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 [...] (469 aa)    
Predicted Functional Partners:
hsdM
DNA methylase M, host modification; Methylation of specific adenine residues; required for both restriction and modification activities (By similarity). The StySJI enzyme recognizes 5'-GAGN(6)GTRC-3'; Belongs to the N(4)/N(6)-methyltransferase family.
 
 0.999
hsdR
Host restriction; similar to E. coli host restriction; endonuclease R (AAC77306.1); Blastp hit to AAC77306.1 (1188 aa), 91% identity in aa 20 - 1188.
 
 
 0.999
mrr
Similar to E. coli restriction of methylated adenine (AAC77307.1); Blastp hit to AAC77307.1 (304 aa), 77% identity in aa 1 - 304.
 
  
 0.965
mod
DNA methylase; Binds the system-specific DNA recognition site 5'-CAGAG-3'. Necessary for restriction and for methylation of A-4.
     
 0.913
ydaL
Putative Smr domain protein; Similar to E. coli orf, hypothetical protein (AAC74422.1); Blastp hit to AAC74422.1 (187 aa), 86% identity in aa 1 - 187.
      
 0.897
ybjD
Homology with RecF protein; Similar to E. coli orf, hypothetical protein (AAC73963.1); Blastp hit to AAC73963.1 (552 aa), 89% identity in aa 1 - 552.
  
  
 0.771
rhuM
Putative cytoplasmic protein; Pathogenicity island encoded protein: SPI3; RhuM (gi|4324608).
 
    0.758
yjiS
Putative cytoplasmic protein; Similar to E. coli orf, hypothetical protein (AAC77297.1); Blastp hit to AAC77297.1 (54 aa), 55% identity in aa 1 - 54.
      
 0.742
recD
Exonuclease V, alpha chain; A helicase/nuclease that prepares dsDNA breaks (DSB) for recombinational DNA repair. Binds to DSBs and unwinds DNA via a highly rapid and processive ATP-dependent bidirectional helicase activity. Unwinds dsDNA until it encounters a Chi (crossover hotspot instigator) sequence from the 3' direction. Cuts ssDNA a few nucleotides 3' to the Chi site. The properties and activities of the enzyme are changed at Chi. The Chi-altered holoenzyme produces a long 3'-ssDNA overhang and facilitates RecA-binding to the ssDNA for homologous DNA recombination and repair. Holo [...]
