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

PMM0577Putative type II alternative sigma factor, sigma70 family; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. (307 aa)    
Predicted Functional Partners:
dnaG
CHC2 zinc finger:Toprim domain; RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication.
  
 0.832
PMM0575
Conserved hypothetical; Alternative locus ID: PMED4_06241.
  
    0.811
PMM0576
Conserved hypothetical protein; Alternative locus ID: PMED4_06251.
  
    0.811
rpoB
RNA polymerase beta subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
   
 
 0.653
rpoZ
Putative DNA-directed RNA polymerase (omega chain); Promotes RNA polymerase assembly. Latches the N- and C- terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits.
   
 
 0.611
rpoA
Bacterial RNA polymerase, alpha chain; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
   
 
 0.609
trmD
Putative bifuntional enzyme: tRNA methyltransferase; Involved in the biosynthesis of isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP), two major building blocks of isoprenoid compounds. Catalyzes the conversion of 4-diphosphocytidyl-2- C-methyl-D-erythritol 2-phosphate (CDP-ME2P) to 2-C-methyl-D-erythritol 2,4-cyclodiphosphate (ME-CPP) with a corresponding release of cytidine 5-monophosphate (CMP); Belongs to the RNA methyltransferase TrmD family.
 
    0.595
hisI
Phosphoribosyl-AMP cyclohydrolase; Alternative locus ID: PMED4_06271; In the C-terminal section; belongs to the PRA-PH family.
  
    0.503
trxB
FAD-dependent pyridine nucleotide-disulphide oxidoreductase; Alternative locus ID: PMED4_02171.
  
  
 0.486
PMM0579
Conserved hypothetical protein; Alternative locus ID: PMED4_06281.
