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

hsdSSpecificity determinant for hsdM and hsdR; The M and S subunits together form a methyltransferase (MTase) that methylates two adenine residues in complementary strands of a bipartite DNA recognition sequence. In the presence of the R subunit the complex can also act as an endonuclease, binding to the same target sequence but cutting the DNA some distance from this site. Whether the DNA is cut or modified depends on the methylation state of the target sequence. When the target site is unmodified, the DNA is cut. When the target site is hemimethylated, the complex acts as a maintenance M [...] (464 aa)

hsdR
Endonuclease R Type I restriction enzyme; The EcoKI enzyme recognizes 5'-AACN(6)GTGC-3'. Subunit R is required for both nuclease and ATPase activities, but not for modification; Belongs to the HsdR family.
 
 0.999
mcrB
5-methylcytosine-specific restriction enzyme McrBC, subunit McrB; Recognizes N4- and C5-methylcytosine (and 5-hydroxy- methylcytosines) produced by a broad range of DNA methylases and appears to act against 5-methylcytosine preceded by a purine residue. Binds to DNA containing methylated cytosines; also binds to GTP. Isoform 33 kDa is less active than isoform 51 kDa and may play a role in regulating the activity of isoform 51 kDa by competing with it in DNA and protein binding abilities.

mrr
Methylated adenine and cytosine restriction protein; Involved in the acceptance of foreign DNA which is modified. Restricts both adenine- and cytosine-methylated DNA.
 
  
 0.932
ompT
DLP12 prophage; Protease that can cleave T7 RNA polymerase, ferric enterobactin receptor protein (FEP), antimicrobial peptide protamine and other proteins. This protease has a specificity for paired basic residues.
   
  
 0.922
proA
Gamma-glutamylphosphate reductase; Catalyzes the NADPH-dependent reduction of L-glutamate 5- phosphate into L-glutamate 5-semialdehyde and phosphate. The product spontaneously undergoes cyclization to form 1-pyrroline-5-carboxylate. Belongs to the gamma-glutamyl phosphate reductase family.
      
 0.892
mcrA
Putative 5-methylcytosine/5-hydroxymethylcytosine-specific restriction nuclease; Restriction of 5-methyl and 5-hydroxymethylcytosines at the specific DNA sequence C(me)CGG.
  
  
 0.842
mcrC
Protein McrC; Modifies the specificity of McrB restriction by expanding the range of modified sequences restricted. Does not bind to DNA.
  
  
 0.838
ybjD
Putative OLD family ATP-dependent endonuclease; DUF2813 family protein.
  
  
 0.795
rpsL
30S ribosomal subunit protein S12; With S4 and S5 plays an important role in translational accuracy. Cryo-EM studies suggest that S12 contacts the EF-Tu bound tRNA in the A-site during codon-recognition. This contact is most likely broken as the aminoacyl-tRNA moves into the peptidyl transferase center in the 50S subunit; Belongs to the universal ribosomal protein uS12 family.
