysteine lyase; Involved in the synthesis of autoinducer 2 (AI-2) which is secreted by bacteria and is used to communicate both the cell density and the metabolic potential of the environment. The regulation of gene expression in response to changes in cell density is called quorum sensing. Catalyzes the transformation of S-ribosylhomocysteine (RHC) to homocysteine (HC) and 4,5-dihydroxy-2,3-pentadione (DPD); Belongs to the LuxS family.
 
 
 0.998
yrrT
Putative AdoMet-dependent methyltransferase; Could be a S-adenosyl-L-methionine-dependent methyltransferase; Belongs to the methyltransferase superfamily. YrrT family.
  
 
 0.994
mtnK
Methylthioribose kinase (methionine salvage pathway); Catalyzes the phosphorylation of methylthioribose into methylthioribose-1-phosphate.
  
  
 0.993
mccA
Cystathionine beta-synthase for the reverse transsulfuration pathway; Catalyzes the conversion of O-acetylserine and homocysteine to cystathionine.
  
  
 0.975
mccB
Cystathionine gamma-lyase and homocysteine gamma-lyase for reverse transsulfuration pathway; Catalyzes the conversion of cystathionine to cysteine, and homocysteine to sulfide.
  
 
 0.917
metK
S-adenosylmethionine synthetase; Catalyzes the formation of S-adenosylmethionine (AdoMet) from methionine and ATP. The overall synthetic reaction is composed of two sequential steps, AdoMet formation and the subsequent tripolyphosphate hydrolysis which occurs prior to release of AdoMet from the enzyme.
  
 
 0.910
speE
Spermidine synthase; Involved in the cell growth and proliferation. Catalyzes the irreversible transfer of a propylamine group from the amino donor S- adenosylmethioninamine (decarboxy-AdoMet) to putrescine (1,4- diaminobutane) to yield spermidine (Probable). Belongs to the spermidine/spermine synthase family.
  
 
 0.904
bsuMA
Conserved hypothetical protein; This methylase may recognize the double-stranded sequence CTCGAG, causing specific methylation on C-? on both strands, and protects the DNA from cleavage by the BsuMI endonuclease. Belongs to the class I-like SAM-binding methyltransferase superfamily. C5-methyltransferase family.
    
  0.902
bsuMB
DNA-methyltransferase (cytosine-specific); This methylase may recognize the double-stranded sequence CTCGAG, causing specific methylation on C-? on both strands, and protects the DNA from cleavage by the BsuMI endonuclease. Belongs to the class I-like SAM-binding methyltransferase superfamily. C5-methyltransferase family.
    
  0.902
mtbP
DNA (cytosine-5-)-methyltransferase; This enzyme methylates the first cytosine within the sequences GGCC and GCNGC; Belongs to the class I-like SAM-binding methyltransferase superfamily. C5-methyltransferase family.
