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

defPeptide deformylase; Removes the formyl group from the N-terminal Met of newly synthesized proteins. Requires at least a dipeptide for an efficient rate of reaction. N-terminal L-methionine is a prerequisite for activity but the enzyme has broad specificity at other positions. (202 aa)    
Predicted Functional Partners:
fmt
methionyl-tRNA formyltransferase; Attaches a formyl group to the free amino group of methionyl- tRNA(fMet). The formyl group appears to play a dual role in the initiator identity of N-formylmethionyl-tRNA by promoting its recognition by IF2 and preventing the misappropriation of this tRNA by the elongation apparatus; Belongs to the Fmt family.

rplV
LSU ribosomal protein L22P; This protein binds specifically to 23S rRNA; its binding is stimulated by other ribosomal proteins, e.g. L4, L17, and L20. It is important during the early stages of 50S assembly. It makes multiple contacts with different domains of the 23S rRNA in the assembled 50S subunit and ribosome (By similarity).
    
   0.907
rpsT
SSU ribosomal protein S20P; Binds directly to 16S ribosomal RNA.
  
 
 0.875
rplU
LSU ribosomal protein L21P; This protein binds to 23S rRNA in the presence of protein L20; Belongs to the bacterial ribosomal protein bL21 family.
 
   0.869
tig
Trigger factor; Involved in protein export. Acts as a chaperone by maintaining the newly synthesized protein in an open conformation. Functions as a peptidyl-prolyl cis-trans isomerase; Belongs to the FKBP-type PPIase family. Tig subfamily.

rpmA
LSU ribosomal protein L27P; Alternative locus ID: NATL2_17151; Belongs to the bacterial ribosomal protein bL27 family.
 
   0.865
rpsU
SSU ribosomal protein S21P; Alternative locus ID: NATL2_18761; Belongs to the bacterial ribosomal protein bS21 family.
  
 
 0.860
rplT
LSU ribosomal protein L20P; Binds directly to 23S ribosomal RNA and is necessary for the in vitro assembly process of the 50S ribosomal subunit. It is not involved in the protein synthesizing functions of that subunit.
  
   0.860
rplQ
LSU ribosomal protein L17P; Alternative locus ID: NATL2_19271.
    
   0.856
rpsJ
SSU ribosomal protein S10P; Involved in the binding of tRNA to the ribosomes. Belongs to the universal ribosomal protein uS10 family.
